Low molecular weight polyisobutene (PIB)yog hais txog polyisobutylene (PIB) nrog qhov sib txheeb molecular loj ntawm 350-35000. Nws yog xim tsis muaj xim, tsis muaj ntxhiab, tsis muaj tshuaj lom viscous kua lossis ib nrab ntawm cov khoom, nrog rau cov cua sov zoo, tiv thaiv oxygen, tiv thaiv ultraviolet, acid thiab alkali tsis kam thiab lwm yam tshuaj lom neeg.
Txoj kev npaj
Tsawg molecular hnyav polyisobutyleneyog npaj los ntawm homopolymerization ntawm isobutylene. Cov txheej txheem kev npaj sib txawv thiab cov txheej txheem txheej txheem yuav ua rau muaj kev hloov pauv hauv qhov hnyav molecular. Tsawg molecular hnyav polyisobutylene feem ntau tau los ntawm kev tswj cov xwm txheej ntawm cov tshuaj tiv thaiv polymerization.
Application of Low molecular weight polyisobutylene PIB
Tsawg molecular hnyav polyisobutyleneyog dav siv nyob rau hauv ntau lub teb:
1. Lubricants thiab lawv cov additives
2. Cov khoom siv hluav taws xob insulating
3. Adhesives thiab sealants
4. Kev sib xyaw ntawm lwm cov polymers: Hauv cov khoom siv polymers xws li roj hmab, tsis tshua muaj molecular hnyav polyisobutylene yog siv los txhim kho kev laus thiab kev cuam tshuam ntawm cov khoom.
