Description

Modern FKM (FPM \/ fluoroelastomer) sealing compounds can be used today in
\u73b0\u4ee3\u6a61\u80f6\uff08FPM \/\u6c1f\u6a61\u80f6\uff09\u5bc6\u5c01\u5316\u5408\u7269\u53ef\u4ee5\u7528\u5728\u4eca\u5929
situations where they are exposed to many different kinds of aggressive media.

But hardly any operating medium subjects elastomer seals to such problems as

While it has generally been true in the past to say that FKM does not offer
