Type of synthetic rubber used in tyres and other components.
A rubber material produced by copolymerizing isobutylene with a small amount of isoprene. Butyl is variously manufactured into sheet goods, blended with other rubber materials, and is often used to make sealants and adhesives.
A co-polymer of iso-butylene and isoprene.
An adhesive used in earlier model vehicles for glass retention. It is a petroleum product that requires no curing or hardening. Butyl is available in rolls of approximately 15 feet.
Type of non-curing and non-skinning sealant made from butylene. Usually used for internal applications.
Polyisobutylene is a hot melt sealant and is used as the primary seal for dual seal systems.
A synthetic rubber material that offers the highest permeation resistance to gas and water vapors. Especially suited for use with esters and ketones.
(chemical identification:isobutylene isoprene-IIR):is produced by copolymerizing isobutylene with small amounts of isoprene. These rubbers have excellent impermeability to gases, outstanding dielectric properties, good resistance to tearing, good aging properties at elevated temperatures and good chemical stability.
Synthetic rubber or man-made rubber. Invented during the 1950's for use in everything from car tires to chemical warfare suits. Considered a durable fabric, it has good barrier to a limited number of chemicals. Go to top
Copolymer of isobutylene and isoprene. (Commonly used fur loner tubes.)
A hydrocarbon radical, C4H9. Butyl has a rubber-like consistency, is formed from the copolymerization of isobutylene and isoprene and is used primarily in sealants and adhesives.
A rubber material that seals the glass to the spacer, creating an airtight and watertight IG unit. Butyl has the lowest gas permeability of all rubbers.
A rubber material that seals the glass to the spacer, creating an airtight and water-tight insulated glass unit.
Isobutylene - Isoprene Rubber, Low Rebound, Motor Mounts, Low Gas Permeability, Limited Heat and Oil Resistance. ASTM Designation IIR
rubber-like material produced by copolymerizing isobutylene with a small amount of isoprene. Butyl may be manufactured in sheets, or blended with other elastomeric materials to make sealants and adhesives.
Shortened term for polyisobutylene. The primary seal of an insulating unit and key component in restricting moisture vapor transmission.
An organic compound, used in the door business as a sealant. It is naturally black, and is heated and pumped through nozzles, or pumped cold.
In organic chemistry, butyl is a four-carbon alkyl substituent with chemical formula -C4H9 . It is derived from either of the two isomers of the alkane called butane.
