The New rheologically modified Ultradur® High Speed Is the first engineering plastic whose flowability has been significantly improved by the addition of nanoparticles. Ultradur® High Speed –created primarily for injection molding – reduces the injection pressures and the cycle times, thus achieving considerable cost benefits during processing.
Ultradur® High Speed is BASF’s particularly easy flowing PBT. A specially developed nanoparticle system has made it possible to significantly lower the melt viscosity of PBT ,resulting in a considerable improvement in the processing properties. Depending on the fiberglass content, Ultradur® High Speed flows at least twice as far as comparable standard Ultradur® grades (Figure1) The other characteristics of the material such as the mechanical properties of stiffness and strength, shrinkage behavior and thermal stability under heat are not affected by this modification.
The three advantages of Ultradur ®High Speed at a glance:
- 30% faster cycle times
- 50% higher flowability
- 30°C [54°F] Lower melt temperature
