Products Description of Silica Gel CAS#112926-00-8
Silicone gel is a special class of silicone rubber featuring low crosslink density and free of any fillers. Different from ordinary silicone rubber elastomers, it shows a transparent or translucent gel form, accompanied by extremely low mechanical strength. Its hardness cannot be easily tested via standard conventional methods, and needle penetration is generally adopted to assess its physical consistency.
Besides the inherent merits of silicone materials — wide high-low temperature resistance, safety, non-toxicity, favorable biocompatibility and superior electrical insulation — silicone gel also possesses unique gel-state functionalities, including vibration damping, adhesion and sealing capacity.

Product Application of Silica Gel CAS#112926-00-8
Benefiting from outstanding cushioning performance, colorless transparent appearance, customizable properties, easy processing and molding, favorable flowability and the capacity to fill tiny gaps and fine structures, silicone gel finds extensive applications in medical prosthetics, medical dressings, electronic & electrical potting and many other fields.
Its adoption in daily consumer goods has also grown rapidly. Owing to its non-toxic, non-irritating nature together with excellent cushioning and vibration-damping features, silicone gel is widely made into shoe sole cushion pads, seat cushions, underwear padding and a variety of other finished products.
