BUTYL RUBBER WEBSITE
Tradeasia International Pte. Ltd is a privately owned, independent company headquartered in Singapore. Tradeasia International was first established in 2004 with the sole intention of carrying out chemical distribution services especially to commodity industries in many parts of the world.
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, (C4H8)n, 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 but has two methyl groups substituted on every other carbon atom, rather than one.
MANUFACTURING OF PROCESS
Like other rubbers, for most applications, butyl rubber must be compounded and vulcanized (chemically crosslinked) to yield useful, durable end use products. Grades of Butyl have been developed to meet specific processing and property needs, and a range of molecular weights, unsaturation, and cure rates are commercially available. Both the end use attributes and the processing equipment are important in determining the right grade of Butyl to use in a specific application. The selection and ratios of the proper fillers, processing aids, stabilizers, and curatives also play critical roles in both how the compound will process and how the end product will behave.
APPLICATION BUTYL RUBBER
Butyl Rubber Liquid
Concentrated solution of butyl rubber with special resins and reinforcing fillers that, once dried, forms a film adhered to the surface which is waterproof and with the necessary elasticity to adapt itself to the dilatation of the building materials.
Butyl gloves have a high permeation resistance to gases and water vapors and provide heavy chemical resistance to esters, ketones, and acids. Butyl is very elastic and remains flexible at low temperatures.
A rubber stopper is a small, tapered plug used to seal the openings of test tubes, flasks and other laboratory glassware. Stoppers made of cork are also available for this purpose. However, rubber stoppers are preferable for applications.
Adhesives are either natural or synthetic and come in three different types: acrylic-based, silicone-based and rubber-based. Butyl tape is a synthetic rubber adhesive manufactured to upgrade natural rubber adhesives.
