Material Description: Silicone rubbers are widely used in industry and there are multiple formulations. Silicone rubbers are often one or two part polymers, and may contain fillers to improve properties or reduce cost. Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from -55 °C to +300 °C while still maintaining its useful properties. Due to these properties and its ease of manufacturing and shaping, silicone rubber is used in silicone gaskets, seals and orings and can be found in a wide variety of products such as:
Key Use(s): Static seals in extreme temperature situations. Seals for medical devices, compatible with FDA regulations.
Standard Compound: -85° to +400°F
Hardness (Shore A): 20 to 90
Features: Phenyl (PVMQ) based silicones can perform to -85°F. New polymers can take short term to 600°F.
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.
Test Method:With reference to US FDA 21 CFR 177.2600.
