Isticmaalka
Polyisobutene (hydrogenated) waa walax sunta ka saarta.
Polyisobutylene, oo mararka qaar loo yaqaan butyl rubber, mararka kalena PIB, waa polymer vinyl ah. Aad ayuu ugu eg yahay polyethylene iyo polypropylene qaab-dhismeedka, marka laga reebo in kaarboon kasta oo kale lagu beddelo laba kooxood oo methyl ah. Waxaa laga sameeyay isobutylene monomer, iyadoo la adeegsanayo polymerization vinyl cationic.
Polyisobutylene waa caag macmal ah, ama elastomer. Waa mid gaar ah sababtoo ah waa caagga kaliya ee gaaska aan ku dhex milmi karin. Taasi waa, waa caagga kaliya ee hawo hayn kara muddo dheer. Waxaa laga yaabaa inaad dareentay in buufintu ay simbiriirixan doonaan dhowr maalmood ka dib. Tani waa sababta oo ah waxay ka samaysan yihiin polyisoprene, kaas oo aan gaaska ku dhex milmi karin. Sababtoo ah polyisobutylene waxay qaban doontaa hawada, waxaa loo isticmaalaa in lagu sameeyo waxyaabo sida tuubooyinka gudaha, lakabka taayirada, iyo lakabka gudaha ee kubbadda kolayga.
