Beige PPS stick

pps due to molecular chain are alternately arranged by a benzene ring and sulfur atoms are inherently flame retardant without adding flame retardant can achieve UL-94-VO grade level. It is up to the limiting oxygen index of 44% -53%, and pvc similar to a self-extinguishing plastics, pps to ultraviolet rays is also very stable, when the surface is not irradiated or tacky decomposition phenomena. pps main problem is the poor toughness, low impact strength, melt viscosity stability is not enough. The main purpose of the application of pps pps pps main purpose is its excellent heat resistance as the center, taking into account its friction self-lubricating properties, chemical stability, dimensional stability, flame resistance and electrical insulation properties. Pps can be used in the chemical synthesis industry, transport, storage of materials of reaction tanks, pipes, valves, chemical pumps, etc., can be made in the mechanical center pps impeller blades, gears, eccentric wheels, bearings, clutches and wear parts; pps of The main purpose or in the field of electronic appliances, such as the production of transformers skeleton, high-frequency coil, plugs, sockets, wire rack, turn the contactor bulging sheet and various precision parts.
