补充资料：热塑料性塑料
热塑料性塑料
热塑料性塑料是指在特定温度范围内能反复加热软化和冷却硬化的塑料，如聚乙烯、聚四氟乙烯等。热塑料性塑料又分烃类、含极性基因的乙烯基类、工程类、纤维素类等多种类型。
①烃类塑料。属非极性塑料，具有结晶性和非结晶性之分，结晶性烃类塑料包括聚乙烯、聚丙烯等，非结晶性烃类塑料包括聚苯乙等。
②含极性基因的乙烯基类塑料。除氟塑料外，大多数是非结晶型的透明体，包括聚氯乙烯、聚四氟乙烯、聚醋酸乙烯酯等。乙烯基类单体大多数可以采用游离基型催化剂进行聚合。
③热塑性工程塑料。主要包括聚甲醛、聚酰胺、聚碳酸酯、abs、聚苯醚、聚对苯二甲酸乙二酯、聚砜、聚醚砜、聚酰亚胺、聚苯硫醚等。聚四氟乙烯。改性聚丙烯等也包括在这个范围内。
④热塑性纤维素类塑料。主要包括醋酸纤维素、醋酸丁酸纤维素、塞璐珞、玻璃纸等。
