Polybutadiene Rubber, PBR

Polybutadiene was one of the first elastomers or tires that was invented, 70% of poly-butadiene is used to make rubber and tire, and 25% to 30% of it is added as an additive to other tires.Polybutadiene Rubber, PBR is the second largest volume synthetic rubber produced, next to styrene-butadiene rubber (SBR).

Polybutadiene may be prepared in several ways to yield different products. The method of polymerization can have a marked effect on polymer structure, which in turn controls the properties of the polymer and thus its ultimate end use. Polybutadiene Rubber which is a polymerized by butadiene is the most elastic rubber type. Major application for BR include tire treads, tire carcass and sidewalls, under-treads, cycle tires, conveyor belts, sportswear, golf balls, automotive components, conveyor belts and shoe heels and soles. BR is also well suited for the production of flexible rollers and mechanical goods due to its superior elasticity, resilience and abrasion properties.

What is Polybutadiene Rubber, PBR?

Polybutadiene Rubber, PBR  is a polymer formed from the polymerization process of the monomer 1,3 – Butadiene, has a high resistance to wear and is used especially in the manufacture of tires, also it is used as an additive to improve the mechanical strength of plastics such as polystyrene and ABS.

We have high polybutadiene rubber. Polybutadiene rubber is produced by a solution based polymerization and cobalt catalyst. Actually PBR properties, such as abrasion resistance PBR and excellent tear strength PBR, high resilience and very low glass transition temperatures (around -100 ° C), after styrene-butadiene SBR is the most used synthetic elastomer. Butadiene in terms of volume of production is the ninth petrochemical production of the world (after ammonia, ethylene, propylene, methanol, xylene, benzene, butylene and toluene) .And the bulk of it is also used as a monomer for rubber production. In 2015, 11 million and 447 thousand tons of butadiene have been consumed worldwide.

Application for Polybutadiene Rubber, PBR

The high abrasion resistance and impact resistance of the rubber butadiene has led to the use in the manufacture of tires for riding cars, trucks and racing cars. Also, the tire tread is also made of Poly Bottoming copolymers. Be used in the manufacture of shoes, belts and conveyors, rubber sponges, hoses and washers, butadiene roller balls.

The most important applications of Polybutadiene Rubber, PBR are tire and rubber parts.




Properties of Polybutadiene Rubber, PBR

 Wear resistance   

High Elasticity

High abrasion resistance in severe conditions

Low temperature properties

Low hysteresis

 Low rolling resistance

Good flexibility at ambient temperatures

Difference between PBR and SBR 

Polybutadiene rubber, PBR the second largest volume elastomer, accounts for approximately 25 percent of the total global consumption of synthetic rubbers. Due to its very low vinyl content it has a very low glass transition temperature (-90 °C), very high resilience and is probably the most elastic rubber. Polybutadiene Rubber, PBR also has good abrasion and tear resistance as well as low heat buildup, which is important for tire applications. Compared to SBR, it has a lower glass transition temperature, which gives it a lower rolling resistance. However, it has lower friction on wet surfaces than SBRs. For this reason, it is usually blended with SBRs and natural rubbers to achieve the best tire

The Polybutadiene rubber, PBR is and will continue to be a high volume rubber for use in toughened plastics, tires, and golf balls due to its low cost, availability and unique properties.

Precautions for safe handling for work with Polybutadiene Rubber, PBR

Provided good ventilation and/or local exhaust systems are used in this location.

Avoid prolonged or repeated contact polybutadiene rubber, PBR with skin. Use good personal hygiene.

Do not consume or store food in the work area.

Wash hands before smoking or eating.

Take precautionary measures against static discharges.

Electrically bond and ground all containers and equipment before transfer or use of material the polybutadiene rubber, PBR.

Disadvantages PBR:

Low resistance to oils, petrol and hydrocarbon solvents (aliphatic and aromatic), low resistance to atmospheric and ozone, low resistance to gases, low thermal resistance, low flame and flame resistance.

Advantages PBR:

Water resistance, resistance to sunlight, relatively suitable price. Butadiene is polymerized by three methods, in which case three isomers of Cis, Trans, and Vinyl are obtained. The properties of polybutadiene will change depending on the percentage of these three isomers.

PBR has a high percentage of cysts, is called High Cis Polybutadiene and is highly reactive, while PBR has a high percentage of Trans, is called High Trans Polybutadiene, and is a crystalline plastic without any useful use

Properties PBR:

Polybutadiene rubber, PBR is extremely durable against wear and tear and cracking. Resistance to abrasion, low heat generation and non-hot under dynamic and constant stresses, non-sticking, low temperature resilience, good resistance to acid, opening, alcohol and oxygen.

Solvent PBR: Toluene, THF-Tetrahydrofuran, ODCB, TCB-Trichlorobenzene,

Melting Temperature (Tm) PBR: 2 to 12° C
