Polybutene CAS 9003-28-5 yog dab tsi?

Polybutylene muaj cov cua sov zoo. Cov tshuaj tiv thaiv corrosion hauv cov roj, cov tshuaj detergents thiab lwm cov kuab tshuaj, tsis tsim embrittlement zoo li lwm yam yas xws li HDPE. Embrittlement tshwm sim tsuas yog nyob rau hauv muaj zog oxidants xws li 98% concentrated sulfuric acid. Zoo heev creep kuj. Nws muaj tib yam hnav tsis kam zoo li ultra siab molecular polyethylene. Polybutene yog ib tug polymer inert polymer, feem ntau yog tsim los ntawm polymerization ntawm butene, yog ib tug polymer homopolymer. Piv nrog rau lwm cov polyolefins, nws yog nruj. Siab tensile zog.

Daim ntawv thov

Polybutylene feem ntau yog siv los ua plasticizer, binder, chemical intermediate rau roj av additives, thiab sealant. Txawm hais tias polybutylene tau pom los txhim kho cov khoom xws li adhesion, tiv thaiv xeb thiab dej tsis kam hauv cov xim, nws kuj yog siv feem ntau hauv kev tsim cov tshuaj pleev ib ce xws li lipsticks.
