热塑性聚酯弹性体TPEE-25D技术说明
 Technical description of thermoplastic polyester elastomer TPEE-25D


TPEE-25D是一款邵氏硬度25D,颜色稳定的TPEE热塑性聚酯弹性体。它具有良好的低温耐冲击性,且在*高使用温度110℃下仍保持良好的机械性能。可满足食品接触FDA认证级别。可用传统的热塑性模制技术注塑成型或挤出成型。广泛应用于软管和管件,电线电缆,薄膜片材,输送带,塑料橡胶改性等产品。
TPEE-25D is a stable color TPEE thermoplastic polyester elastomer with shore hardness of 25D. It has good low-temperature impact resistance, and still maintains good mechanical properties at the maximum service temperature of 110℃. It can meet the FDA certification level of food contact. Traditional thermoplastic molding technology can be used for injection molding or extrusion molding. It is widely used in hoses and pipe fittings, wires and cables, film sheets, conveyor belts, plastic rubber modification and other products.
