Polyetherimide (PEI) is a specialist polymer with specific properties:
- Heat Resistant polymer that can be extruded, but neither melts or drips when exposed to flame (FR).
- Various constructions have been developed, including utilising it in the World’s first monofilament to produce knitted 3D spacers.
- Other properties include high modulus, high chemical resistance, high dimensional stability (water & heat), high infrared transparency & low smoke toxicity.
