Butyl rubber overview

butyl-rubber
What is a butyl rubber? During this time you may not realize had been taking and use of products made ​​from butyl rubber. Starting from the outer tire and inner tube for your vehicle, to household devices that you use every day.

Butyl rubber is a co-polymer produced from a combination of two different polymers: isobutylene and isoprene. Butyl rubber shows the main characteristics of outstanding impermeability to gases and very durable.

A synthetic rubber, or elastomer, butyl rubber is impermeable to air and used in many applications requiring an airtight rubber. 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. More about butyl rubber application here.

tire
Butyl Rubber applications in industries exist in everyday life include: industrial, automotive, construction, chemical protection, sports, etc.

Tire
The most common uses of butyl rubber is as base material for tire interliners and inner tubes. Butyl rubber known for superior air retention, strong and durable properties.

Automotive
Heat resistance, resistance to ozone, high damping, all of the barrier properties of butyl rubber make it ideal material for hoses, gaskets and automotive vibration control.

healthcare
In the pharmaceutical industry and medicine, butyl rubber is used as the main material for high-quality bottle stopper and a sterile barrier to gas or moisture.

Fuel and lubricant additives
Butyl rubber (polyisobutylene) was added in small quantities for engine lubricating oils used in the result of a significant reduction in the generation of oil mist and thereby reduce oil mist inhalation by the operator.
As a fuel additive, polyisobutylene has detergent properties. When added to diesel fuel, he refused to fouling of fuel injectors, leading to reduced hydrocarbon and particulate emissions.

It is mixed with detergents and other additives to make “detergent package” that is added to gasoline and diesel to resist deposit buildup and engine knock. Polyisobutylene used in some formulations as a thickening agent.

ball
Sporting equipment
The nature of butyl rubber which flexible, elastic and strong, enabling it to be used as the bladders in basketball, rugby balls, soccer balls and other inflatable balls to provide a tough air-tight inner compartment.

Gas masks and chemical protection agents
Because of its strong and able to withstand contamination, butyl rubber seal materials suitable for use in gas masks and protective clothing. Is in accordance with nature when exposed to agents such as NH3 (ammonia), butyl rubber will break down more slowly.
Butyl rubber as the elastomer is harder and less porous material which is stronger than other elastomers, such as natural rubber or silicone, but still enough elasticity to form an airtight seal.

Industrial
butyl rubbers used to improve formulations for reliable conveyor belts, tank linings and condenser packaging.

Adhesive & Sealing
Butyl rubber adhesive material has a low permeability, inherent tackiness and aging resistance. Widely used to repair the inner tube and tire also to glue some plastics.

Butyl rubber is water-resistant and never Actually cures or hardens completely, making it an extremely flexible sealant. It can withstand adverse weather conditions and is ideal for outdoor purposes, Such as sealing stone, wood or metal. Proper application of butyl rubber caulk Will determine its effectiveness.

Constructions
Butyl rubber added durability against weather for asphalt, contact cement and sealant tape.

Chewing gum
For the food industry, the food-grade butyl rubber is used as a base for various types of chewing gum in the market.
