Why is polybutadiene used in tires?

Why is polybutadiene used in tires?

Polybutadiene has the advantage compared to SBR in its lower liquid-glass transition temperature, which gives it a high resistance to wear and a low rolling resistance. This gives the tires a long life and low fuel consumption.

What is the common name of polybutadiene?


COMMON NAMES Poly(1,4-butadiene)
STRUCTURE BASED NAME Poly(but-2-ene-1,4-diyl)
CAS # 9903-17-2

What is polybutadiene rubber?

Polybutadiene rubber is a polymer formed from the polymerization of the monomer 1,3-butadiene. Polybutadiene has a high resistance to wear and is used especially in the manufacture of tires, which consumes about 70% of the production.

What are the properties and performance of polybutadiene?

2 The properties and performance of polybutadiene strongly depend on the isomeric structure, degree of branching and crosslinking as well as on the composition (type and amount of additives). Abrasion Resist. Weather Resist. Mineral Oil Resist.

What is the density of butyl rubber?

Density of butyl rubber is around 0.92 gr/cm^3. Tyres made with butadiene rubber. This synthetic elastomer is combined with other rubber to produce automotive tires. It is generally mixed with natural rubbers. In some applications, butadiene rubber is mixed with styrene to obtain styrene-butadiene rubber.

What are the disadvantages of butadiene rubber?

Butadiene rubbers are not resistant to oil, gasoline and hydrocarbon solvents. They also have poor heat resistance and are susceptible to attack by ozone due to the presence of double bonds in the polymer backbone which are prone to thermal-oxidative degradation.
