Poly(1-butene)
polymerPoly(1-butene) is a semi-crystalline thermoplastic polymer produced by the polymerization of 1-butene monomers, belonging to the polyolefin family alongside polyethylene and polypropylene. It is primarily used in packaging films, flexible tubing, and molded components where moderate stiffness combined with good flexibility and chemical resistance are required. Poly(1-butene) offers advantages over standard polyethylene in applications requiring improved puncture resistance and environmental stress-crack resistance, making it particularly valuable in flexible film applications and pressure piping where durability under stress is critical.

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.
