熱塑性聚酯彈性體TPEE-55D技術(shù)說明
Technical description of thermoplastic polyester elastomer TPEE-55D
TPEE-55D是一款邵氏硬度55D，顏色穩(wěn)定的TPEE熱塑性聚酯彈性體。具有良好的低溫耐沖擊性，且在*高使用溫度120℃下仍保持良好的機(jī)械性能。可滿足食品接觸FDA認(rèn)證級別。可用傳統(tǒng)的熱塑性模制技術(shù)注塑成型或擠出成型。廣泛應(yīng)用于軟管和管件，電線電纜，消音齒輪，輸送帶，塑料橡膠改性等產(chǎn)品。
TPEE-55D is a stable color TPEE thermoplastic polyester elastomer with shore hardness of 55D. It has good low-temperature impact resistance, and still maintains good mechanical properties at the maximum service temperature of 120℃. 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, silencing gears, conveyor belts, plastic rubber modification and other products.
