ABS塑料:丙烯腈-丁二烯-苯乙烯共聚物ABS樹脂是僅次于聚氨酯和聚丙烯的第三大汽車樹脂。ABS塑料比重:1.05g/cm3,成型收縮率:0.4-0.7%,成型溫度:200-240°C,干燥條件:80-90°C持續2小時3.優點:ABS具有良好的剛性,良好的沖擊強度,耐熱性,耐低溫性,耐化學性,易加工,良好的尺寸穩定性和表面光澤度,易于上漆和著色。4。缺點:由于這類產品是真空吹塑的,因此產品制造模具是單面模具,厚度薄,強度差,熱變形溫度低,可燃性和耐候性差,因此這種材料不能用作保險杠。只能制造唇形支架。PU塑料:聚氨酯甲酸酯PU塑料是目前在汽車中使用最廣泛的材料。國外著名汽車品牌,例如寶馬,本田,豐田等,平均每輛汽車需要使用約10KG
PU材料。它分為兩種類型:軟PU和硬PU。回收環保材料以進行再利用。2.優點:吸震性好,耐熱性,耐低溫性,耐化學性,韌性好,重量輕,生產速度快,產品達標,耐碰撞性好(可承受每小時20公里的汽車碰撞力),恢復性好,可以承受360°扭轉,經久耐用,并且易于安裝。3。缺點:模具價格昂貴, 。以上文獻若需轉載請備注出處:pbt塑料 //shanglikaiguan.cn/
