Butyl rubber - Wikipedia
Butyl rubber, sometimes just called "butyl", is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as "PIB" or polyisobutene, (C 4 H 8) n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is based.
Butyl rubber (IIR) | Britannica
butyl rubber (IIR), a synthetic rubber produced by copolymerizing isobutylene with small amounts of isoprene. Valued for its chemical inertness, impermeability to gases, and weatherability, butyl rubber is employed in the inner linings of automobile tires and in other specialty applications.
Material Breakdown: What is Butyl Rubber?
2023年8月25日 · Butyl rubber has the distinction of being the only rubber material that is truly impermeable to both air and gas. While others may drastically limit airflow, butyl can completely prevent gas and oxygen from passing through a part.
All About Butyl Rubber - Properties, Applications, and Uses
2023年7月13日 · Butyl rubber is the only known elastomer that is impervious to gases. The material is flexible, with good room temperature damping characteristics. The material is biocompatible, resists many acidic and alkaline chemicals, ozone, heat, and weathering, and has good aging properties.
Polyisobutylene | Formula, Properties & Application
Polyisobutylene (PIB), often referred to as butyl rubber, is an interesting and important synthetic elastomer. Exhibiting unique characteristics such as impermeability to gas, exceptional resistance to heat, acids, alkalis, and ozone, PIB is broadly utilized in several industries.

Properties of Butyl Rubber (IIR) - Matmake
Butyl rubber is a synthetic rubber that is derived from isobutylene and a small amount of isoprene. It is known for its excellent impermeability to gases and liquids, making it a popular choice for applications where airtight seals or resistance to moisture and chemicals is required.
Butyl Rubber Products | Rubber Materials - QUALIFORM, INC.
What is Butyl Rubber? Butyl rubber, also known as isobutylene-isoprene rubber (IIR), is a versatile synthetic rubber that serves as a copolymer of isobutylene and isoprene. This rubber is created through the polymerization of approximately 98% isobutylene with 2% isoprene.
Butyl rubber - chemeurope.com
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.
Butyl Rubber | DLR Elastomer Guide To IIR – Butyl Rubber
Butyl rubber, also known as Isobutylene – Isoprene (IIR), is a synthetic rubber developed in the 1940s. IIR has exceptionally low gas permeability, making it ideal for inner tubes and high pressure/vacuum sealing applications.
