UNILATE® PBT是一种半结晶聚对苯二甲酸丁二醇酯(PBT)材料,具有优异的刚性、韧性和可加工性。此外,UNILATE® PBT提供尺寸稳定性和耐磨性,达到或超过尼龙和乙缩醛。由于其优异的耐化学性和食品接触认证,Unilate是干湿食品加工应用中的首选材料,如活塞、阀门、进料螺钉和成型/挤压模具。对于涉及高速磨损的应用,Unilate有内部润滑等级Unilate LF,与非润滑等级相比摩擦系数要低得多。产品属性225°F连续使用温度高强度和刚度优异韧性优异耐磨耐化学性耐氯和腐蚀性/酸性清洗剂比缩醛或尼龙耐紫外线性能好吸水性极低易加工和制造FDA、USDA、NSF和3-A合规性极高“值成本比率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阀组食品产品成型模具正时螺钉刮刀刀片磨损带泵部件齿轮衬套和轴承 UNILATE PBT is a semi-crystalline polybutylene terephthalate (PBT) material that exhibits excellent rigidity, toughness, and machinability. Additionally, UNILATE PBT offers dimensional stability and wear resistance that meets or exceeds that of nylon and acetal. Due to its superior chemical resistance and food contact approvals, UNILATE is the preferred material for components in wet and dry food processing applications such as pistons, valves, feed screws, and forming/extrusion dies. For applications involving high speed wear, UNILATE is available in an internally lubricated grade, UNILATE Lf, that provides a much lower coefficient of friction compared to non-lubricated grades. PRODUCT ATTRIBUTES 225°F continuous use temperature High strength and stiffness Excellent toughness Superior wear resistance Chemically resistant to chlorine and caustic/acidic cleaning agents Better UV resistance than acetal or nylon Very low moisture absorption Easily machined and fabricated FDA, USDA, NSF, and 3-A compliant Very high "value to cost" ratio 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 Wear strips Pump components Gears Bushings and bearings |
