Virgin PEI Glass fiber filled PEI Compound resin
What is PEI pei in plastic materials ?
Polyetherimide, PEI, is an amber transparent solid with inherent flame retardant and low smoke without any additives. It has an oxygen index of 47%, a combustion class of UL94-V-0, and a density of 1.28 to 1.42g/cm3. PEI has strong high temperature stability, even non-enhanced PEI, still has good toughness and strength. Therefore, the superior thermal stability of PEI can be used to make high temperature and heat resistant devices. It has excellent mechanical properties, electrical insulation properties, radiation resistance, high and low temperature resistance and wear resistance, and can be transmitted through microwave. PEI also has good flame retardancy, resistance to chemical reactions and electrical insulation properties. The glass transition temperature is very high, up to 215ºC. PEI also has a very low shrinkage rate and good isodirectional mechanical characteristics. Adding glass fiber, carbon fiber or other fillers can achieve the purpose of strengthening modification; It can also be composed of heat-resistant polymer alloys with other engineering plastics, which can be used for a long time at the working temperature of -160~180 ° C.

Injection conditions:
Drying treatment :PEI has hygroscopic properties and can cause material degradation. The humidity should be less than 0.02%. The recommended drying condition is 150ºC for 4 hours.
Melting temperature: 340~400ºC for common materials; The reinforced material is 340~415ºC.
Mold temperature :107~175ºC, recommended mold temperature of 140ºC.
Injection pressure :700~1500bar.
Injection speed: Use the highest injection speed possible.
Tip for Machine selection :
PEI resin can be molded on most standard injection moulding machines. A reciprocating screw injection molding machine is recommended.
Replacing metal to manufacture fiber optic connectors optimizes component structure, simplifies its manufacturing and assembly steps, and maintains more accurate dimensions. For automotive applications, such as high temperature connectors, high power lights and indicators, sensors to control the external temperature of the car cabin, and sensors to control air and fuel mixtures. It can also be used as a vacuum pump impeller resistant to high temperature lubrication, a ground glass joint (socket) of a still operating at 180 ° C, and a mirror for non-illuminated anti-fog lamps.
