DUCPANEL 412 HCFC-141B Lub Hauv Paus Kev Polyols rau Pur
INtroduction
Donpanel 412 Kev sib xyaw polyols yog qhov sib xyaw uas muaj polyether polyols, surfactants thiab nplaim retardant nyob rau hauv ib qho tshwj xeeb. Tus npaus muaj cov khoom nruab nrab zoo thermal, lub teeb nyob rau hauv qhov hnyav, siab compression lub zog thiab nplaim retardant thiab lwm yam zoo. Nws yog dav siv los tsim qhaandwich daim hlau, corrugated phaj thiab lwm yam, uas siv los ua cov khw muag khoom txias, chaw khaws khoom noj thiab cov khoom siv tau ua ntej.
