In EVM and FEPM, the Type II coagent produced higher delta torque than the Type I coagents.
Meth)acrylate esters have not been shown to be as effective in FEPM grades.
in contrast, the FEPM grade is an alternating copolymer of tetrafluoroethylerie and propylene with a cure site added to the polymer.

FEPM was compounded using proprietary in-house technology.
FEPM reaches equilibrium after the same time period (7.
FEPM is beginning to stabilize after 504 hours and remains at a virtual plateau through 4,000 hours of aging (2.
Testing of FKM was discontinued after 168 hours while the FEPM reaches a plateau after approximately 500 hours and remains nearly flat through 4,000 hours (6.
