tensile stress at yield: min.30 MPa,
modulus of elasticity: min. 1300 MPa,
chemically resistant, weather resistant,
temperature range of use: from –20ºC to +90ºC
hardness: 70 MPa (ball indentation H961/30),
density: 0,91 kg/dm3,
lower purchase price (in comparison with other technical plastics),
electric insulating capability, even in wet medium.
Cutting (turning, milling, drilling, sawing): only traditional metalworking – or in certain cases, woodworking tools – carbon steel, rapid steel, hard metal, diamond can be used only in sharp design. Cooling is recommended, which allows high cutting rates, e. g. v = 200 –400 m/min for turning and milling, v = 50 –100 m/min for drilling.
Adhesive bonding: hard to apply.
Welding, forming: feasible.
