DUPANEL 415 HFC-365MFC KOOB TSHUAB COLYOLS rau PUR
DUPANEL 415 HFC-365MFC KOOB TSHUAB COLYOLS rau PUR
INtroduction
Donpanel 415 yog ib hom kev sib xyaw polyet polyols nrog HFC-245FA raws li tus neeg sawv cev ua npuas dej, noj polyol raws li tus neeg sawv cev tseem ceeb thiab sib xyaw nrog tus neeg sawv cev tshwj xeeb. Nws yog qhov haum rau cov rwb thaiv tsev thermal ntawm lub tsev muag khoom, txias cia khoom pawg thawj coj thiab lwm yam khoom.Qhov khoom siv Polyurethane tau npaj los ntawm reacyanting nws nrog isocyanate muaj cov txiaj ntsig hauv qab no:
- tsis muaj tsev cog khoom nyhuv thiab tsis puas lub ozone txheej
- Zoo fluidity thiab cov khaub thuas ua npuas ncauj zoo nkauj
- Cov rwb thaiv tsev zoo heev, seem ruaj khov thiab cov nplaum
