China Unreinforced PEI Pellet Amber Yellow Transparent plastic resin Polyetherimide Virgin resin Ultem PEI Natural

Unreinforced PEI Pellet Amber Yellow Transparent plastic resin/Polyetherimide Virgin resin Ultem PEI Natural
1, PEI (polyetherimide) is an amber transparent solid with good flame retardancy and low smoke, and the burning grade is V-0.
2, PEI has a strong high temperature stability.
High temperature resistance, heat distortion temperature up to 220 ° C, can be used for a long time at -160 to 180 ° C operating
temperature.
3, good hydrolysis stability, high temperature resistance, steam resistance;
4, polyetherimide has good UV resistance, Y-ray performance.
The main advantage:
Continuous working temperature range (-200--170 degrees long-term work), glass transition temperature and thermal denaturation
temperature close to, melting point up to 330 degrees; still maintain high mechanical strength, high hardness, high creep
resistance at low temperature / high temperature, Good toughness;
Outstanding anti-precipitation (suitable for use in sterilization rooms that utilize steam sterilization);
It is not easy to breed bacteria, and is often used in food processing industry; it has excellent high radiation resistance and
can transmit infrared light and microwave radiation;
Good electrical insulation and good plating performance;
The wide temperature (-200--170 degrees) range maintains a stable dielectric constant and loss factor.
