Features plastic glasses. 1, plastic glasses, plastic titanium PEI than TR90 plastic, but also light. More metallic, look more upscale and elegant. The TR90 plastic titanium exterior looks no different from ordinary plastic. No high-end taste. 2 PEI frame, plastic glasses, beautiful and lightweight anti-acid PEI, the average frame weighs only about 9 grams, only one-third the weight of ordinary frames. no longer afford to nose ears. 3, pliable plastic glasses with strong performance 360 ° bend, thus ensuring the integrity of the spectacle frame. This feature PEI, so that people who love sports, do not worry about glasses deformed due to the collision, do not be afraid of a good move cute baby grab and pull the glasses deformed tired down to sleep in the bed or on the table is not afraid glasses deformed. 4, Plastic glasses, like steel frames, like ultra-thin, surface hardness as steel, like with a nail or something sharp draw, it will not leave marks. Physical picture is shown below: Product Name: polyetherimide Product Type: PEI brief overview: PEI (polyetherimide) has excellent mechanical properties, electrical insulation properties, radiation resistance, high temperature resistance and abrasion performance, and through the microwave. PEI both excellent high temperature mechanical properties and wear resistance, it can be used to make pipes steering valve valves. Due to high strength, flexibility and heat resistance, PEI is a good coating and film-forming material can be formed for the electronics industry, coatings and films. The main features of the continuous operating temperature range (-200--170 degree of long-term work), the glass transition temperature and thermal denaturation temperature close to the melting point of up to 330 degrees at low / high temperature and still maintain high mechanical strength, high hardness, high creep resistance good toughness outstanding anti-precipitation of (suitable for use in sterilization by steam sterilization chamber); easy to breed bacteria, commonly used in the food processing industry high radiation resistance is excellent, you can microwave radiation through infrared light; electrical insulation, good plating performance over a wide temperature (-200--170 degrees) range stable dielectric constant and dissipation factor can not be tested by SMT reflow soldering major applications in the electronics industry: connectors, general and micro-relay housings, circuit boards, coils, soft circuits, mirrors, high-precision dense fiber-optic components, high temperature insulation panels Automotive industry: connectors, high power lights and lights, external temperature control compartment of the vehicle sensors, control of air and fuel mixture temperature sensors, medical equipment and other .
