INtbroction
DONPPANEL 412 PolyPound Polyols ndeye yakaenzana nePolyether Polyols, Surchals, CATLYSTS uye murazvo unodzoreredza muyero yakakosha. Iyo foam ine yakanaka yekudzivirira insulation zvinhu, mwenje uremu, yakakwirira kumanikidza simba uye murazvo unodzoreredza uye zvimwe zvakanakira. Iyo inoshandiswa zvakanyanya kugadzira mahwendefa eSandwich, anenge achiora mahwendefa, izvo zvinoshanda kuita zvitoro zvekutonhora, makabati, zvigaro zvekutamba uye zvichingodaro.
