12000 tons/year of low molecular weight polyisobutene is a self-developed project of our company, which has been validated from small-scale, pilot scale, to industrial production. We can independently switch and produce various grades such as 950, 1300, 2400 according to customer needs and market demand. Low molecular weight polyisobutene produced by isobutene solution polymerization is a colorless, transparent or light yellow viscous liquid, non-toxic and odorless.
