Sealing O Ring EPDM Material High Abrasion Resistance For Heavy Machinery
Standard Compound: -85° to +400°F
Hardness (Shore A): 40 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.
In the Silicone family, you will find compounds which are superior as static seals in extreme temperature conditions. Standard compounds handle operating temperatures -85º to +400ºF. Silicone compounds are popular in food and medical applications because they are very clean and do not impart odor or taste.
Special Phenyl silicones can be used down to -148°F.
EPDM is a copolymer of ethylene and propylene. Ethylenepropylene-diene rubber (EPDM) is produced using a third monomer and is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base.
Both o-rings and gaskets can be made from EPDM materials.
