Donfoam 812PIR HCFC-141B base musanganiswa polyols yePIR block furo
NHUNGAMIDZO
DonFoam 812/PIR imhando yekusanganisa polyols ine hcfc-141b inopupuma furo, ine polyol seyakanyanya mbishi, yakasanganiswa neakakosha anobatsira mumiriri, akakodzera kuvharwa kwekuvaka, kutakura, goko uye zvimwe zvigadzirwa. Iyo polyurethane chigadzirwa chakagadzirwa ne kuita nayo ne isocyanate kune zvinotevera zvakanakira:
1.Foam ine simba rakafanana uye dimensional kugadzikana kumativi ose
2.Zvigadzirwa zvefoam zvinogona kutemwa mumhando dzakasiyana maererano nezvinodiwa zvechigadzirwa
3.Excellent thermal insulation performance
