GABATARWA
DonFoam 824 / Pir ne wani nau'i ne na saje polyols amfani hfc-245fa foaming wakili, da polyol matsayin babban albarkatun kasa, gauraye da musamman karin wakili, m ga rufi na yi, sufuri, harsashi da kuma sauran kayayyakin. Wannan abu aka gina shi musamman domin ci gaba da layi .An polyurethane samfurin shirya ta maida martani da shi tare da isocyanate yana da wadannan abũbuwan amfãni:
- Eco-friendly, ba tare da lalata lemar sararin samaniya Layer
- High compressive ƙarfi da kyau homogeneity na isotropic ƙarfi
- Excellent thermal rufi yi da kuma girma da kwanciyar hankali
