O-Ring Material Selection Guide

  • Standard CompoundSpecial Compound

Rubber compounds are a mixture of polymers, fillers, anti-oxitives and curatives. Various combinations can improve specific properties. Special compounds can be made to broaden temperature range or improve fluid resistance. These may add to lead time, but can lead to better application performance.

TFE/P™

Material Selection Guide

Aflas®

Trade Names:

  • Aflas® . . . Asahi Glass Co., Ltd.

ASTM D1418 Designation: FEPM

ASTM D2000/SAE J200 Type, Class: HK

Apple Compound Designation: AF

Standard Color: Black

Description: A copolymer of tetrafluoroethylene/ propylene, TFE/P can offer a combination of high temperature and chemical resistance.

Key Use(s): Seals for oil field, aerospace, chemical and general industrial environments.

Temperature Range: Standard Compound: -14° to +446°F.

Hardness (Shore A): 60 to 90.

Features: Resistance to a wide range of chemicals, high temperature and electrical capabilities give broad application diversity. TFE/P have resistance to acids and bases, steam/hot water, corrosion inhibitors, oils and lubricants, and industrial solvents. TFE/P also offer improved low temperature properties over most fluoroelastomers.

Limitations: Tests have shown that other FKM elastomers are recommended for automotive fuels since they have less volume swell than TFE/P. Also, TFE/P has shown to have less than desirable results when exposed to toluene, ethers, ketones, and acetic acid.

This tool is meant to be used as a professional guide only. Because no two situations or installations are the same, these comments, suggestions, and recommendations are necessarily general and should not be relied upon by any purchaser without independent verification based on the particular installation or use. We strongly recommend that the seal you select be rigorously tested in the actual application prior to production use.
