Polybutadiene,_cis

polymer

Cis-polybutadiene is a synthetic rubber polymer characterized by a high proportion of cis-1,4-linkages in its backbone chain, giving it excellent elasticity and resilience compared to trans-isomers. It is widely used in tire manufacturing (particularly truck and high-performance tires), adhesives, and impact-modified plastics where superior flexibility and low-temperature performance are required. Engineers select cis-polybutadiene over alternatives like natural rubber or butadiene-styrene copolymers when high rebound characteristics, fatigue resistance, and processability in industrial synthesis are critical to performance.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
