Overview
Silopren™ LSR 3386 is a 32A two-component, self-lubricating liquid silicone rubber used in injection molding. The self-lubricating property is achieved by a fluid that leaches out of the cured part over an extended period. This lubricating effect starts between a few hours to a day after the curing process is complete. LSR 3386 has a lower compression set after curing than the other self-lubricating grades.
Features & Benefits
- Low compression set
- Self-lubricating
- High thermal stability
- Flexibility at lower temperatures
- Resistance to aging
- Noncombustible
Problems Solved
Increased compression set after curing in the injection molding of liquid silicones
Rapid leaching of lubricants in injection molding applications
Lack of self-lubricating properties for silicone elastomers
Increased cost due to incorporating mold release additives
Applications
