Polybutadiene [MW ~1,600]

Polybutadiene (PB) is a synthetic rubber polymer composed of butadiene monomers. It has high elasticity, excellent abrasion resistance, and low-temperature flexibility, making it an essential material in the rubber and plastics industries. Depending on its microstructure, polybutadiene can be categorized into high-cis, low-cis, or high-vinyl forms, each with unique properties.
1,2-vinyl content: 80% Applications: Tire Manufacturing: Enhances wear resistance and durability in automotive tires. Adhesives & Sealants: Provides flexibility and impact resistance in industrial adhesives. Polymer Blends: Used as an impact modifier in polystyrene and ABS plastics.
