Insulating Silicone Rubber for Laser printer roller
Basic Model:
LSR6900-15A/B, LSR6900-20A/B, LSR6900-27A/B, LSR6900-30A/B, LIM6900-40A/B, LSR6900-50A/B
Product Description
This product is a two-component, platinum-catalyzed liquid silicone rubber, suitable for injection molding process. It is mainly used as elastic material on the insulating pressure roller of OA equipment such as laser printers, copiers, etc.
Key Features
The insulating silicone rubber comes with high elastic resilience, low volatility, high thermal stability and low compression set.
Packaging
20kg/pail or 200kg/pail
