Donpanel 412 HCFC-141b base blend polyols yePUR
ISUMO
DonPanel 412 blend polyols musanganiswa une polyether polyols, surfactants, catalysts uye flame retardant mune yakakosha reshiyo.Iyo furo ine yakanaka yekupisa yekudzivirira chivakwa, huremu huremu, yakakwirira compression simba uye murazvo wemoto uye zvimwe zvakanaka.Inoshandiswa zvakanyanya kugadzira sandwich plates, corrugated plates etc, iyo inoshanda kugadzira zvitoro zvinotonhora, makabati, anotakurika pekugara uye zvichingodaro.
