PAS RTP 1685Use performance
English name: Polyarylsulfone (PAS)
1, the history of the development of
Poly aryl sulfone in 1967, developed by U.S. company 3M and sold to Astrel360 grades, production and marketing rights will be transferred to the Carborundum Company, by the company in the worldwide production and sales still Astrel360 grades.
2, the main production methods
Astrel 360 polyarylsulfone by 4,4 '- carbonyl dichloro-diphenyl ether and biphenyl Friedel-Crafts polymerization reaction.
3, the physical and chemical properties
Astrel 360 polyarylsulfone typical characteristics of heat-resistant, long-term aging in air temperature of 260 ° C conditions.
4, the molding process
Polyarylsulfone can be injection, extrusion or compression molding technology for processing into products. But the poly (aryl sulfone) having a high melt viscosity, so there are special requirements on the processing equipment, ships to meet the processing temperature of 400 ° C to 425 ° C using a dedicated processing device. The pressure requirements for the 140 ~ 210MPa (20300 ~ 30450psi), a mold temperature of 230 to 280 ° C.
5, application areas
Polyarylsulfone mainly used in electrical, electronics industry, mostly for military products, multi-plug contacts, printed circuit board substrate and socket. These parts require having good mechanical properties, thermal properties and chemical resistance.
