Product name: .Also known as: Sulfone Julong. Polyethersulfone resin () is a thermoplastic polymer material with excellent comprehensive properties and is one of the few special engineering plastics currently used. It has excellent heat resistance, physical and mechanical properties, insulation properties, etc., especially its outstanding advantages such as continuous use at high temperatures and stable performance in environments with rapid temperature changes. It has been widely used in many fields. The thermal thermal deformation temperature is ~℃, the continuous use temperature is ~℃, and the temperature index is ℃. Hydrolysis resistance can withstand ~℃ hot water or steam, and it is not corroded by acids and alkali at high temperatures. The temperature-based modulus of the modulus is almost unchanged from ℃ to ℃, especially above ℃, it is better than any kind of thermoplastic resin. Creep resistance In the temperature range below ℃, its creep resistance is the best among thermoplastic resins. In particular, glass fiber reinforced resin is better than some thermosetting resins. Dimensional stability, low linear expansion coefficient, and low temperature reliability are its characteristics. The characteristic is that the linear expansion coefficient of % glass fiber reinforced resin is only . ℃, and it can still maintain a value similar to that of aluminum until ℃. Impact Resistance Has the same impact resistance as polycarbonate. Unreinforced resin can be riveted, but it is sensitive to sharp cuts, so care must be taken in the design. Non-toxic in terms of health standards, it is recognized by the United States and also meets the requirements of Japan's Ministry of Health and Welfare Announcement No. It has self-extinguishing properties and has excellent flame retardancy without adding any flame retardant. It can reach grade (.) Chemical resistance. It is resistant to gasoline, engine oil, lubricating oil and other oils and Freon and other cleaning agents. It The solvent cracking resistance is the best among amorphous resins. However, it has poor resistance to polar solvents such as chlorine and chloroform, so care should be taken when using it. Advantages: It has high mechanical and tensile strength from to +℃ range, good dielectric properties, rigidity and hardness, and still has high impact strength at low temperature. 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.
