PEI: polyether imide

English name: polyetherimide,

Definition of PEI: a class of polymers with aromatic ether group and imide group as structural characteristic groups, which are directly connected with aromatic imide group benzene ring and repeat unit. It is usually synthesized by nucleophilic substitution polymerization of aromatic diphenol and dinitrodisimide monomer. It is a thermoplastic engineering plastic with excellent comprehensive properties.

characteristic

1. High temperature resistance (HDT over 200℃, UL continuous application temperature over 170℃)

2. Excellent flame retardant (oxygen index > 4.7, low smoke emission and UL94V-0/5V)

3. No need to add flame retardants

4. Excellent electrical performance (stable dielectric constant and dielectric loss and high dielectric strength in a wide range of frequencies and temperatures)

5. Excellent chemical resistance and radiation resistance

6. Unique strength and rigidity

7. Transparency

Processing technology

Drying treatment: PEI has hygroscopic properties and can cause material degradation. The humidity should be less than 0.02%. The recommended drying condition is 150℃ for 4 hours.

Melting temperature: 340 ~ 400℃ for common materials; The reinforced material is 340 ~ 415℃.

Mold temperature: 107 ~ 175℃, recommended mold temperature is 140℃.

Injection pressure: 700 ~ 1500bar.

Injection speed: Use the highest injection speed possible. 

Scope of application

Because PEI has excellent comprehensive balance performance, effective application in electronics, electrical machinery and aviation industry departments, and used as traditional products and cultural life products of metal substitute materials. Using PEI instead of metal to fabricate fiber optic connectors can optimize component structure, simplify manufacturing and assembly steps, and maintain more accurate dimensions. For automotive applications, such as high temperature connectors, high power lights and indicators, sensors to control the external temperature of the vehicle cabin (air conditioning temperature sensors) and sensors to control the temperature of air and fuel mixtures (effective combustion temperature sensors). It can also be used as a vacuum pump impeller resistant to corrosion of high temperature lubricating oil, ground glass joint (junction) of distillate operating at 180℃, and non-illuminating anti-fog lamp mirror
