Arizona Sealing Devices, Inc. Compound Designation: S
Standard Color: Red
Description: LSR is a low viscosity silicone elastomer intended for use in liquid injection molding (LIM) equipment. It offers high thermal stability and flexibility at low temperatures, high transparency and is easily colored. Also, self-lubricated and electrically conductive grades are available as well as FDA, ISO 10993 and Class VI medical compliant grades. Liquid silicone rubber is widely used to mold complex profiles because of its excellent flow characteristics.
- Static seals in extreme temperature situations.
- Environmental housing seals. Seals for medical devices.
- Complex profiles and high volume productions due to reduced cycle times.
Standard Compound: -85° to +400°F
Special Compound: -148° to +400°F
Hardness (Shore A): 10 to 80
Features: Silicone oil impregnated, allows for self-lubrication material.
Limitations: Generally, low abrasion and tear resistance, and high friction characteristics preclude silicones from effectively sealing some dynamic applications. Silicones are also highly permeable to gases and are generally not recommended for exposure to ketones (MEK, acetone) or concentrated acids.
