FKM (Terpolymer) fluoroelastomer Gum-246
ʻO ka Fluoroelastomer FKM Terpolymer Gum-246 ka terpolymer o vinylidenefluoride, tetrafluoroethylene a me ka hexafluoropropylene. no ka manawa lōʻihi, ma 320 ℃ no ka manawa pōkole. ʻOi aku ka maikaʻi o ka waiwai o ka aila anti a me ka anti acid ma mua o FKM-26, ke kūʻē o FKM246 i ka aila, ozone, radiation, uila a me ka flamer like me FKM26.

Hoʻohana Huahana
Hoʻohana nui ʻia ka FKM246 i nā kaʻa, mīkini, petrochemical, a me nā ʻano ʻē aʻe. a i ʻole nā mea hoʻopaʻa paʻa i ka corrosion, i hana ʻia me nā paipu no ka lawe ʻana i nā solvents a i ʻole nā mea media ʻē aʻe, e like me ka corrosion.
Nānā
1. Fluoroelastomer terpolymer rubber i ka wela wela ma lalo o 200 ℃. E hoʻohua i ka trace decomposition inā hoʻokomo ʻia ma 200-300'C no ka manawa lōʻihi, a ʻo kona wikiwiki decomposing accelerates ma luna o 320 ℃, nā huahana decomposition ka nui o ka hydrogen fluoride. a me ka fluorocarbon organic compound.When raw fluorous rubber encounters fire, it will release toxic hydrogen fluoride and fluorocarbon organic compound.
2. ʻAʻole hiki ke hui pū ʻia ka FKM me ka pauka metala e like me ka pauka aluminika a me ka pauka magnesium, a i ʻole ma luna o 10% amine pūhui, inā e hiki mai, e piʻi ka mahana a e hoʻopili kekahi mau mea me FKM, e hōʻino i nā lako a me nā mea hana.
Pūʻolo, Kaʻa a me ka waiho ʻana
1.FKM ua paʻa i loko o ka PE plastic eke, a laila, hoʻouka i loko o cartons, ka upena kaumaha o kela carton he 20kg.
Mālama ʻia ʻo 2.FKM i loko o kahi hale kūʻai maʻemaʻe, maloʻo a me ka ʻoluʻolu. Lawe ʻia ʻo ia e like me nā kemika non-hazardous, a pono e hoʻokaʻawale i ke kumu pollution, ka lā a me ka wai i ka wā o ka lawe ʻana.
