Features of Styrene Butadiene Rubber Powder:

Styrene Butadiene Rubber (SBR) powder is a synthetic rubber material with the following features:

1. Elasticity: SBR powder has high elasticity, making it an ideal material for rubber products that require flexibility and resilience.

2. Abrasion Resistance: SBR powder exhibits excellent resistance to wear and tear, making it suitable for use in applications where the rubber product is exposed to harsh conditions and heavy use.

3. Tear Strength: SBR powder has good tear strength, which helps prevent the material from ripping or tearing under stress.

4. Cost-Effective: SBR powder is a cost-effective alternative to natural rubber, as it can be produced at a lower cost and can be made from recycled rubber.

5. Eco-Friendly: SBR powder is an environmentally friendly material as it can be made from recycled rubber and does not require the use of natural resources.
