PU 開發

With the opening of the Polyurethane (PU) Laboratory in 2001, Trelleborg Sealing Solutions made clear the importance of this material group, for dynamic sealing technology. Since then, we have been able to increase our efficiency and improve our performance in the field of PU development.
At present, we can offer our customers

  • The selective combination of specific materials in order to increase the performance of our standard products
  • Development focused on customer's requirements, such as custom PU formulations
  • All processes and resources necessary to tackle the development of high-performance materials in our Polyurethane Laboratory:
  1. Chemical processing reactor with the option of regulated temperature control - for use in formation of the pre-polymer
  2. Cross-linking station equipped with a high-speed agitator - For blending of the pre-polymer with the cross-linking agent
  3. Temperature controlled casting plate - To aid solidification of the mixture
  4. Granulating machine to comminute the semi-finished PU material
  5. Specially designed tools for series-identical fabrication of prototypes and testing specimens used for laboratory investigation
  6. An injection-molding machine which is identical with the machine used in series production featuring additional software options for Quality Assurance and process adaptability surveys.
  7. Highly qualified staff with years of experience
  • We can produce thermoplastic polyurethanes (TPUs) based on their chemical, physical, tribological and mechanical properties on a semi-industrial scale by creating task-adapted molecular structures.
  • The three basic components, isocyanate, polyol and cross-linking agent, are carefully varied during chemical synthesis. Additives are also incorporated in some cases.

With these three constituents we can take influence on:

  • The damping properties
  • The permanent set
  • Rigidity
  • The Young's modulus
  • Resistance against extrusion
  • The behavior at high and at low temperatures
  • Chemical resistance
  • Abrasion behavior

The formulations and measurement readings of the material tests are precisely recorded. We can, for example, construct stress-elongation-curves derived from the tensile tests by applying our Finite Element Method (FEM) calculation system. We can therefore simulate the sealing behaviour for certain criteria, so that based on predefined piece-geometry, conclusions may be drawn regarding the optimum material.

The future generations of improved TPUs may be typically found in the following application fields:

  1. Seals for rods and pistons used in pneumatics and hydraulics
  2. Scraper elements
  3. Rotary seals
  4. Valves
  5. Machined parts used in engineering, especially with multifunctional feature
