The physical and chemical properties of German imported sulfone polyester boards and rods: Since there are no ester structural units in the molecular structure of polyethersulfone, polyethersulfone has excellent thermal properties and oxidation stability. It has been confirmed that the continuous use temperature of polyethersulfone is ℃ and meets the requirements of Class-A flame retardant (thickness is .). Polyethersulfone is resistant to stress cracking and is insoluble in polar solvents such as ketones and some halogen-containing hydrocarbons. Resistant to hydrolysis and most acids, alkalis, lipid hydrocarbons, alcohols, oils and lipids. The performance of the polymer can be improved by controlling its molecular weight or adding various reinforcing materials and fibers. The resin meets US requirements and can be used in parts that come into contact with food.
Although processed polyethersulfone is a high-temperature engineering thermoplastic resin, it can still be processed according to conventional thermoplastic processing technology. Injection molding, extrusion molding, blow molding, compression molding or vacuum molding can be used. High mold temperatures aid molding and reduce molding-induced stresses. Generally, the injection molding temperature is 3~3℃, and the mold temperature is ~℃. It is an amorphous resin with very small mold shrinkage and can be processed into products with high tolerance requirements and thin walls. Advantages: It has high mechanical and tensile strength from - to +℃, good dielectric properties, rigidity and hardness, and high impact strength at low temperatures. Excellent hydrolysis resistance and dimensional stability, self-extinguishing properties, low smoke properties, approved. It can be repeatedly sterilized at high temperatures, has high chemical resistance and radiation resistance, is high temperature and heat resistant, and is flame retardant. Disadvantages: Low concave impact strength, brittle, not resistant to polar detergents, and not resistant to weather. It will absorb ultraviolet rays and absorb moisture. When containing water, it will affect the tensile force, tension, and elastic modulus.
