PSU Polysulfone CNC Machining

Polysulfone is an amber transparent solid material with high hardness and impact strength, non-toxicity, good heat and cold resistance and aging resistance, and can be used for a long time under -100 to 175 degrees Celsius

 

 

Specific gravity:1.25-1.35g/cm3 Forming shrinkage:0.5-0.7% Forming temperature:290-350°C Drying condition:130-150°C 4 hours

 

 

1. Resistant to corrosion of inorganic acids and alkalis, but not resistant to aromatic hydrocarbons and halogenated hydrocarbons. Polyarylsulfone high hardness, radiation resistance, heat and cold resistance and has a self-extinguishing, can be used for a long time at -100-175 degrees.

 

2. Through the glass fiber reinforced modification can make the wear resistance of the material is greatly improved.

 

3. Polysulfone can be made into modified polysulfone products with ABS, polyimide, polyether ether ketone and fluoroplastics, etc., mainly to improve its impact strength and elongation, solvent resistance, environmental performance, processing performance and electroplatability. Such as PSF/PBT, PSF/ABS, PSF + mineral powder. 

 

1, Suitable for the production of heat-resistant parts, insulation parts, wear parts, instrumentation parts and medical equipment parts, polysulfone is suitable for the production of low-temperature parts.

 

2, Polysulfone in the electronic and electrical industry is commonly used in the manufacture of integrated circuit boards, coil tube frame, contactor, set frame, capacitor film, high-performance alkaline battery shell.

 

3, Polysulfone in household appliances for microwave oven equipment, coffee heaters, wetter, hair dryer, cloth steamer, beverage and food distributor. Can also be used instead of non-ferrous metals for clocks and watches, copiers, cameras and other precision structural components.

 

4, Polysulfone has passed the U.S. pharmaceutical, food field of the relevant norms, can replace stainless steel products. Due to the polysulfone steam resistance, hydrolysis resistance, non-toxic, high temperature steam sterilization, high transparency, good dimensional stability, etc., can be used as surgical tool trays, nebulizers, fluid controllers, cardiac valves, pacemakers, gas masks, dental brackets and so on.

 

 

1. Amorphous material, moisture absorption, water absorption rate of 0.2%-0.4%, must be sufficiently dry before use, and to prevent re-absorption of moisture. Ensure that the water content is below 0.1%.

 

2. Molding performance is similar to PC, poor thermal stability, decomposition begins at 360 degrees.

 

3. Poor fluidity, fast cooling, suitable for high temperature and high pressure molding. The mold should have enough strength and rigidity, set up a cold material well, the runner should be short, the gate size to take the wall thickness of the molded part of 1/2-1/3

 

4. In order to reduce the internal stress of injection molded products, the mold temperature should be controlled at 100-140 degrees. After molding can take annealing treatment glycerin bath annealing treatment, 160 degrees, 1-5 minutes; or take the air bath 160 degrees, 1-4 hours. Annealing time depends on the size of the product and wall thickness.

 

5. Polysulfone in the molten state close to the Newtonian body, similar to polycarbonate, the mobility of the temperature sensitive, in the 310 degrees -420 degrees within the temperature increases every 30 degrees, the mobility increased by a factor of one. Therefore, the molding is mainly by increasing the temperature to improve the processing fluidity.

 

 

 

 

PSU has a wide range of applications, in the field of electrical and electronic, PSU can be used to make a variety of contactors, connectors, transformer insulation, SCR caps, insulating bushings, coil skeletons, terminal blocks and collector rings and other electrical parts, printed circuit boards, bushings, hoods, TV system parts, capacitor film, brush holders [1], alkaline battery boxes, etc.; in the field of automotive, aviation, PSU can be used to make Shield components, electric gear, battery cover, detonator, electronic ignition device components, lamps and lanterns parts, aircraft internal accessories and aircraft external parts, spacecraft external shields and so on. PSU can also be used to produce illuminator gear, electric drives, sensors, etc., the world market used to make cabin parts of polysulfone polymer demand continues to grow, mainly due to the combustion of such polymers release less heat, produce less smoke, less diffusion of toxic gases, in full compliance with the safety regulations of the use of the requirements; in the kitchenware market, PSU can be used in place of glass and stainless steel products for the Manufacture of steam trays, coffee containers, microwave cookers, milk and agricultural products containers, egg stoves and milking parts, beverage and food dispensers, etc. PSU is a non-toxic products can be made into repeated contact with food utensils. PSU as a transparent new material, heat and water resistance, hydrolytic stability is better than any other kind of thermoplastic, so it can be used to make coffee pots and so on. Connection tube made of PSU, used for glass fiber or glass fiber reinforced polyester masonry, tube outer layer of high strength, tube inner layer of chemical resistance, lighter than steel, and transparent, easy to clinical control, commonly used in the food industry and the production of lamps and lamps of the lamps; in the health and medical equipment, PSU can be used for the production of surgical trays, nebulizers, humidifiers, contact lens fixtures, flow rate controllers, instrument covers, dental instruments, liquids, and medical devices. PSU can be used to make a variety of medical products than the cost of glass products, and not easy to rupture, so it can be used for instrument housings, dental instruments, heart valve box, blade cleaning system, soft contact lens molding box, micro-filter, dialysis membrane, etc. PSU can also be used for dental veneers, the adhesive strength of which is twice as high as that of acrylic acid; in daily necessities, PSU can be used to make humidifiers, hair dryers, hair dryers and other products. In daily necessities, PSU can be used to make humidifier, hair dryer, clothing steam, camera box, projector components and other heat-resistant, hydrolysis-resistant products. By 0.4-1.6MGy radiation and good drying over the PSU granules, at 310 ℃ and mold temperature 170 ℃ is easy to injection molding, suitable for laminating materials, adhesives, all the polysulfone with silane, such as PSU-SR, PKXR, etc. can be used as an adhesive for the sizing of glass fibers and graphite fibers to make composite materials, graphite fabrics reinforced with silanes with the PSU, can be made to elevate the rudder and other aircraft parts. PSU in addition to solid lubricant PTFE, can increase wear resistance and physical and mechanical properties, but also used in the preparation of wear-resistant coatings; in addition, PSU can also be manufactured in a variety of chemical processing equipment (such as pump covers, tower outer protective layer, etc.), food processing equipment, pollution control equipment, dairy processing equipment and engineering, construction, chemical piping and so on.
