PES plastic features

PES plastic is made of 4,4 '-disulfonyl chloride diphenyl ether in the catalysis of anhydrous ferric chloride, and diphenyl ether condensation, English simply called PES plastic. Refractive index 1.85, glass transition temperature 225℃, thermal deformation temperature 203℃ (1.82MPa). The heat resistance is between polysulfone and polyaromatic sulfone, and the long-term use temperature is 180-200 ℃. Excellent aging resistance, up to 20 years at 180 ℃. Good fire resistance. Even if it burns, it doesn't smoke. The creep resistance is good, and the strain change under 150 ℃ and 20MPa pressure is only 2.55%. The following PPA plastic manufacturer Xiaobian for you to introduce:

Good chemical resistance, in addition to chlorinated hydrocarbons, ketones, acids other than general organic solvents. It is stable to general acids, bases, aliphatic hydrocarbons, fats and alcohols. Good resistance to steam and superhot water (150-160 ℃), poor ultraviolet resistance, excellent electrical performance, fire resistance grade V-O. Relative density l.37-1.5l; Water absorption (23℃ / 24h) 0.43%; Tensile strength 843-124.5 (23℃), 41.2-59.8 (180℃); Elongation 40-80%; Bending strength 129.4-171.5MPa; Impact strength (notch) 78.4 ~ 85.3J/m; Rockwell hardness R120-134. PES plastic resin (PES plastic) is a thermoplastic polymer material with excellent comprehensive properties developed by ICI in 1972, and is one of the few special engineering plastics currently applied. It has excellent heat resistance, physical and mechanical properties, insulation properties, etc., especially with the outstanding advantages of continuous use at high temperatures and the ability to maintain stable performance in the environment of rapid temperature changes, and has been widely used in many fields. The thermal variation temperature is 200 ~ 220℃, the continuous use temperature is 180 ~ 200℃, and the UL temperature index is 180℃. It can withstand 150 ~ 160℃ hot water or steam, and is not attacked by acid and alkali at high temperature. The fundamental modulus is almost unchanged from -100 ° C to 200 ° C, especially above 100 ° C, which is better than any thermoplastic resin. In the temperature range below 180℃, its creep resistance is one of the most excellent thermoplastic resins, especially glass fiber reinforced PES plastic resins than some thermosetting resins. The linear expansion coefficient is small, and its temperature reliability is also small. It is characterized by 30% glass fiber reinforced PES plastic resin, whose linear expansion coefficient is only 2.3×10 /℃, and it can still maintain a similar value to aluminum until 200℃. It has the same impact resistance as polycarbonate. Unreinforced resin can be riveted, but it is more sensitive to sharp cuts, so the design should be paid attention to. In terms of health standards, it is recognized by the United States FDA, and also meets the requirements of the Japanese Ministry of Health and Welfare No. 434 and No. 178 announcement with self-extinguishing, without adding any flame retardant that has excellent flame resistance, up to UL94V-0 class (0.46mm) PES plastic resistant to gasoline, oil, lubricating oil and other oils and freon cleaning agents, Its resistance to solvent cracking is the best among amorphous resins. However, it can be dissolved in polar solvents such as chloroform and acetone, and should be paid attention to when used.

PES plastic has the advantages of solder resistance, dimensional stability, resistance to various cleaning agents, inlay metal parts, and good adhesion to cyclooxy resin, etc., which are used as H-class insulating materials in the field of electronics and electrical appliances. The main products that have been developed are coil skeleton, casing and base of potentiometers, blower parts, printed circuit board, button switch, thyristor insulator, electric tool motor insulator, printer, fan, relay coil skeleton, DIP switch, various connectors and so on. Films of different thicknesses can also be made by extrusion forming method for various electronic devices and electrical products. PES plastics have been widely used in places where general resins cannot meet the requirements by virtue of their advantages of high temperature creep resistance, dimensional stability, oil resistance and good toughness. The main products that have been developed are various machine levers, handles, brackets, etc., X-ray device observation glass, chain saws, insulators for agricultural engines and carburetors, piston rings, heat-resistant balls, gears, copier parts, camera parts, projector parts, industrial hair dryer covers, automobile air conditioning parts, arc welding gun handles, etc. Various analytical instrument components, etc. The main use of PES plastic in the wide temperature range of -100℃ ~ 190℃ rigidity and dimensional stability, high temperature creep resistance, resistance to gasoline, diesel, all kinds of oil and other advantages. The products have been developed are various bearing retainers, bearing shingles for brake shafts, noise cancelers for igniters, engine gears, coil frames for carburetors, mirrors for fog lamps, thrust rings, etc. The main use of PES plastic, which can maintain excellent creep resistance, rigidity and size stability in hot water or steam at 160 ° C. The main products developed are valves for hot water and steam, insulators for anti-corrosion electrodes, components for temperature sensors, pump bodies and impellers for various liquid and powder pumps, radiator valves, parts for ultrafiltration devices, etc. Edit this paragraph medical equipment, food processing machinery field

PES plastic can be sterilized by steam sterilization, dry steaming (180℃) sterilization, V-ray sterilization and other sterilization methods, and can be resistant to repeated disinfection. The main products developed are contact lens sterilizers, dental drill handles, surgical containers, syringes, valves and tubes for the food industry.
