CTPB Carboxyl-Terminated Polybutadiene CAS 586976-24-1
Carboxyl-terminated kua polybutadiene roj hmab feem ntau hu ua CTPB luv luv. Rau muaj carboxyl ntawm ob qho kawg ntawm lub polymeric molecule, lub polymer no yog nyob rau hauv lub structurization nyob rau hauv lub carboxyl pab pawg neeg, kev faib ntawm lub network yog zoo huv si thiab tsis muaj free davhlau ya nyob twg. yog li nws muaj kev ua haujlwm zoo heev.
Cov khoom siv tsis tsuas yog siv tau rau hauv cov khoom siv foob pob hluav taws, tab sis kuj tuaj yeem siv rau hauv elastomers, adhesives, sealing khoom, epoxy resin hloov kho thiab cov khoom siv hluav taws xob.
Ntim hauv 50kg / nruas, 180kg / nruas, Lub sijhawm cia yog 1 xyoos.
Cov lus qhia kev nyab xeeb:
Kev khaws cia yuav tsum yog qhov txias, qhuav thiab ventilate. Qhov zoo tshaj plaws mob yog ntawm -20 ~ 38 ℃. Txee lub neej ntawm 12 lub hlis, yog tias tas sij hawm, tseem siv yog tias mus txog tus qauv los ntawm kev rov kuaj dua. Thaum kev thauj mus los yuav tsum tsis txhob los nag, tshav ntuj. Tsis txhob sib tov nrog oxidizer muaj zog.
