The PLASTMASS™ PEI plastics are resistant to various weather influences and work under a constant operating temperature of 180 °C. The Kunststiff can even withstand temperatures of up to 200 °C for a short time. At the same time, the plastic is resistant to aggressive chemicals. When burned, the PLASTMASS™ PEI plastic emits a small amount of heat and its fumes are the least toxic. In the Izod impact test, the plastic cannot be destroyed by hitting a notch. PLASTMASS™ PEI has a tensile strength of 101 MPa.
