  • Excellent thermal and oxidative stability,
    high resistance to heat deflection (continuous temperatures of up to 100 °C)
  • Very good resilience (spring properties)
  • High dimensional precision and stability
  • Excellent chemical and hydrolysis resistance
  • Good processability

Explosionsgrafik Inhaler.jpg
The pairing of components made of Ultraform® PRO and Ultradur® PRO Offers extraordinary tribological synergy effects.

Tribological modified Ultraform® PRO TR and Ultradur® PRO TR grades are including a special lubricant which offers improved siding properties in terms of exceptional low friction and low wear properties for complex mechanical devices.

  • No squeaking or noise while being used
  • Suitable for dry run applications
  • No external lubrication required - elimination of post siliconization process steps in production
  • No running-in effects
  • Smooth-running operation from the beginning
  • Low breakaway forces
