EPDM vs PTFE
Rabadhka EPDM waxaa iska leh kala soocida termuusyada elastomers (caag), halka PTFE ay iska leedahay heerkulbeegyada.Fadlan ogow in labada walxood ay leeyihiin cufnaan aad u kala duwan.Rabadhka EPDM waa elastomer heerkulbeeg ah ama alaab caag ah.Waxay leedahay cufnaan si cadaalad ah u hooseeya iyo tan ugu sarreysaAkhri wax dheeraad ah -
