Polybutadiene, trans
polymerTrans-polybutadiene is a synthetic rubber polymer characterized by the geometric arrangement of its double bonds in the trans (E) configuration along the carbon backbone, resulting in a more linear and crystalline structure compared to cis isomers. It is used primarily in tire manufacturing, adhesives, and elastomeric compounds where dimensional stability, low-temperature flexibility, and resilience are valued; it is notably preferred over cis-polybutadiene in applications requiring higher modulus and better abrasion resistance. The trans configuration makes it particularly suitable for industrial elastomer blends and specialty rubber products where controlled chain geometry enhances material 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.
