| NYTEF塑料公司生产的UNIPET® PET是一种半结晶聚酯对苯二甲酸酯（PET）聚合物，具有优异的强度、硬度和机械加工性。此外，这种材料提供尺寸稳定性和耐磨性，达到或超过尼龙或乙缩醛。由于其优异的耐化学性和食品接触认证，UNIPET® PET库存形状是食品加工应用中部件的首选材料，如活塞、阀门、进料螺钉以及食品成型和挤压模具。此外，unipet提供的低吸湿性和低热膨胀率使其非常适合需要精密加工部件的高要求应用。UNIPET® PET机器容易，由NYTEF塑料公司提供各种各样的挤压棒和大规格板尺寸。UNIPET® PET属性230°F连续使用温度高强度和硬度优异耐磨耐氯和腐蚀性/酸性清洁剂的化学性能比缩醛或尼龙提高了抗紫外线性能极低吸湿性极易加工和制造FDA、USDA和3-A乳品合规性极高“性价比”RaTIO典型工业食品和乳制品加工材料搬运设备流体搬运电子产品制造汽车应用活塞阀组食品产品成型模具正时螺钉刮刀刀片 UNIPET PET from Nytef Plastics is a semicrystalline polyester terephthalate (PET) polymer that exhibits excellent strength, rigidity, and machinability. Additionally, this material offers dimensional stability and wear resistance that meets or exceeds that of nylon or acetal. Due to it's superior chemical resistance and food contact approvals, UNIPET PET stock shapes are the preferred material for components in food processing applications such as pistons, valves, feed screws, and food product forming and extrusion dies. Additionally, the low moisture absorption and low rate of thermal expansion offered by UNIPET makes it ideal for demanding applications that require close tolerance, precisely machined component parts. UNIPET PET machines easily and is offered by Nytef Plastics in a complete range of extruded rod and heavy gauge plate sizes. UNIPET PET ATTRIBUTES 230°F continuous use temperature High strength and stiffness Superior wear resistance Chemically resistant to chlorine and caustic/acidic cleaning agents Improved UV resistance compared to acetal or nylon Very low moisture absorption Easily machined and fabricated FDA, USDA, and 3-A Dairy Compliant Very high "Value to Cost" ratio TYPICAL INDUSTRIES Food and dairy processing Material handling equipment Fluid handling Electronics manufacturing Automotive APPLICATIONS Pistons Valves Manifolds Food product forming dies Timing screws Scraper blades |
