Silicone rubber

Pyrogenic silica improves physical and mechanical properties of 2-component systems of silicone rubbers. Pyrogenic silica is used as thickener, filler and liquid component for reinforcement of elastomers which improves the properties of silicone rubbers, their elongation at break and tensile strength.

Pyrogenic silica of the grades FUMISIL200, FUMISIL300, and FUMISIL380 is used as an additive to silicone rubber, usually in concentration from 0.1% to 30%.
