PET回收料造粒机PET是乳白色或浅***、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、***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***快的领域。PETisamilkywhiteorlightyellow,highlycrystallinepolymerwithaglossyrelativelywidetemperaturerangewithexcellentphysicalandmechanicalproperties,long-termuseofupto120℃temperature,excellentelectricalinsulation,evenunderthehightemperatureandhighfrequency,itselectricperformanceisstillgood,creepresistance,fatigueresistance,frictionalresistance,dimensionalstabilityaregood,butthecoronaresistanceisTisdividedintofiber-gradepolyesterchipandnon-fibergradepolyesterisusedtomanufacturepolyesterstaplefiberandpolyesterfilamentyarn,whichistherawmaterialforprocessingfiberandrelatedproductsofpolyesterfiberenterprises.Polyesteristhelargestproductioninchemicalfiber.(2)thefiberpolyesterfilmandbottle,andotherpurposes,arewidelyusedinpackagingindustry,electronicappliances,medicalandhealthcare,c***truction,automotiveandotherfields,includingpackagingisoneofthelargestnonpolyesterfiberapplicationmarket,isalsothefastestgrowthinPET.)
