TFE Propylene Oring
AFLAS
Shore A Description:
The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion resistance and resistance to extrusion.
60 Shore A is softer than 70
70 Shore A is the standard
90 Short A is very stiff
Specs:
Unique due to its resistance to petroleum products, steam, phosphate esters and brake fluids. In some respects it exhibits media compatibility properties similar to ethylene propylene and fluorocarbon. Fair resistance to brake fluids and phosphate esters while exhibiting good resistance to petroleum oils.
Material:
AFLAS (TFE Propylene)
Standard Service Temperature: -20°F - +400°F
Application:
Peroleum Fluids: Steam, Amines, Brake Fluids, and Phosphate Esters
This material is finding interest for seal applications requiring petroleum resistance, steam, and amine resistance such as those applications encountered in the petroleum industry. Additional interest is being generated in applications requiring petroleum and brake fluid resistance or petroleum and phosphate ester resistance.
