Polyetherimide (PEI)

Polyetherimide (PEI) is a high-performance thermoplastic that belongs to the group of heat-resistant plastics. It is processed primarily via injection molding. PEI components can be bonded using epoxy, polyurethane or silicone glue.

It is mostly made into plastic parts for electronics or the aircraft industry, as it offers high flame retardancy and impact resistance for fiber composite structures.

Membranes made of polyetherimide are successfully used in many industries because of their excellent mechanical, and thermal resistance, good film-forming capacities and relatively cost-efficient production. The material’s surface properties can be specifically modified by plasma treatment to range from hydrophilic to hydrophobic
