聚砜PSU颗粒

产品详细信息

比重：1.25-1.35g/cm³

成型收缩率：0.5-0.7%

成型温度：290-350℃

干燥条件：130-150℃，小时

材料性能

1，聚砜是琥珀色透明固体材料，硬度和冲击强度高，无毒，抗热、耐寒和耐老化性能好，可在-100-175度下长期使用。耐无机酸和碱性盐腐蚀，但不耐芳烃和卤化

玻璃纤维增强改性可显著提高材料的耐磨性

3，聚砜可以用ABS、聚酰亚胺、聚醚醚酮和氟塑料进行改性，制成聚砜改性产品，主要是提高其冲击强度和伸长率、耐溶剂性、耐环境性、加工性能和电镀性能。例如，PSU/PBT、PSU/ABS、PSU+矿粉

成型性能：

1。吸水率高的无定形材料，吸水率在0.2%-0.4%之间，在使用前必须完全干燥，防止水分再次吸收。确保含水量低于0.1%

2、成型性能与PC相似，热稳定性差，360度开始分解

3，流动性差，冷却快，适合高温高压成型。模具应具有足够的强度和刚度，具有冷槽、短流道和浇口尺寸为塑料件壁厚的1/2-1/3

4，为了降低注塑制品的内应力，模具温度应控制在100-140度。成型后，可在160度的甘油浴中进行1-5分钟的退火，或在160度的空气浴中进行1-4小时的退火。退火时间取决于产品的尺寸和壁厚

5，聚砜在熔融状态下接近牛顿体，类似于聚碳酸酯，从流动性来看对温度更敏感，在310度-420度之间，温度每30度升高一次，流动性就会增加1倍。因此，提高成型温度是提高加工流动性的主要途径

应用程序

1，适用于制造耐热零件、绝缘零件、耐磨零件、仪器零件和医疗设备零件，也适用于制造低温工作零件

聚砜通常用于制造集成电路板、线圈架、接触器、套管、电容器薄膜和电气电子行业的高性能碱性电池外壳

聚砜用于微波炉设备、咖啡加热器、湿器、吹风机、蒸布机、饮料和食品分配器等家用电器中。。也可代替有色金属用于钟表、复印机、相机等精密结构件

4，聚砜已通过美国医药和食品领域的相关规范，可替代不锈钢产品，用作手术工具托盘、喷雾器、液体控制器、心脏瓣膜、起搏器、防毒面具、牙科支架等。

Polysulfone PSU Granules

Product Details

Specific gravity: 1.25-1.35g/cm³;

Molding shrinkage: 0.5-0.7%

Molding temperature: 290-350°C

Drying conditions: 130-150°C, hours

Material performance.

1, polysulfone is amber transparent solid material, high hardness and impact strength, non-toxic, good heat and cold resistance and aging resistance, can be used under -100 – 175 degrees for a long time. It is resistant to the corrosion of inorganic acids and alkaline salts, but not to aromatic hydrocarbons and halogenation;

2、The abrasion resistance of the material can be greatly improved by glass fiber reinforced modification;

3, Polysulfone can be modified with ABS, polyimide, polyether ether ketone and fluoroplastics to make modified products of polysulfone, mainly to improve its impact strength and elongation, solvent resistance, environmental resistance, processing performance and plating. For example, PSU/PBT, PSU/ABS, PSU + mineral powder.

Molding properties:

1. Amorphous material with high moisture absorption, 0.2%-0.4% water absorption, must be fully dried before use and prevent re-absorption of moisture. Ensure that the water content is below 0.1%;

2、Moulding performance is similar to PC, poor thermal stability, decomposition starts at 360 degrees;

3, poor liquidity, fast cooling, suitable for high temperature and high pressure molding. The mould should have sufficient strength and rigidity, with cold wells, short runners and a sprue size of 1/2-1/3 of the wall thickness of the plastic part;

4, in order to reduce the internal stress of the injection moulded products, the mould temperature should be controlled at 100-140 degrees. After moulding, annealing can be carried out in a glycerine bath at 160 degrees for 1-5 minutes or in an air bath at 160 degrees for 1-4 hours. Annealing time depends on the size and wall thickness of the product;

5, polysulfone in the molten state is close to the Newtonian body, similar to polycarbonate, from the liquidity is more sensitive to the temperature, in 310 degrees – 420 degrees, the temperature increases every 30 degrees, the liquidity will increase 1 times. Therefore, the main way to improve the processing fluidity is to increase the temperature when molding.

Application.

1, suitable for making heat-resistant parts, insulating parts, wear-resistant parts, instrument parts and medical equipment parts, also suitable for making low-temperature working parts;

2、Polysulfone is commonly used in the manufacture of integrated circuit boards, coil racks, contactors, sleeves, capacitor films and high-performance alkali battery shells in the electrical and electronics industry;

3, Polysulfone is used in household appliances for microwave oven equipment, coffee heaters, wet ware, hair dryers, cloth steamers, beverage and food dispensers, etc.. It can also be used instead of non-ferrous metals for precision structural parts of clocks and watches, photocopiers, cameras, etc;

4, Polysulfone has passed the relevant specifications in the field of medicine and food in the United States, and can replace stainless steel products, used as surgical tool trays, sprayers, fluid controllers, heart valves, pacemakers, gas masks, dental brackets, etc.
