Donfoam 812 HCFC-141B tushe saje polyols for block kumfa
GABATARWA
Donfoam 812 saje polyether polyols amfani ga kayan Pur block kumfa. Kumfa yana da uniform cell, low thermal watsin, thermal rufi yi ne mai kyau, harshen wuta retardant yi ne mai kyau, low zazzabi ba ƙunci crack da dai sauransu
Yadu a yi amfani da tsari daga dukan nau'i na rufi aikin kamar: gina waje bango, sanyi ajiya, tankuna, manyan bututu da dai sauransu
