Description

Apart from FEP-coatings, COG offers
\u9664\u4e86FEP\u6d82\u5c42\uff0cCOG\u63d0\u4f9b
PFA-coatings as well. PFA stands for
PFA\u6d82\u5c42\u4ee5\u53ca\u3002PFA\u7684\u4ee3\u8868
perfluoralkoxy. PFA is used the same
\u5168\u6c1f\u70f7\u6c27\u57fa\u3002PFA\u662f\u76f8\u540c\u7684
way like FEP for the coating of FKM or
\u50cf\u5bf9\u6c1f\u6d82\u6599\u6216FEP
silicone O-rings. The PFA-material has
\u7845\u80f6O\u578b\u5708\u3002PFA\u6750\u6599\u5177\u6709
almost the same chemical resistance

O-rings can be exposed
O\u578b\u5bc6\u5c01\u5708\u53ef\u4ee5\u66b4\u9732
to higher working temperatures than

FEP-encapsulated O-rings and this with
FEP\u5305\u8986O\u578b\u5708\u548c\u8fd9
the same low-temperature flexibility. The
