Sustadur® PET natural

PET

The semi-crystalline PET (Polyethylene Terephthalate)

In contrast to the generally known transparent (amorphous) PET, which is mainly used as a bottle material, Sustadur® PET is characterized in particular by its high mechanical strength, rigidity and hardness. Its very low thermal expansion and good tribological values are also remarkable. Compared to Sustarin® C, resistance to acids is increased, but resistance to hot water is significantly reduced. The natural-colored variant also provides an EU conformity for food contact.

Application Examples

药物分析中的磨损曲线应用

  • 耐化学性和良好的耐磨性

  • 高温条件下性能良好

Wear profiles for drug analysis

Wear profiles for drug analysis require materials that are chemically resistant and have good wear properties. Sustadur® PET is particularly suitable for these applications due to its properties and good performance at high temperatures.

Fluid chamber assembly

  • We supplied the assembly completely assembled to enable our customers to use it smoothly.
  • By developing specialized cutting and cleaning processes, we implemented effective measures to prevent stress cracking.
  • A closed pressurized assembly area was developed to eliminate dust contamination and ensure the quality of the assembly.
  • In addition, we package each assembly in an ISO Class 7 clean room to minimise potential contamination.
