: http://srsilicone.com/4-1-2-conductive-silicone-rubber/index.html

Basic Model:
LIM6968-15A/B, LIM6968-20A/B, LIM6968-30A/B, LIM6968-40A/B, LIM6968-50A/B, LSR6968-31A/B.

Product Description
The conductive silicone rubber designed for pressure roller is supplied as a two-component, platinum-cured silicone material. It is suitable for injection molding process. The mixture of A and B components can be safely operated for 5 days under sealing condition at a temperature of 20℃. As temperature rises, the time will be shortened.

Key Features
The injection silicone rubber is featured by high elastic resilience, low volatility, high thermal stability and low compression set.

Applications
The silicone rubber is mainly used as the surface elastic material on the conductive pressure roller of office facilities such as laser printers, copiers, and more.

Packaging
20kg/pail or 200kg/pail
