PEI also has very low shrinkage and good mechanical properties such as the direction. Glass fiber, carbon fiber or other fillers can be modified to achieve the purpose of enhancement; and other engineering plastics can also be composed of heat-resistant polymer alloy frame PEI, long-term use at -160 ~ 180 ℃ operating temperature. Underwriters Laboratories provides long-term use temperature polyetherimide resin is 338T and 356T (according to grade), flame rating to UL94V-0 (10 mil thickness.) Oxygen index of 47, in line with aircraft polyetherimide FAA flame and heat release requirements lean pieces of material standards. Its glass transition temperature of 419F, and allowing under intermittent use in 392F, at higher temperatures, short-term drift. In 356T, the stretching temperature and flexural modulus at 41 and 2068MPa or more, respectively. With glass fiber, carbon fiber reinforced material near the glass transition temperature, has a higher strength and stiffness. The company are real pictures taken: PEI material properties of plastic materials, plastic glasses is a very light material, the general application for aviation materials, then it has the best temperature and dimensional stability PEI plastics, and chemical resistance, flame, electrical resistance, high strength, high stiffness and other characteristics, it is applied electronics, medical, chemical and other fields. Like Apple phone shell PEI, PEI particulate material is steel, because it is difficult to scratch. In 2009, in Japan, South Korea, some people began to experiment with the plastic material for the glasses, 2011 Optical Fair in New York, Hong Kong Optical Fair and other large exhibition of glasses plastic glasses began to show.
