General Purpose Fluoroelastomer Base Polymer
Viton FKM chingamu yaiwisi ndi zida za rabara ya viton.Timapereka chingamu chabwino kwambiri cha ku China cha Viton FKM yaiwisi kuphatikiza Low Mooney, Middle Mooney ndi magiredi apamwamba a Mooney.
FD26 seriyo FKM chingamu yaiwisi ndi mtundu umodzi wa copolymer wopangidwa ndi vinylidene fluoride (VDF) ndi hexafluoropropylene (HFP).Ndi mtundu wamba wa FKM wowonetsa magwiridwe antchito onse.Mutha kupeza zambiri zazomwe zili m'munsimu.

FD24 serial FKM yaiwisi chingamu ndi mtundu umodzi wa terpolymer wopangidwa ndi vinylidene fluoride (VDF), hexafluoropropylene (HFP) ndi tetrafluoroethylene (TFE).Ma Terpolymers ali ndi fluorine wambiri poyerekeza ndi ma copolymers (nthawi zambiri pakati pa 68 ndi 69 peresenti yolemera ya fluorine), yomwe

Phukusi ndi Kusunga
Fluoroelastomer amasindikizidwa koyamba mu PE bag-weights 5kgs pa thumba, kenaka amaikidwa mu bokosi la makatoni.Net kulemera pa bokosi: 25kgs
Fluoreolastomer iyenera kusungidwa pamalo ozizira, owuma komanso mpweya wabwino.Nthawi ya alumali ndi miyezi 24 kuyambira tsiku lopanga.
