China and the United States are the leading exporters of Polyisoprene Trans (CAS 104389-32-4), accounting for the majority of global shipments, while Germany, South Korea, and Japan represent the largest importing markets. Polyisoprene Trans prices have remained relatively stable amid consistent bilateral trade flows between these key economies. No significant shift in the top exporting or importing countries has occurred over the past three years, indicating sustained regional supply chain positioning and demand continuity.
Polyisoprene Trans is a white to off-white, non-volatile, thermoplastic solid at room temperature, typically supplied as pellets or powder, with no characteristic odor and a melting point range of approximately 60–70 °C. It is a synthetic elastomeric polymer classified as a trans-1,4-polyisoprene, structurally distinct from natural rubber (cis-1,4-polyisoprene). As a specialty elastomer, it serves primarily as a functional intermediate in the formulation of high-performance rubber compounds requiring enhanced heat resistance, crystallinity control, and dimensional stability. Its principal applications are in medical device components (e.g., surgical gloves, tubing), technical rubber goods, and specialty adhesives—particularly where consistent mechanical properties and low protein content are critical. It is also used in niche polymer blends and modifiers for thermoplastic elastomer systems.
