butadiene rubber compound (BR)

butadiene rubber compound (BR)

Butadiene rubber (BR,Polybutadiene Rubber) generally refers to high cis 1,4-polybutadiene rubber, which is the most prominent variety of elasticity, abrasion resistance and cold resistance in general synthetic rubber. It is often used in combination with natural rubber and styrene butadiene rubber and rarely used alone.
Product Features

Features:Elasticity, cold resistance, wear resistance, low heat generation

Disadvantages:Poor tensile strength, tear resistance, poor processability

Application:Tire sidewalls, treads, highly elastic products

Product Description

Excellent elasticity

General rubber has the highest rebound and low dynamic heat generation, which is suitable for high-speed and repeated stress conditions.

Wear resistance top

Wear resistance far more than natural rubber, styrene-butadiene rubber, is the core material of tire tread.

Excellent cold resistance

The glass transition temperature is low, can remain flexible at -70 ℃, and the cold resistance is better than most general-purpose adhesives.

Flexure resistance, dynamic fatigue resistance

Repeated bending is not easy to crack, suitable for tires, shock absorption, transmission belt.
