Polytetrafluoroethylene elastic band ne mai kyau hatimi kayan. Yana da tsabta polytetrafluoroethylene rarraba resin, ta hanyar matsa lamba bar, high zafin jiki yanka, yana da low friction coefficient, sinadarai lalata juriya, sealability mai kyau, ba hydrolysis, ba hardening da sauransu amfani, shi za a iya amfani da shi a -160 ° C - + 280 ° C zafin jiki, dace da reactor, mota janareta da kuma daban-daban nau'ikan baki tanks, ganga hatimi.
