Omnia Plastica - Polyetherimide - PEI
Subcategory: Polyetherimide; Thermoplastic
Material Notes:
This high performance engineering plastic is a non-reinforced self-extinguishing amorphous polymer with high thermal, electrical and mechanical properties which are typical of a crystalline polymer.Features: - Resistance to high temperature
- Flame resistance: self-extinguishing, low oxygen index.
- Mechanical properties: high tensile stress, flexural strength, E.modulus
- Chemical resistance
- Electrical properties
Weak Point:The cost is higher than conventional engineering plastics. The shock resistance is not high. Application: - Electrical: very good insulating and dielectric properties. It is irreplaceable in many applications in this field thanks to its self-extinguishing property and low smoke emission.
- Mechanical: it is used for high performance components such as bearings, precision gears, etc. at low as well as high temperatures. The dimensional stability is excellent, as is the heat resistance.
- Chemical: good chemical and thermal properties.
- Food contact: physiologically inert
