Product Code:SAE AMS3202
Title:Butadiene Acrylonitrile (NBR) Rubber, Dry Heat Resistant, 55 - 65
Issuing Committee:Ams Ce Elastomers Committee
Scope:This specification covers a nitrile (NBR) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes.These products have been typically used for parts, such as packings, bushings, grommets, and seals, requiring resistance to dry heat, but usage is not limited to such applications. Each application should be considered individually.
