I-Fluoroelastomer Base Polymer Yenhloso Ejwayelekile
Isampula Yesitoko Imahhala Futhi Iyatholakala
I-Viton FKM raw gum iyizinto zokwakha ezenziwe ngerabha ye-viton. Sihlinzeka nge-Viton FKM raw gum esezingeni eliphezulu yaseShayina okuhlanganisa i-Low Mooney, i-Middle Mooney kanye ne-high Mooney grades.
I-FD26 serial FKM raw gum uhlobo olulodwa lwe-copolymer olwakhiwe nge-vinylidene fluoride (VDF) kanye ne-hexafluoropropylene (HFP). Luhlobo olujwayelekile lwe-FKM olubonisa ukusebenza okuhle kakhulu. Ungathola izakhiwo ezijwayelekile zezinto ezikuthebula elingezansi.

I-FD24 serial FKM raw gum uhlobo olulodwa lwe-terpolymer olwakhiwe yi-vinylidene fluoride (VDF), i-hexafluoropropylene (HFP) kanye ne-tetrafluoroethylene (TFE). Ama-Terpolymer anokuqukethwe okuphezulu kwe-fluorine uma kuqhathaniswa nama-copolymer (ngokuvamile aphakathi kuka-68 no-69% wesisindo se-fluorine), okuyinto
kuphumela ekumelaneni okungcono kwamakhemikhali nokushisa. Ungathola izakhiwo ezijwayelekile zezinto ezikuthebula elingezansi.

Iphakheji kanye nesitoreji
I-Fluoroelastomer ivalwa kuqala ngesikhwama se-PE - isisindo sayo singama-5kg ngesikhwama, bese ifakwa ebhokisini lebhokisi. Isisindo esiphelele ngebhokisi: 25kg
I-fluoreolastomer kufanele igcinwe endaweni epholile, eyomile futhi enomoya. Isikhathi sokuphila seshelufu izinyanga ezingama-24 kusukela ngosuku lokukhiqiza.
