Silica Gel

Silica Alumina Gel is a high-performance desiccant which consists of a mixture of silicon dioxide (SiO) and aluminum oxide (AlO), used for adsorbing moisture in high-humidity and high-temperature conditions. It often exists in the form of white or pale yellow beads or granules and exhibits very good adsorption properties along with improved thermal stability when compared to standard silica gel. Its 2 to 5 mm bead size provides a moisture adsorption capacity of up to 30% by weight and is regenerated at 120ï150C. It is the perfect product for processes like gas drying, petrochemical operations, and industrial air systems, where resistance to harsh conditions and efficiency are paramount.

Blue desiccant silica gel is a dryness-indicating absorption agent formulated from amorphous silicon dioxide and cobalt chloride, which causes it to turn deep blue when in its dry state. It is an indicating silica gel that changes from blue to pink upon moisture absorption, giving a clear visual indication of saturation. The beads are usually 1ï3 mm or 2ï4 mm in diameter and are able to soak up to 30ï35% of their weight in water at 100% relative humidity. Blue silica gel is found in electronics, machinery, optics, and industrial packaging applications and is effective but includes cobalt chloride, a poisonous chemical, and so is not suggested for use with, pharmaceuticals, or other sensitive products.

Crystal Silica Gel is an extremely efficient desiccant made up of amorphous silicon dioxide (SiO), which is meant to regulate humidity by adsorbing water from the surrounding atmosphere. It is in the form of hard, transparent or semi-transparent beads or crystals and is also found in many different forms, some of which are non-indicating white gel and indicating varieties like blue and orange. The blue type has cobalt(II) chloride as an ingredient, which becomes pink when it is saturated. The orange type employs a non-toxic indicator that decolorizes or turns green on absorbing moisture. Crystal silica gel has a high surface area and can absorb as much as 30% of its weight in water. It is commonly used in packaging, electronics, pharmaceuticals, and other applications where it is important to control moisture. It can be reused via heating and provides a consistent, effective solution for long-term protection from humidity.

Orange Silica Gel is an eco-friendly, non-toxic desiccant used to absorb moisture and protect products from humidity damage. Unlike traditional blue silica gel (which contains cobalt chloride, a known carcinogen), orange silica gel is cobalt-free and considered safe for pharmaceuticals, and consumer goods packaging. It offers all the performance benefits of standard silica gel while providing a visual indication of moisture saturation

White non-indicating silica gel is an amorphous silicon dioxide moisture-absorbing desiccant in the form of hard, translucent white beads or granules. It remains white without color change when absorbing moisture and is ideal for use where visual indication is unnecessary. The bead size is usually 1 3 mm or 2 4 mm, with up to 30 35% of moisture absorption by weight at 100% relative humidity. It is odorless, chemically inert, and safe for use with electronics, pharmaceuticals, and general storage. Silica gel is usually packaged in breathable materials like paper, Tyvek, or non-woven fabric in order to permit effective exchange of moisture.

Non-indicating silica gel beads are clear or white desiccant beads composed of Type A silica gel, intended for adsorption of moisture and humidity control across various applications. The beads do not show color change upon saturation, thus can be used in areas where visual indication of moisture is not necessary. Commonly measuring between 1 and 5 mm, they are high in adsorptive capacity, able to take up to 30ï35% of their weight in water based on relative humidity. Non-indicating silica gel is commonly applied in packaging, electronics, pharmaceuticals, and storage solutions to inhibit mold, corrosion, and spoilage. The beads are inert chemically, non-toxic, and safe to work around most materials, and they are generally RoHS and REACH compliant.

Desiccant silica gel is a strong adsorbing material, capable of absorbing moisture and made from amorphous silicon dioxide (SiO). It finds extensive use in shielding commodities from moisture-induced damage while allowing them to be stored or transported. It occurs either as bead or granular type, is porous, and possesses a high surface area. Due to these characteristics, it is capable of adsorbing 30ï35% of its own weight of water.

Silica Gel Powder is high-surface-area amorphous silicon dioxide (SiO) ground into fine powder, employed mainly for adsorbing moisture and as a drying agent in industries. It is generally of particle size less than 100 microns, bulk density 0.3ï0.5 g/cmï, and adsorption capacity for moisture 30ï35% by weight.

White Non-Indicating Silica Gel is a moisture-absorbing desiccant made from pure, amorphous silicon dioxide (SiO) and is widely used to control humidity in enclosed spaces. Unlike indicating silica gels, which change color when saturated, white non-indicating silica gel has no visual moisture indicatorïit remains white before and after absorbing moisture. Despite its simple appearance, it is highly effective, capable of adsorbing up to 25ï20% of its own weight in water vapor depending on relative humidity.

Orange crystal silica gel is a desiccant, a moisture-absorbing product made of silicon dioxide (SiO) in the form of small orange beads measuring 2ï4 mm,4-6 mm , 6-12 mm, 12-16 mm. It has a moisture indicator that turns from orange upon drying to green when it is saturated, so it can be easily checked for effectiveness. It has a large surface area of 500ï750 mï/g and a pore size of about 60 angstroms and effectively draws moisture from the atmosphere. Its adsorption varies from 9% at 20% relative humidity to 36% at 80% relative humidity. It has a bulk density of 0.72ï0.78 g/cmï and may be regenerated for reuse by heating at 100ï130C for 2 to 4 hours. Orange silica gel has a shelf life that can last up to five years when kept properly in a cool, dry location.

Blue silica gel is a color-changing desiccant with cobalt chloride as its constituent, which turns deep blue when in dry state and pink upon absorbing moisture, indicating saturation. The beads are usually 1ï3 mm or 2ï4 mm in size and have the capacity to adsorb 30ï35% of their weight in water at 100% relative humidity. Common in use for controlling moisture in electronics, machinery, and packaging, blue silica gel is easy to see as it is effective but is not safe for food or pharmaceutical use because it contains toxic cobalt chloride.

DMF-free silica gel is a non-toxic, trace-DMF-free desiccant that does not contain the toxic chemical dimethyl fumarate, which is occasionally used as an anti-mold agent. It is safe to use in sensitive applications like pharmaceuticals, food packaging, textiles, and consumer products, particularly in areas where DMF is prohibited (e.g., the EU). It is usually sold in orange or white beads and has the ability to absorb 30ï35% of its weight in water at 100% relative humidity. It is odorless, non-toxic, and comes in packaging made from breathable materials such as paper, Tyvek, or non-woven fabric. Lack of DMF makes it compliant with global safety standards and can be directly used with sensitive or edible products.

Blue Crystal Silica Gel is a desiccant that absorbs moisture and is composed of silicon dioxide (SiO) with cobalt(II) chloride as a water indicator. It is in the form of pale blue crystals or beads and changes color to pink upon saturation, easily showing when replacement or regeneration is necessary. This silica gel is very powerful, with the capability to adsorb between 30% of its own weight in water, and is widely utilized in electronics, pharmaceuticals, textiles, and packaging fields to manage humidity and avoid mold, corrosion, or spoilage. It is usually available in bead sizes between 1 and 8 mm and can be regenerated through heating at 100 120C. Though it is effective, care is needed because the presence of cobalt(II) chloride makes it a toxic and possibly carcinogenic chemical. It is for this reason that safer alternatives like orange-indicating silica gel are recommended for use where non-toxic substances are needed.

Mix Silica Gel is a combination of non-indicating clear and indicating colored silica gel beads, typically orange or blue. Color-changing beads indicate moisture saturation by changing color from orange to green or blue to pink. The mixture provides equalized moisture adsorption with convenient visual tracking. Typical capacity for moisture adsorption is 20ï30% by weight. Bulk density is between 0.6 and 0.8 g/cmï. Regeneration temperature is 100ï130C. Applied extensively for packing, protection of electronic devices, and industrial drying.

Blue crystal silica gel is a colorless, glass-like desiccant consisting of silicon dioxide (SiO) and 0.5ï1% cobalt(II) chloride as an indicator of moisture. It is blue crystals that become pink upon saturation, which is a clear visual indication of moisture uptake. The crystals are usually 1-2 mm,2-4 mm,4-6mm,6-9mm, 9-12mm in size and possess a bulk density of 0.65 to 0.75 g/cmï. It has a large surface area of about 750 mï/g and a mean pore diameter of about 60 angstroms and so can adsorb 30ï35% of its own weight in water. The gel can be regenerated by heating at 100ï120C to restore the original blue color. It operates optimally at a pH range of between 4 and 8 and is hence ideally placed for industrial and electronic use, although it must be handled carefully because of the toxic nature of cobalt chloride.

Blue signifying silica gel is a moisture-absorbing desiccant that mainly consists of silicon dioxide (SiO) with about 0.5 1% cobalt(II) chloride, which is used as a moisture indicator. Blue granules or blue beads are seen, and it shifts color from blue in the dry state to pink when wet, allowing for easy visual detection of moisture absorption. This silica gel is usually 97% SiO and comes in particle sizes from 1 to 5 mm. The high surface area is approximately 750 m /g and pore size is approximately 60 angstroms, which enables it to adsorb 30 35% of its weight in water. It has a bulk density of 0.65 0.75 g/cm and an effective pH range of 4 to 8. Blue indicating silica gel is effective for industrial drying and moisture control. It can be regenerated by heating at 100 120C. It is considered toxic due to the presence of cobalt(II) chloride and must not be used in contact with food, pharmaceuticals, or personal care products.

DMF-Free Silica Gel refers to silica gel that is manufactured without the use of Dimethyl Fumarate (DMF), a chemical once used in some desiccants for its antifungal properties but now widely banned due to its toxic and allergenic effects. DMF-free silica gel is a safe, non-toxic, and environmentally friendly alternative that provides the same excellent moisture-absorbing performance without the health risks associated with DMF exposure.

Non-indicating silica gel is a desiccant used to absorb moisture that is produced from high-purity silicon dioxide (SiO), generally ï98%, and is in the form of transparent or white beads or crystals. It does not, unlike indicating silica gel, color when saturated, and as such, it is suitable for use where visual inspection is not required or even allowed, e.g., in pharmaceuticals, and electronics. It has a high surface area of about 750 mï/g and a pore diameter of about 60 angstroms, and it can adsorb as much as 30ï35% of its weight in water. It has a bulk density of 0.65 to 0.75 g/cmï and an effective pH range of 4 to 8, and it is chemically stable as well as non-toxic. Non-indicating silica gel can be restored through heating at 110ï120C and is thus a reusable and effective option for industrial and commercial humidity control.

Orange to Dark Green Indicating Type Silica Gel Beads are eco-friendly, non-toxic desiccant silica gel beads consisting of amorphous silicon dioxide (SiO) with a secure moisture indicator. The beads are bright orange in color when dry and transition to dark green as they take up moisture, offering an evident color change with their level of saturation. Generally measuring 2 to 4 mm in size, they have a high moisture adsorption abilityïup to 30% of their weightïthus making them suitable for packaging sensitive products in electronics, pharmaceuticals, food packaging, and others. Having a bulk density of about 700ï800 kg/mï and a pH level of 4 to 8, they can be regenerated by heating to 100ï120C for reuse.

Silica gel is capable of adsorbing 30ï35% of its weight in water vapor, having a bulk density of 700ï800 kg/mï and a pH of between 4 and 8. Silica gel is reusable after heating to 100ï120C and is commonly utilized in packaging, electronics, pharmaceuticals, and storage conditions for safeguarding products against damage from moisture. While white and orange varieties are safe and non-toxic, the blue variety is handled with care because it contains cobalt.

White silica gel is a non-indicating, highly porous form of silicon dioxide (SiOïnHO) renowned for its exceptional moisture adsorption capabilities. Comprising hard, translucent beads or granules, it operates through physical adsorption, effectively trapping water vapor within its extensive network of microscopic pores. This desiccant performs optimally at room temperatures (70ï90F) and high relative humidity levels (60ï90% RH), making it ideal for preserving the integrity of moisture-sensitive products. Key applications include safeguarding electronics, pharmaceuticals,and compressed air systems from humidity-induced damage. With a moisture adsorption capacity of up to 25ï27% by weight at 80% RH, white silica gel ensures prolonged protection. Additionally, it can be regenerated through heating at approximately 120C, allowing for multiple reuse cycles and offering an eco-friendly solution for moisture control.

Water-resistant silica gel is a modified desiccant designed to retain its moisture-adsorbing capabilities even in high-humidity or direct-contact moisture environments. Unlike conventional silica gel, which can lose structural integrity or form a gel-like substance when saturated, water-resistant variants are engineered to resist breakdown and maintain performance. These are often treated with hydrophobic coatings or formulated with additional materials to repel liquid water while still allowing water vapor adsorption. This makes them especially useful in applications where exposure to water is likelyïsuch as marine transport, outdoor electronics, high-humidity storage, and industrial environments. Like standard silica gel, they remain non-toxic, reusable, and compliant with safety standards, offering reliable moisture control in even the most challenging conditions.

White granules silica gel is an indicating, porous form of silicon dioxide (SiOïnHO), generally applied as a desiccant to regulate moisture and humidity. It exists in the form of white, transparent granules and is normally found in the sizes of 1ï3 mm, 2ï4 mm, or 3ï5 mm, depending on the intended application. The material is non-toxic, odorless, and non-flammable, hence can be utilized by a number of industries such as pharmaceuticals, food packaging, electronics, and transportation. It possesses an enormous surface area (600ï800 mï/g) and pore volume (0.35ï0.45 cmï/g), which allows it to effectively uptake moistureïup to 30ï35% of its own weight at 100% relative humidity. The bulk density is typically in the range of 700 to 800 g/L and has good mechanical strength with a crushing strength of more than 80 N for large granules. The silica gel has a pH value range of 4 to 8 when suspended in water and has more than 98% pure silicon dioxide content. As it contains no color indicator, it will not visibly change when saturated, in contrast to blue or orange indicating silica gels. White silica gel is usually applied in situations where visible indication of moisture is not desirable but satisfactory control over moisture is essential.
