Black PAI board "Imported PAI polyamide-imide board round rod tawny board

(Polysulfone)
>Product name (Polysulfone)
It is a slightly amber amorphous transparent or translucent polymer with good radiation stability, low ionic impurities and good Excellent chemical resistance and hydrolysis resistance.
>Main Features
The maximum allowable operating temperature in the air is very high (can continue to work at 10 degrees Celsius). High thermal stability, hydrolysis resistance, small molding shrinkage, non-toxic, radiation-resistant, flame-resistant and extinguishing properties. Excellent electrical properties over a wide temperature and frequency range. Good chemical stability, good mechanical strength and high rigidity over a wide temperature range. Excellent hydrolysis resistance, physical inertness, very good dimensional stability, translucent, opaque, light-resistant, UV-resistant, high-energy radiation resistant, good electrical insulation properties.
>Material properties/purposes
Polysulfone is an amber transparent solid material with high hardness and impact strength, non-toxic, heat and cold resistance, good aging resistance and can be used for a long time under high temperatures. Resistant to corrosion by inorganic acids, alkalis and salts but not resistant to aromatic hydrocarbons and halogenated hydrocarbons. Polyarylsulfone has high hardness, good radiation resistance, heat resistance and cold resistance, and has self-interesting properties. It can be used at high temperatures for a long time. The wear resistance of the material can be greatly improved through glass fiber reinforcement and modification. Modified products of polysulfone made from polyimide, polyetheretherketone and fluoroplastics are mainly to improve its impact strength, elongation, solvent resistance, environmental resistance, processing performance and electroplatability. Such as mineral powder.
Suitable for making heat-resistant parts, insulation parts, wear-reducing wear-resistant parts, instrument parts and medical device parts. Polyarylsulfone is suitable for making low-temperature working parts
Polysulfone is often used in the electronic and electrical industry to make integrated circuit board coils. Pipe racks, contactors, sleeves, capacitor films, high-performance alkaline batteries, polysulfone, etc. In household appliances, they are used in microwave ovens, coffee heaters, humidifiers, hair dryers, cloth evaporators, beverage and food dispensers, etc. It can also be used in precision structures such as watches, copiers, cameras, etc. instead of non-ferrous metals. Polysulfone has passed the relevant specifications in the medical and food fields of the United States and can replace stainless steel products. Because polysulfone is steam-resistant, hydrolysis-resistant, non-toxic, resistant to high-temperature steam sterilization, highly transparent, and has good dimensional stability, it can be used as surgical tool trays, sprayers, fluid controllers, heart valves, pacemakers, gas masks, dental trays
Molding and setting materials are hygroscopic and have large water absorption. It must be fully dried before use and prevented from absorbing moisture again. Ensure that the water content begins to separate when the molding performance and similar thermal stability are different. The fluidity is poor and the cooling is fast. It is suitable to use high temperature and high pressure molding. The mold should have sufficient strength and rigidity, the cold slug well and the runner should be short, and the gate size should be short and the wall of the plastic part should be small. In order to reduce the internal stress produced by the injection molded product, the mold temperature should be controlled to a certain degree. After molding, annealing treatment can be performed in a glycerin bath for 1 minute or in an air bath for 1 hour. The annealing time depends on the size and wall of the product. In the molten state, sulfone is close to a Newtonian body, similar to polycarbonate, and its fluidity is sensitive to temperature. The fluidity increases twice as the temperature increases within a certain degree. Therefore, the processing fluidity is mainly improved by increasing the temperature during molding.
>Application fields
Electronic insulation components are widely used in food processing equipment, such as mechanical pumps, valves, filters, heat exchangers, etc. They are also often used in medical devices related to repeated cleaning and disinfection.
