Polyisoprene is a synthetic rubber polymer that replicates the structure and performance of natural rubber, offering excellent elasticity and resilience across a wide temperature range. It is widely used in tire manufacturing, seals, gaskets, and flexible tubing where high elongation, resilience, and moderate temperature tolerance are required. Engineers select polyisoprene over other elastomers when natural rubber properties are needed with improved consistency, chemical stability, or when synthetic alternatives to latex are preferred for cost or supply-chain reasons.
