Ethylene propylene (EPDM)

Nqe lus piav qhia: Lub copolymer ntawm ethylene thiab propylene (EPR), ua ke nrog peb lub comonomer adiene (EPDM), Ethylene Propylene tau txais kev lag luam dav dav rau nws cov ozone zoo heev thiab cov yam ntxwv tsis zoo.

Kev siv tseem ceeb: siv sab nraum zoov tiv thaiv huab cua.Automotive nres systems.Tsheb cua txias tshuab.Kev siv dej.Tsawg torque tsav siv.

Qhov kub thiab txias
Standard Compound: -40 ° txog +275 ° F
Qhov Chaw Tshwj Xeeb: -67 ° txog +302 ° F

Hardness (Shore A): 40 txog 95

Nta: Thaum sib xyaw siv cov tshuaj peroxide curing cov kev pabcuam kub tuaj yeem ncav cuag +350 ° F.Kev tiv thaiv zoo rau cov kua qaub thiab cov kuab tshuaj (xws li MEK thiab Acetone).

Kev txwv: Tsis muaj kev tiv thaiv rau hydrocarbon kua.

EPDM muaj qhov ua tau zoo rau cov cua sov, dej thiab chav dej, alkali, me ntsis acidic thiab oxygenated cov kuab tshuaj, ozone, thiab tshav ntuj (-40ºF txog +275ºF);tab sis nws tsis pom zoo rau roj av, roj av roj thiab roj, thiab hydrocarbon ib puag ncig.Qhov nrov roj hmab sib xyaw no feem ntau yog thawj qhov kev xaiv rau kev siv qis torque tsav siv.
