Silica Gel Beads

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. The lack of poisonous cobalt compounds makes orange-to-dark-green silica gel a safer option compared to conventional blue indicating gels for consumer and industrial uses alike.

Blue Indicating Type Silica Gel Beads are glass-hard, glass-like beads made of silicon dioxide (SiO) and charged with cobalt(II) chloride, which is a moisture indicator. They are usually between 1 and 5 mm in size and blue when they are dry, red-pink as they pick up moisture, giving an obvious visual indication of saturation. They possess a high absorption capacity for waterï30% of their own weight at 100% relative humidityïand a bulk density of around 700ï800 kg/mï. With a pH between 4 and 8 and the capacity to be regenerated between 100ï120C, such beads are extensively applied in the field of electronics, pharmaceuticals, packaging, and instrument protection. But because of the inclusion of cobalt(II) chloride, which is toxic in nature, proper care and safety precautions must be exercised.

Orange to colorless silica gel beads are color-changing desiccants that shift from bright orange when dry to colorless upon moisture absorption, offering an easy-to-read visual indication of saturation. These cobalt-free beads are non-toxic and environmentally friendly, ensuring safe use in food, pharmaceuticals, electronics, and other sensitive applications. Usually 1ï4 mm in size, the beads can hold 30ï35% of their weight in water at 100% relative humidity. Sealed in breathable sachets of materials such as Tyvek or non-woven material, these silica gel beads provide consistent and safe moisture control with convenient monitoring through their color change function.

Mixed silica gel beads consist of white (non-indicating) silica gel combined with indicating silica gel beads (blue or orange) that offer both moisture absorption and a visual indication when they are saturated. The beads perform the dual role of being a good desiccant while enabling users to easily detect moisture. The white beads are absorbent, whereas colored indicating beads discolor upon saturation ï for instance, blue beads will turn pink or orange beads will turn green when saturated, depending upon the type of indicator. This mixture is particularly valuable in applications where visually monitoring humidity conditions is to be accomplished without the need for special equipment.

White silica gel beads are non-indicating, moisture-absorbing desiccant particles composed of Type A silica, used most commonly for humidity control in packaging and storage. The beads are usually 1-5 mm in diameter and possess a very high capacity for adsorption, absorbing 30-35% of their weight in water depending on the relative humidity. Chemically inert and color indicator-free, non-toxic white silica gel is an ideal product for all applications ranging from electronics to pharmaceuticals, And even textiles. The beads are RoHS and REACH compliant and have a shelf life of up to two years when stored under a dry, sealed condition.

Aquablue Orange Silica Gel Beads (2“4 mm) are top-performance, non-toxic desiccant beads for effective moisture uptake and visible humidity indication. The beads consist of amorphous silicon dioxide (SiO) and include a fully biodegradable orange indicator that slowly changes color”usually from orange to green or colorless”as the beads take up moisture. 2 to 4 millimeters in size, they provide an ideal balance between surface area and air permeability for instant moisture adsorption. Aquablue Orange Silica Gel is capable of adsorbing 30% of its weight in water vapor and has a bulk density of approximately 700“800 kg/m³. With a pH value of 4 to 8 and large surface area (‰600 m²/g), it is best for shielding delicate products like electronics, drugs, foodstuffs, and equipment. Aquablue Orange does not have toxic cobalt(II) chloride, unlike blue silica gel, thus being safe to use in consumer as well as industrial situations. It is easy to reuse by being heated at 100“120C and is usually packaged in sachets, packs, or in bulk as required by the application.

Non-indicating white silica gel beads are moisture-absorbing desiccants containing amorphous silicon dioxide, having the appearance of translucent white granules or beads. They are not color-changing upon adsorbing moisture, and hence used for applications where color indication is not necessary. They are generally 1ï4 mm in size and can hold 30ï35% of their weight in moisture under 100% relative humidity. They are chemically inert, odorless, and non-toxic and are safe to use within electronics, pharmaceuticals, and general storage. They come packaged in breathable materials like paper, Tyvek, or non-woven fabric and maintain consistent moisture control without the application of harmful chemicals.

Humidity controller silica gel is an extremely porous, moisture-trapping desiccant used to control humidity within confined areas. In bead or granular form, it usually traps up to 30“35% of its weight in water at 100% relative humidity. It is supplied in both non-indicating (white) and indicating (orange or blue) versions, with bead sizes usually 1“4 mm. The silica gel is also chemically stable, odorless, and non-toxic and, therefore, ideal for application in packaging, storage, and shipping of electronics, pharmaceuticals, and other sensitive materials to moisture. Frequently packaged in permeable materials like paper, Tyvek, or non-woven fabric, humidity controller silica gel provides consistent and effective moisture control against mold, corrosion, and degradation.

Pink color indicating silica gel beads are a cobalt-free, non-toxic desiccant that absorbs moisture and indicates saturation visually. The beads are pink when dry but turn light blue or pale violet as they absorb moisture, making them easy for users to track humidity levels. They are usually 1ï4 mm in size and have an extremely high capacity for absorbing moisture of 30ï35% of weight at 100% relative humidity. Produced from amorphous silicon dioxide, the beads are chemically inert, odorless, and safe to use in food packaging applications, pharmaceuticals, electronic products, and other sensitive products to moisture.
