热塑性弹性体(TPE)是一种具有硫化胶性能与热塑性塑料可再回收加工性能的材料。这些材料的使用性能与普通热固性材料(如天然橡胶)相似。然而它们是通过注塑、挤出和吹塑工艺制成产品的,通常与加工聚丙烯和聚乙烯所用的生产线一样。与热固性橡胶相比,TPE拥有许多优点:1)很少或不用配合;2)工艺简单;3)回收便利;4)密度较低;5)设计灵活性较大。 Thermoplastic elastomers (TPE) are materials that have the properties of vulcanizates and the recyclability of thermoplastics. The performance of these materials and general thermosetting materials (such as natural rubber) similar. However, they are made through injection molding, extrusion and blow molding processes, often the same lines used to process polypropylene and polyethylene. Compared with thermoset rubber, TPE has many advantages: 1) little or no cooperation; 2) simple process; 3) recycling convenience; 4) low density; 5) greater design flexibility.
