Donpipe 322 HCFC-141b base musanganiswa polyols pombi shell
ISUMO
DonPipe 322 imhando yekusanganisa polyols ine hcfc-141b seanopupuma agent, ichitora polyol seyakanyanya mbishi zvinhu, ichisanganisa neyakakosha mubatsiri.Ichi chinyorwa chinokodzera kunze kwemafuta ekuvharisa magomba ayo anoshandiswa pamvura, mafuta uye gasi pombi .Chigadzirwa che polyurethane chakagadzirwa nekuchigadzirisa ne isocyanate chine zvinotevera zvakanakira:
-- yakanaka yekumanikidza simba uye dimensional kugadzikana
-- yakakwira yepedyo-sero mwero uye yakanaka isina mvura kuita
-- yakanaka insulation performance
