Synthetic Rubber
Synthetic rubber is any type of artificially made polymer material which acts as an elastomer. It can undergo much more elastic deformation under stress than most materials and still return to its previous size without permanent deformation. Synthetic rubber serves as a substitute for natural rubber in many cases, especially when improved material properties are needed. It is now an essential component in tyres manufacturing.
Styrene Butadiene Rubber (SBR)
SBR is predominantly used for the production of car and light truck tires and truck tire retread compounds. A complete list of the uses of SBR includes houseware mats, drain board trays, shoe sole and heels, chewing gum, food container sealants, tires, conveyor belts, sponge articles, adhesives and caulks, automobile mats, brake and clutch pads, hose, V- belts, flooring, military tank pads, hard rubber battery box cases, extruded gaskets, rubber toys, moulded rubber goods, shoe soling, cable insulation and jacketing, pharmaceutical, surgical, and sanitary products, food packaging, etc.
Poly Butadiene
Poly Butadiene is a synthetic rubber that has a high resistance to wear and is used especially in the manufacture of tyres. It has also been used to coat or encapsulate electronic assemblies, offering extremely high electrical resistivity. It exhibits a recovery of 80% after stress is applied, a value only exceeded by elastin and resilin.
The major use of polybutadiene is in tyres with over 70% of the polymer produced going into treads and sidewalls. Cured BR imparts excellent abrasion resistance (good tread wear), and low rolling resistance (good fuel economy). Polybutadiene is usually blended with other elastomers like natural rubber or styrene-butadiene rubber for tread compounds. Other applications include polystyrene for injection molding applications and golf balls.
Butyl
Because of butyl polymers’ unique characteristics, barrier properties - high damping, resistance to ozone, heat and chemical, and very low permeability to air, gases and moisture, butyl is ideal for many tyres and automotive applications, healthcare and medical equipments, industrial and construction usage and adhesive and even chewing gum! Butyl rubber is, in fact, the only rubber that is impermeable to air.
In the tyres and automotive industries, butyl polymers can be used for innerliner, non staining black sidewall, white sidewall, treading compound, heat resistant hose and dynamic parts including the body mounts. In medical industry, it can be found in protective clothing and closures for bottles.
