聚甲醛是一种高性能的缩醛共聚物,具有优异的机械、电气和磨损性能。即使加工具有复杂几何形状的零件,它的设计也能提供卓越的尺寸稳定性。Pomalux是许多轴承和磨损应用的最佳选择,因为它具有低摩擦系数,在潮湿和干燥环境中都能很好地磨损。由于其固有的尺寸稳定性和良好的磨损性能,广泛应用于装配工装夹具中。当需要低吸湿性和高介电强度时,Pomalux通常用于电气应用。天然(白色)和黑色Pomalux都符合FDA标准,可用于食品加工机械。Westlake Plastics Company根据ASTM D6100制造所有缩醛挤压和压缩成型片材、板材和杆材。本规范涵盖了挤压和压缩成型板材、板材和杆的材料、尺寸、工艺和性能的要求和试验方法。应用范围包括:钻模和夹具泵和阀门零件衬套轴承齿轮耐磨垫电气元件POMALUX的优点:高强度和刚度低摩擦易于加工尺寸稳定性好低吸湿性在潮湿和干燥环境下耐磨损性好耐化学性好电气性能好符合FDA的特性 Pomalux is a high-performance acetal copolymer that has excellent mechanical, electrical, and wear properties. It is engineered to provide outstanding dimensional stability, even when machining parts with complex geometries. Pomalux is an excellent choice for many bearing and wear applications since it has low coefficient of friction and wears well in both wet and dry environments. It is widely used for assembly jigs and fixtures because of its inherent dimensional stability and excellent wear properties. Pomalux is often specified for electrical applications when low moisture absorption and high dielectric strength are required. Both natural (white) and black Pomalux are FDA compliant for use in food processing machinery. Westlake Plastics Company manufactures all Acetal extruded & compression molded sheets, plates and rods in accordance to ASTM D6100. This specification covers requirement and test methods for the material, dimensions, workmanship and the properties of extruded and compression molded sheets, plates and rods. Applications Include: Jigs and fixtures Pump and valve parts Bushings Bearings Gears Wear pads Electrical components Advantages of Pomalux: High strength and stiffness Low friction Easy to machine Good dimensional stability Low moisture absorption Resists abrasive wear in both wet and dry environments Good chemical resistance Excellent electrical properties FDA compliant |
