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
