PSU - Molding Process
Open Data Verified Data
pre-drying to a moisture content of less than 0. OS% prior to PSF molding. PSF can be injection molding, molding, extrusion, thermoforming, blow molding and other molding processing, high melt viscosity, control viscosity is the key processing, processing should be heat treatment, to eliminate internal stress. Can be made into precision size products. The molding processability of the PSF is shown below. (1) amorphous material, moisture absorption, water absorption rate of 0.2% ~ 0.4%, must be fully dried before use, and to prevent moisture absorption. Ensure that the water content is below 0. 1%. (2) The molding performance is similar to that of PC, and the thermal stability is poor, and the decomposition begins to appear at 360℃. (3) poor mobility, fast cooling, should use high temperature and high pressure molding. The mold should have sufficient strength and rigidity, set the cold material well, the flow channel should be short, and the gate size should be "2~1/3" of the wall thickness of the plastic part. (4) in order to reduce the internal stress of injection molded products, the mold temperature should be controlled at 100~140. After molding can take the annealing treatment of glycerol bath annealing treatment, 160 degrees C, 15min; Or take the air bath 160 degrees C, 14h. The annealing time depends on the size and wall thickness of the article. (5) polysulfone is close to Newton in the molten state, similar to polycarbonate, its fluidity is more sensitive to temperature, in 310~420 ℃, the temperature increased by 30 ℃, the fluidity is increased by 1 times. Therefore, the processing fluidity is mainly improved by increasing the temperature during molding.

PSU - Introduction
Polysulfone resin is a high performance thermoplastic resin with many excellent properties. The following is a description of the nature, use, formulation and safety information of Polysulfone resin:
Nature:
1. Polysulfone resin has good heat resistance, can maintain stability at high temperatures, and can withstand working temperatures up to 300°C.
2. It has excellent mechanical properties, high strength and hardness, and has good tensile and impact resistance.
3. Has excellent chemical stability, can resist the erosion of acid, alkali, solvent and other chemical substances.
4. It has the characteristics of low smoke, low toxicity and low volatility, and will not release toxic gases at high temperatures.
Use:
1. Polysulfone resin is widely used in high temperature environments in aerospace, automotive, electronics, chemical and other fields to manufacture high temperature resistant, corrosion-resistant and wear-resistant parts.
2. In the field of medical devices, Polysulfone resin is often used to make artificial joints, implantable devices and dental materials.
3. Due to its excellent insulation properties, Polysulfone resin is also commonly used in electrical and electronic fields to make high-temperature wire and cable insulation layers and electronic component substrates.
4. Polysulfone resin can also be used in the fields of hydraulic sealing materials, high temperature adhesives and coatings.
Preparation Method:
The main preparation method of Polysulfone resin is polymerization. A commonly used preparation method is the reaction of difluorobenzophenol and tetrafluorosulfuryl fluoride in an organic solvent by polymerization to form linear or cross-linked Polysulfone resin.
Safety Information:
1. Polysulfone resin is relatively safe under general conditions, but protective measures should be paid attention to during processing and operation to avoid inhaling its dust or harmful gases.
2. Studies have shown that long-term exposure to Polysulfone resin may cause skin allergic reactions, so it is recommended to wear protective gloves and other protective equipment during operation.
3. In the event of an accident, appropriate treatment measures should be taken immediately, such as quickly removing contaminated clothing and rinsing the affected area with plenty of water.
4. When handling or disposing of waste Polysulfone resin, correct environmental protection measures should be taken and local laws and regulations should be observed.
