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:

• Automotive applications
• Many cooking, baking, and food storage products
• Apparel including undergarments, sportswear, and footwear
• Electronics equipment
• Home repair and hardware
• A host of unseen applications.

Silicone’s temperature tolerance maintains a lack of brittleness below freezing and excellent tolerance of temperatures in excess of 150 °C (302 °F).

Silicone o rings, gaskets and seals are Resistant To: High/Dry Heat, Fungus, Sunlight, Ozone, and Weathering.

Do not use with: Fuels, silicone, and petroleum based oils, acids

ASTM D1418 Designation: MQ, PMQ, VMQ, PVMQ

ASTM D2000/SAE J200 Type, Class: FC, FE, GE

Apple Compound Designation: SL

Standard Color: Red

Key Use(s): Static seals in extreme temperature situations. Seals for medical devices, compatible with FDA regulations.

Temperature Range:
Standard Compound: -40° to +220°C

Hardness (Shore A): 10 to 85

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) or concentrated acids.
