PSU UDEL P-1700
| Notes: | Udel® P-1700 polysulfone (PSU) is a tough, rigid, high-strength thermoplastics suitable for continuous use up to 300°F (149°C). It is resistant to oxidation and hydrolysis and withstand prolonged exposure to high temperatures and repeated sterilization. Udel® P-1700 polysulfone is highly resistant to mineral acids, alkali and salt solutions. Resistance to detergents and hydrocarbon oils is good, but the resin may be attacked by polar solvents such as ketones, chlorinated hydrocarbons and aromatic hydrocarbons. These resins are also highly resistant to degradation by gamma or electron beam radiation. Electrical properties of Udel® P-1700 polysulfones are stable over a wide temperature range and after immersion in water or exposure to high humidity. The resins comply with FDA 21 CFR 177.1655 and may be used in articles intended for repeated use in contact with foods. Additionally, they are approved by the NSF, by the Department of Agriculture for contact with meat and poultry and by the 3-A Sanitary Standards of the Dairy Association.

物料性能/用途
1耐无机酸碱盐的腐蚀，但不耐芳香烃和卤化烃。聚芳砜硬度高，耐辐射，耐热和耐寒性好 并具有自息性，可在-100-175度下长期使用。
2、通过玻璃纤维增强改性可以使材料的耐磨性大幅度提高。
3、可将聚砜与ABS、聚酰亚氨、聚醚醚酮和氟塑料等制成聚砜的改性产品，主要是提高其冲击强度和伸长率、耐溶剂性、耐环境性能、加工性能和可电镀性。如PSF/PBT,PSF/ABS,PSF+矿物粉。 1、适于制作耐热件、绝缘件、减磨耐磨件、仪器仪表零件及医疗器械零件，聚芳砜适于制作低温工作零件。
2、聚砜在电子电器工业常用于制造集成线路板、线圈管架、接触器、套架、电容薄膜、高性能碱电池外壳。
3、聚砜在家用电器方面用于微波烤炉设备、咖啡加热器、湿润器、吹风机、布蒸干机、饮料和食品分配器等。也可代替有色金属用于钟表、复印机、照相机等的精密结构件。
4、聚砜已通过美国医药、食品领域的有关规范，可代替不锈钢制品。由于聚砜耐蒸气、耐水解、无毒、耐高温蒸气消毒、高透明、尺寸稳定性好等特点，可用作手术工具盘、喷雾器、流体控制器、心脏阀、起博器、防毒面具、牙托等。
成型性能 1.无定形料,吸湿大，吸水率0.2%-0.4%，使用前须充分干燥，并防止再吸湿。保证含水量在0.1%以下。
2.成型性能与PC相似，热稳定性差，360度时开始出现分解。
3.流动性差，冷却快，宜用高温高压成型。模具应有足够的强度和刚度，设冷料井，流道应短，浇口尺寸取塑件壁厚的1/2-1/3
4.为减小注塑制品产生内应力，模具温度应控制在100-140度。成型后可采取退火处理甘油浴退火处理，160度，1-5分钟；或采取空气浴160度，1-4小时。退火时间取决于制品的大小和壁厚。
5.聚砜在熔融状态下接近于牛顿体，类似于聚碳酸脂，起流动性对温度比较敏感，在310度-420度内，温度每升高30度，流动性就增加1倍。故成型时主要通过提高温度来改善加工流动性。
