Donpanel 415 HFC-365mfc isi ngwakọta polyols maka Pua
m NTRODUCTION
DonPanel 415 bụ ụdị ngwakọta polyether polyols na HFC-245fa dị ka na-asụ ụfụfụ gị n'ụlọnga, na-ewere polyol dị ka isi akụrụngwa na weere na pụrụ iche inyeaka n'ụlọnga. O kwesịrị ekwesị ka thermal mkpuchi nke ewu mbadamba, oyi nchekwa mbadamba na ndị ọzọ na products.The polyurethane ngwaahịa na-akwadebe site omume ya isocyanate nwere ndị na-esonụ uru:
- No griin haus mmetụta na-adịghị imebi ozone Layer
- Ezi fluidity na edo ụfụfụ njupụta
- Ezigbo mkpuchi, akụkụ nkwụsi ike na adhesion
