Polyetherimide is a modified polyimide that is an amber transparent solid. It has inherent flame retardancy and low smoke without any additives. Its oxygen index is 47% and its burning rating is UL94. -V-0 grade, with a density of 1.28~1.42g/cm3.

Main features

1.High temperature resistance: working temperature 180 ° C

2.Good toughness and rigidity

3.Good hydrolysis resistance, electrical insulation and radiation resistance

4.Higher hardness and good abrasion resistance

5.Outstanding electrical performance

Application area

1.PEI's excellent comprehensive balance performance has been successfully used in the industrial sectors such as electronics, electrical machinery, aviation, and automotive, and can be used as a metal substitute for traditional products and cultural and living supplies.

2.Applications in the electrical and electronics industries include high-strength and dimensionally stable connectors, common and miniature relay housings, circuit boards, coils, flexible circuits, mirrors, and high-precision dense fiber optic components.

3.Impact-resistant sheet Ultem1613 is used for various parts of aircraft, such as portholes, nose parts, seat backs, inner wall panels, door coverings, etc.

4.Automotive applications such as manufacturing high-temperature connections, high-power lights and indicators, air-conditioning temperature sensors and sensors for controlling air and effective combustion temperatures, vacuum pump impellers, sockets for stills operating at 180 ° C, non-lighting Reflector of anti-fog light.

5.PEI foam is used as a thermal and sound insulation material for transportation machinery and aircraft.

6.PEI has excellent hydrolysis resistance and is therefore used as handles, trays, clamps, prosthetics, medical lamp reflections and dental appliances for medical surgical instruments.

7.In the food industry, it is used as a tray for product packaging and microwave ovens.

8.PEI has both excellent high temperature mechanical properties and abrasion resistance, so it is used to manufacture valve parts for water transfer steering valves.
