1. Ua ntej tshaj plaws, nws tiv taus cov laus thiab muaj dej ntau dhau. EPDM muaj kev tiv thaiv huab cua zoo tshaj plaws, nws tsis kam ua rau huab cua, tiv thaiv cov kua qaub thiab alkali, thiab tom qab so hauv dej kub ntawm 125 ° C rau 15 lub hlis, cov khoom kho tshuab hloov me ntsis thiab qhov ntim muaj ntau qhov kev nthuav dav tsuas yog 0.3%. Da dej hose yuav tsum tau siv cov dej kub kom ntev, yog li EPDM yog cov khoom siv zoo tshaj plaws.
2. Qhov thib ob yog elasticity. Peb txhua tus paub tias thaum siv tes da dej, peb yuav tsum ncab tas li kom ntxuav lub cev. EPDM molecular saw tuaj yeem tswj hwm kev ua raws ntau yam thiab tuaj yeem khaws cia nyob hauv qhov chaw qis, yog li qhov no kuj yog tus tsim. Ib ntawm cov kev hloov kho ua ntej rau EPDM.
