Temperature Resistance of ZruElast® FPM
Fluoropolymers in general feature excellent heat resistance. ZruElast FPM retains its elastic properties even at a continuous operating temperature of 200° C. When talking about temperature resistance, it has to be considered for how long materials are exposed to heat or elevated temperatures.
The figure below shows the relation between
operating temperature and hours of use. Besides the ability to withstand
short blasts of more than 300° C, laboratory tests have confirmed that
products made of ZruElast FPM still remained soft and elastic even after
ageing in a heat cabinet over a period of three years at a temperature of
190° C. If you compare these values with the performance of other elastomers
they seem even more significant. Nitrile rubber (NBR), for example, usefully
serves only up to a continuous maximum temperature of 120° C.
Similar in temperature performance are the materials chloroprene (CR) and
chlorosulfonated polyethylene. Aged at a temperature of 200° C, products
made of these materials would become brittle only after a few hours.
