Epdm Rubber (ethylene Procylene Diene Monomer Rubber) imhando yeiyo synthetic rabha iyo inoshandiswa mune akawanda mashandisirwo. Dienes anoshandiswa mugadziri weEpdm rubber ndiEthyelidene 4-8% yeava vaionga vanowanzo shandiswa. Epdm ndeye m-kirasi rabber pasi peASTM Standard D-1418; Iyo m kirasi inobatanidza elastromers ine cheni yakakwana yeiyo polyethyle mhando (iyo m inowana kubva pane yakajeka izwi rePolethyle). EPDM inogadzirwa kubva kuEndylene, procylene, uye dione comonomer iyo inogonesa kuyambuka kuburikidza nekuvhara vulcanization. Iyo yekutanga hama ndeye EPR, Ethylene Procalene Rubber (Inoshanda kune yakakwirira-vemagetsi magetsi), iyo haina kubva kune chero dicurs precurss uye inogona kungoyambuka uchishandisa nzira dzakakura senge mapundu.
Sezvineiwo nevazhinji vaburi, EPDM nguva dzose inogara ichishandiswa nemabhuruku akadai seCarbon dema uye calcium carbonate, ine mapurasitiki akadai seyemafuta emahara, uye ane zvivakwa zveRubabha chete chete kana croster Kuyambuka kazhinji kunoitika kuburikidza neVulcanisation nesarufa, asi zvakare yakaitwa ne peroxides (yekukanganisa kupokana nekupesana) kana nenhengo dzinopesana. Yakakwirira-simba radiation yakadai sekubva kune emagetsi matanda dzimwe nguva inoshandiswa kugadzira mapuranga uye waya uye tambo.
