Basic Model:
LIM6969-65A/B, LIM6969-50A/B, LIM6969-48A/B, LIM6969-45A/B

Product Description
As a two-component, platinum-catalyzed liquid silicone rubber (LSR), the product is ideal for injection molding process. Two components (A and B) are mixed by a proper ratio. Under the temperature of 20℃, the well sealed A/B mixture can be used for 5 days. As the temperature rises, the time reduces.

Features
High elastic resilience
Low volatility
High thermo stability
Low compression set

Main Applications
The liquid silicone rubber is mainly used as elastic roller coatings on the power charge roller (PCR) and developer roller (DR) of laser printers and copiers in office.

Packaging
20kg/pail or 200kg/pail
