Tokyo/Japan — Sunprene is a PVC thermoplastic elastomer that not only possesses PVC’s intrinsic moldability and oil resistance characteristics, but also adds mechanical properties such as rubber elasticity, provided by MCC’s compound technology, and has applications in a broad range of fields such as automotive components and building materials. In general, PVC’s mechanical properties are highly temperature-dependent, and it is very susceptible to changes in the usage environment. In low-temperature environments, it becomes harder, resulting in lower elasticity.

According to the manufacturer, the new MCC-developed series marks a significant improvement in the material’s cold resistance, while maintaining PVC’s intrinsic characteristics, due to its polymer alloy technology. Therefore, changes in its physical properties are minimal even in low-temperature environments, allowing it to maintain high elasticity. The new series has already been adopted by a major Japanese OEM for exterior molding parts that help prevent excessive wind noise while traveling, the company announced.
