CTPB Carboxyl-kare polybutadiene(CTPB) CAS 586976-24-1
CTPB shine roba polybutadiene ruwa tare da ƙungiyoyin carboxyl a duka ƙarshen kwayoyin halitta, wanda ke da kyakkyawan juriya da elasticity na sanyi.
A CTPB yafi amfani da matsayin toughening wakili ga epoxy guduro adhesives da sealants, shi kuma za a iya amfani da dabam domin masana'antu sealing kayan, adhesives, coatings, na roba zaruruwa, da wucin gadi kayan Fata, roba modifiers, da dai sauransu.
Kamar yadda mai faɗakarwa
Kunshe a cikin 50kg / drum, 170kg / drum, Lokacin ajiya shine shekara 1.
Umarnin aminci:
Ma'aji ya kamata ya kasance a sanyi, bushe da iska. Mafi kyawun yanayin shine tsakanin -20 ~ 38 ℃. Rayuwar tanadin watanni 12, idan ya ƙare, har yanzu ana amfani da ita idan har ta kai ta hanyar sake gwadawa. Lokacin da sufuri ya kamata ya guje wa ruwan sama, hasken rana. Kada ku haɗu tare da mai ƙarfi oxidizer.
