PEI (Polyetherimide)

1. Description:

PEI (Ultem® PolyEtherImide) is an amorphous high-performance polymer, with high mechanical efficiency, as well as very good thermal resistance and chemical stability (continuous operating temperature at approximately 180°C), high dimensional stability and creep strength. As it has the best torsional strength of all thermoplastic plastics, it has become a cheap substitute for small steel cutting parts. Guangzhou Engineering Plastics Industries (Group) Company has studied and applied this material in many industries for many years.

2. Characteristics:

1. High heat-resistant(long-term temperature resistant on180°C);

2. Good mechanical strength, high stiffness;

3. Excellent hydrolysis resistance,

4. Excellent physical inertness (thus suitable for contact with food);

5. Very good dimensional stability;

6. Good resistance to UV and high energy radiation ("γ"rays and"χ"rays);

7. Good electric insulation property.
