Ultra Clear Silicone Rubber for Goggles


Product Description
This LIM3630 series silicone rubber from SQUARE is an ultra clear, high performance liquid silicone rubber made from a two-component system and catalyzed by platinum. It is suitable for injection molding of diving goggles.

The two-component silicone complies with the standards of USA FDA CFR 21.Part.177.2600, EN14350 for volatile compound and RoHS. After mixed in the prescribed amounts, the two components can be safely operated for 5 days under sealing condition and at 20℃. The rise of temperature will shorten the time.

Extremely high transparency
Excellent elastic resilience
Superb thermal stability and weather resistance (-60℃~250℃)
Anti heat aging

Main Application
The platinum cure silicone rubber is mainly used to making swimming goggles and other products that show high requirement for transparency.

20kg/pail or 200kg/pail
