亚克力和热缩片的区别？

亚克力又叫PMMA或有机玻璃，源自英文acrylic(丙烯酸塑料)，化学名称为聚甲基丙烯酸甲酯。是一种开发较早的重要可塑性高分子材料，具有较好的透明性、化学稳定性和耐候性、易染色、易加工、外观优美，在各行各业中有着广泛应用。
热缩材料又称高分子形状记忆材料，是高分子材料与辐射加工技术交叉结合的一种智能型材料。普通高分子材料如聚乙烯、聚氯乙烯等通常是线形结构，经过电子加速器等放射源的辐射作用变成网状结构后，这些材料就会具备独特的"记忆效应"，扩张、冷却定型的材料在受热后可以重新收缩恢复原来的形状。热缩材料的记忆性能可用于制作热收缩管材、膜材和异形材，主要特性是加热收缩包覆在物体外表面，能够起到绝缘、防潮、密封、保护和接续等作用，收缩材料的径向收缩率可达50%-80%。
