Isobutylene Isoprene Rubber (IIR)
Isobutylene Isoprene Rubber (IIR) refers to isobutylene-isoprene copolymers with low unsaturation defined by the isoprene fraction. Polymer chemistry, molecular structure and compounding establish cure and service behaviour; finished-part performance requires the full formulation.

Product & engineering
Understand the product.
Isobutylene Isoprene Rubber, which is abbreviated as IIR, is a synthetic rubber, a copolymer of isobutylene with isoprene. Isobutylene Isoprene Rubber can also be called Butyl Rubber. The primary properties of Isobutylene Isoprene rubber are excellent air-barrier performance, good flex fatigue and vibration damping. From inner tubes to curing bladders, butyl properties are valued across a range of rubber products.
For this subject, the supplied object is isobutylene-isoprene copolymers with low unsaturation defined by the isoprene fraction. Compare monomer composition, molecular weight and cure system before finished hardness. Fillers, plasticisers and crosslink density alter compression set, swelling and low-temperature behaviour. A liquid reactive rubber is a formulation ingredient rather than a finished solid elastomer; assess the complete cured compound under the actual media and load conditions.
What turns activity into demand
Qualified formulations connect polymer content and process yield to accepted elastomer parts. Raw polymer, compound and converted-part demand must be tracked at their respective supply stages.
The commercial boundary
Polymer chemistry, cure and application are intersecting dimensions. Count raw elastomer or compounded material explicitly; finished seals or tyres cannot be added to polymer shipments without a material balance.
Why is the polymer name insufficient for a compound decision?
