Note:
PVDF resins have good thermostability at the temperature below 310℃. However, it will decompose into the toxic
hydrogen fluoride and fluorocarbon if it is idle for a long time at the temperature between 310～ 320℃. It is not suggested
to use PVDF resin at temperature higher than 370℃ because this will accelerate the decomposition velocity in such
an environment. Besides, please keep in mind that PVDF resin will release toxic hydrogen fluoride and fluorocarbon when it burns.
