PET 是乳白色或浅黄色、高度结晶的聚合物，表面平滑有光泽。在较宽的温度范围内具有优良的物理机械性能，长期使用温度可达120℃，电绝缘性优良，甚至在高温高频下，其电性能仍较好，抗蠕变性，耐疲劳性，耐摩擦性、尺寸稳定性都很好，但耐电晕性较差。PET分为纤维级聚酯切片和非纤维级聚酯切片。①纤维级聚酯用于制造涤纶短纤维和涤纶长丝，是供给涤纶纤维企业加工纤维及相关产品的原料。涤纶作为化纤中产量高的品种。②非纤维级聚酯还有瓶类、薄膜等用途，广泛应用于包装业、电子电器、医疗卫生、建筑、汽车等领域，其中包装是聚酯的非纤应用市场，同时也是PET增长最快的领域。

PET is a milky white or light yellow, highly crystalline polymer with a glossy finish.In relatively wide temperature range with excellent physical and mechanical properties, long-term use of up to 120 ℃ temperature, excellent electrical insulation, even under the high temperature and high frequency, its electric performance is still good, creep resistance, fatigue resistance, frictional resistance, dimensional stability are good, but the corona resistance is poor.PET is divided into fiber - grade polyester chip and non - fiber grade polyester chip.It is used to manufacture polyester staple fiber and polyester filament yarn, which is the raw material for processing fiber and related products of polyester fiber enterprises.Polyester is the largest production in chemical fiber.(2) the fiber polyester film and bottle, and other purposes, are widely used in packaging industry, electronic appliances, medical and health care, construction, automotive and other fields, including packaging is one of the largest non polyester fiber application market, is also the fastest growth in PET.
