high strength: 78–90 MPa (yield stress, tensile strength),
toughness ( grooved Charpy ): 3.5 kJ/m2 – 50 kJ/m2,
very good sliding properties: m = 0,1–0,3 (dry sliding on smoothed and ground steel),
favorable creeping resistance: 24–26 MPa tension for 1% extension in 1000 h,
temperature range for application: from -20°C to +115°C,
very high hardness (Rockwell): M 94 – M 96,
good fatigue resistance and damping capability,
virtually no expansion in the presence of moisture (negligible),
physiologically neutral, it can come in contact with food and medicine,
very good wear resistance in comparison with the PA and POM materials, in a non-abrasive environment,
density: 1,4 kg/dm3
Cutting (turning, milling, drilling, reaming, sawing): in order to avoid permanent tension, it has to be cut using small cutting forces and cooling. The minimum value of rounding and break-off can be 1 – 2 mm. Traditional tools can be used but only in sharp design. Cooling is strongly recommended, the applied speeds can be for example v = 200–400 m/min for turning, v = 150–300 m/min for milling, v = 50–80 m/min for drilling.
Adhesive bonding and welding: feasible.
DOCAPET (PET – Polyethylene terephtalate) Products
Unfilled PET product with special characteristics and crystallite structure, which is especially suitable for precision machining. It has a large mechanical load-carrying capacity, with very good sliding and wear characteristics.
Due to the evenly distributed lubricant component, DOCAPET TF is an excellent PET composite. Not only its wear resistance is better, but even its sliding characteristics stand out among the other technical plastics. Consequently, even its "P×v" load carrying capacity is greater than the PA, POM and "natural" PET materials.
