Bromobutyl rubber | ExxonMobil Chemical
Exxon™ bromobutyl rubber is derived from halogenating butyl rubber with bromine in a continuous process. It is structurally similar to Exxon™ chlorobutyl rubber and produced through the same halogenation process.. Our bromobutyl rubber gradeslate offers a range of polymer viscosities and cure responses, reflecting adjustments in functionality and additives content.

IIR
IIR – Butyl Rubber (Isobutylene-isoprene Rubber) Properties. Butyl rubber, also known as Isobutylene-isoprene (IIR), is a synthetic elastomer produced by low temperature cationic copolymerization of 1,1-dimethylethylene (isobutylene) with about 0.5 to 2 percent 1-methyl-1-butenylene (isoprene) using Lewis catalysts in chlorocarbon solvents.

Chloroprene - an overview | ScienceDirect Topics
Chloroprene rubber (CR) possesses the following properties: good chemical resistance; high resistance to aging and ozone; low risk of glazing; better wear resistance than natural rubber (NR); higher cost than NR [10]. Chloroprene elastomers are rigid, usually soft
Send InquiryPolychloroprene
Chloroprene rubber typically displays good resistance to ozone cracking, heat aging and to chemical attack. For example, it has good resistance to many chlorofluorocarbons, aliphatic hydrocarbons, mineral oils, greases and ozone, but only moderate or poor resistance to acids, solvents, and fuels.
