Polybutene CAS 9003-28-5 yog dab tsi?

Polybutylene muaj kev tiv taus kub zoo. Tiv taus cov tshuaj xeb hauv cov roj, cov tshuaj ntxuav thiab lwm yam kuab tshuaj, tsis tsim cov embrittlement zoo li lwm cov yas xws li HDPE. Embrittlement tsuas yog tshwm sim nyob rau hauv cov oxidants muaj zog xws li 98% concentrated sulfuric acid. Kev tiv taus creep zoo heev. Nws muaj kev tiv thaiv hnav zoo ib yam li ultra high molecular polyethylene. Polybutene yog ib qho polymer inert polymer, feem ntau yog ua los ntawm polymerization ntawm butene, yog ib qho polymer homopolymer. Piv nrog rau lwm cov polyolefins, nws yog rigid. Lub zog tensile siab.

Daim Ntawv Thov

Polybutylene feem ntau siv ua cov khoom siv yas, cov khoom sib txuas, cov tshuaj nruab nrab rau cov roj av ntxiv, thiab cov khoom siv foob. Txawm hais tias polybutylene tau pom tias txhim kho cov khoom xws li kev nplaum, kev tiv thaiv xeb thiab kev tiv thaiv dej hauv cov xim, nws kuj tseem siv rau hauv kev tsim cov tshuaj pleev ib ce xws li cov di ncauj pleev.
