Polybutadiene Rubber (BR)

Description

1. Product Overview

Polybutadiene Rubber (BR) is a high-performance synthetic elastomer known for its exceptional resilience, low heat build-up, and outstanding abrasion resistance. Primarily used in the tire, automotive, and polymer compounding industries, it enhances product durability and operational efficiency. Its superior elasticity and wear resistance make it a strategic material for high-stress applications, ensuring longer service life and reduced maintenance costs. Globally, BR is a critical component in manufacturing high-quality tires, belts, and molded rubber goods, positioning it as an essential sourcing material for industrial manufacturers.
