Product features

DOCAPET GLD130 TF is an excellent PET composite thanks to the evenly distributed solid lubricant additive. Not only does it have better wear resistance, but its sliding properties are also superior to other engineering plastics. As a consequence, its load carrying capacity "P×v" is also higher compared to PA, POM and natural PET materials.

product family features

Polyethylene terephthalate, or PET, has significantly better mechanical properties than POM, which is similar in many respects. Its advantages offset its slightly higher price than the average price level of POM. Its outstanding wear resistance, sliding properties, strength make it suitable for applications with high mechanical stress, excellent dimensional stability, high hardness and good machinability.

The harshness of the basic version is eliminated by the addition of a lubricant - Teflon - which gives PET TF (Teflon PET or lubricated PET) even better properties and easier machining.

It is also often referred to as the ZX100 (or ZX-100). In terms of its versatility, apart from the machinery industry, it is also used in the food industry, although it is not hydrolysis resistant. It is available in both plate and rod formats in a wide range of sizes.

DOCAPET GLD130 TF

Some important features

  • High strength (yield strength 78-90 MPa, 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)
  • Favourable creep resistance (24-26 MPa tension for 1% stretching over 1000 hours)
  • Application temperature range: -20°C to +110°C permanently
  • Very high hardness (Rockwell: M 94 - M 96)
  • Good fatigue strength and damping capacity
  • Virtually no swelling (negligible) when wet
  • Physiologically neutral, may come into contact with food and medicines
  • Very good wear resistance compared to PA and POM in non-abrasive environments

Main areas of application

Heavy-duty sliding elements; plain bearings; fine mechanical dimension machine elements; sliding pipes; distribution pistons; pump elements; insulating elements in the electrical industry; rollers; gears, etc.

Machining technology

Chipping (turning, milling, drilling, boring, reaming, sawing): virgin (unloaded) PET can be machined at low cutting forces and cooled to avoid residual stress. The minimum value of cuts and chamfers is 1-2 mm. Conventional tools can be used, but only with a sharp finish. Cooling is strongly recommended, the applicable speeds are e.g.: v = 200-400 m/min for turning, v = 150-300 m/min for milling, v = 50-80 m/min for drilling.

Gluing and welding: feasible.
