Butyl Adhesives, Butyl Tapes

Butyl Tapes, are used in many applications. The advantage of using butyl rubber in an adhesive format is that it is malleable and impermeable to air and water. It is hard wearing, can be applied to a wide variety of carrier surfaces and is able to be easily applied, thus giving instant results.
Uses in so many industries from providing waterproof joining solutions for sythetic turf and water sealing tarpaulins for dams and pondliners, to waterproofing and joining applications for piping, roof flashing, corrugated iron and shower bases, means butyl adhesive tape has a wide variety of uses.

Butyl Adhesives, are made from Butyl rubber which 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, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is based.
Butyl rubber 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. Polyisobutylene is a colorless to light yellow viscoelastic material. It is generally odorless and tasteless, though it may exhibit a slight characteristic odor. Butyl rubber has excellent impermeability, and the long polyisobutylene segments of its polymer chains give it good flex properties. It can be made from the monomer isobutylene or CH2=C(CH3)2 only via cationic addition polymerization.

A synthetic rubber, or elastomer, butyl rubber is impermeable to air and used in many applications requiring an airtight rubber seal. Polyisobutylene and butyl rubber are used in the manufacture of adhesives, agricultural chemicals, fiber optic compounds, ball bladders, caulks and sealants, cling film, electrical fluids, lubricants (2 cycle engine oil), paper and pulp, personal care products, pigment concentrates, for rubber and polymer modification, for protecting and sealing certain equipment for use in areas where chemical weapons are present, as a gasoline/diesel fuel additive, and even in chewing gum. The first major application of butyl rubber was tire inner tubes. This remains an important segment of its market even today.
