PEI bars: Chinese polyetherimide rods, the English name of Polyetherimide, a non-crystalline plastic. Is an amorphous high performance polymer is amorphous PEI (polyether imide) manufactured out of plastic through the extruder from high temperature. PEI rod is currently used raw materials used by the U.S. GE (trade name Ultem), 1972 GE, the U.S. began research and development of PEI.
The main characteristics of PEI bars: the best of the high temperature and dimensional stability, and chemical resistance, flame retardant, electrical resistance, high strength, high rigidity. Not only high mechanical performance, but also has excellent heat resistance and chemical stability (continuous use temperature of about 170 ℃), and high dimensional stability and creep strength. At a high temperature high strength, high stiffness, wear resistance and dimensional stability. Do not add any additives have inherent flame resistance and low smoke level, oxygen index was 47%, the combustion grade UL94-V-0 level. PEI rod density 1.28 ~ 1.42g/cm3, glass transition temperature is 215 ℃, heat distortion temperature of 198 ~ 208 ℃, 160 ~ 170 ℃ in long-term use, allowing maximum use of intermittent temperature of 200 ℃. PEI has an excellent mechanical strength, electrical insulation, radiation resistance, high and low temperature and fatigue resistance and processability; addition of glass fiber, carbon fiber or other fillers can achieve the purpose of reinforcement and modification of thermoplastic plastics in its unique anti- torsional strength, making it a small steel cutting parts of the cheap alternative.
Rod applications PEI: PEI has an excellent overall balance rod performance, effectively used in electronics, automotive, motor and aviation workers to departments, and cultural life for traditional products and alternative supplies of the metal material. Generally used in micro-tools / Catering, analytical instruments, medical equipment, telecommunications, molded interconnect pieces (MTD), automotive lighting, aircraft interior parts, HVAC / fluid processing. PEI excellent hydrolysis resistance, so for medical surgical instrument handles, trays, fixtures, prostheses, medical appliances, dental mirrors and lamps.
