Common monomers used to make synthetic rubbers include Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR) and Butyl Rubber (IIR). Chemical agents are used to turn the individual polymers into polymer chains. This forms a rubber substance. In a process called vulcanisation, the rubber substance will be processed …

Chewing gum (when butyl is used in food-grade form) Butyl Rubber in Biotechnology. ILT is a global leader in manufactured septa seals and vial caps. Using butyl rubber provides uniform septa sealant that when married to PTFE in the molding process provides the clean surface barrier during sample analysis.
Any contact of butyl rubber with petroleum products (gasoline, oil, etc.) will rapidly degrade the protective effect of this material, and it should be immediately discarded. Nor should butyl rubber be used for insulation against electrical shock. Butyl rubber gloves usually come in three thicknesses: 0.007, 0.014, and 0.025 in.
Specialty chemicals company LANXESS has successfully concluded the pilot phase for a highly efficient production process for butyl rubber. The past seven years saw the company working on a fundamentally new technology for a more sustainable production. An important step in this process was the testing of the new technology in …
Vulcanization of rubber uses heat and sulfur (or another chemical) to form a hardened cross-linked polymer. Vulcanization or vulcanisation (British) is a process of hardening rubber using chemicals and (usually) heat. Originally, vulcanization described the treatment of natural latex rubber with heat and sulfur.While this remains the most …
Butyl is one of many types of synthetic rubber used to manufacture parts. Find out what makes butyl special and whether it's right for your needs.
Halogenated butyl rubbers include BIIR (brominated isobutyl isoprene rubber, bromobutyl rubber) and CIIR (chlorinated isobutyl isoprene rubber). Currently, ExxonMobil and LANXESS are the world's major producers of butyl rubber and halogenated butyl rubber. Butyl rubber is used mainly for tires, tubes, and tire products.

Butyl rubber—also known as polyisobutylene and PIB (C 4 H 8) n is a synthetic rubber, a homopolymer of 2-methyl-1-propene.Polyisobutylene is produced by polymerization of about 98% of isobutylene with about 2% of isoprene.Structurally, polyisobutylene resembles polypropylene, having two methyl groups substituted on every other carbon atom. It has …
The reaction rates are strongly affected by the polymerization conditions.

Conventional production of butyl rubber is highly complex, requiring process steps at very low temperatures and significant usage of steam. The new process, said Lanxess, is significantly more energy- and cost-efficient. Lanxess has been testing of the technology at two pilot plants at its production site in Zwijndrecht, Belgium since early 2012.
The earliest and most widespread use of butyl rubber was in tire inner tubes, a role it continues to fulfill today. While butyl rubber is highly versatile, it is not recommended for applications involving contact with petroleum oils. Read on for more information about the properties and advantages of butyl rubber:
conventional butyl rubber. EXPERIMENTAL SECTION The butyl rubber (from LANXESS Inc.) was a random copolymer of isobutylene and 7.0 mol % isoprene. Its number-average molecular weight was 150 kDa, with a polydispersity ∼4 and gel content less than 2%. For assessment of miscibility with the PIB, some IIR having lower …
Other Addition Polymers. PVC (polyvinyl chloride), which is found in plastic wrap, simulated leather, water pipes, and garden hoses, is formed from vinyl chloride (H 2 C=CHCl). The reaction is shown in the graphic on the left. Notice how every other carbon must have a chlorine attached. Polypropylene: The reaction to make polypropylene (H 2 C=CHCH 3) …
Such a reactor, because of its simple construction, possesses only two new factors that can affect the process (as compared to the process of butyl rubber synthesis in a volume reactor with a stirring device []), such as the reaction mass velocity v (in numerical experiments v = 1, 3, 6, and 10 m/s) and the diameter of the reactor d (in …

Butyl rubber is a copolymer of isobutylene and isoprene. Simple copolymers are known as "regular" or "clear" butyl rubber, or simply "butyl." When butyl rubbers are modified after polymerization with the halogens bromine or chlorine, a second family, known as halobutyl rubber (or halobutyls), results. The principal characteristic common to both …
