Product Code:SAE AMS3198
Title:Sponge, Chloroprene (CR) Rubber, Medium Stiffness
Issuing Committee:Ams Ce Elastomers Committee
Scope:This specification covers a chloroprene (CR) rubber sponge in the form of sheet, strip, molded shapes, or other forms, as ordered. These products have been used typically for general applications requiring the use of open-cell, medium sponge rubber pads and seals operating from -40 to +80 degrees C (-40 to +176 degrees F), but usage is not limited to such applications.
