ULTRALAST® TPUs are taking
Elastomers to New Extremes

ULTRALAST® Thermoplastic Polyurethane elastomers offer premium performance versus standard TPUs and other high performance elastomers in extreme applications where heat resistance, chemical resistance and superior dynamic mechanic properties are required. Applications requiring cut and tear strength, compression set, and abrasion resistance benefit from using ULTRALAST® TPUs.

ULTRALAST® TPUs are made possible with Chemtura’s patented “Low Free Monomer” (LF) technology. This technology provides a unique designed morphology that is tailored to perform under extreme conditions of temperature (-80˚C to 165˚C) and harsh environments.

This brand of specialty elastomers delivers a combination of thermoset-like product performance with the benefits of traditional, high-productivity thermoplastic processing.

ULTRALAST® TPUs are available in a broad selection of hardness for a wide range of markets and applications.

Performance advantages of ULTRALAST<sup>®</sup> TPU

Performance advantages of ULTRALAST® TPU

ULTRALAST® TPUs are characterized by their excellent physical and dynamic performance. They provide enhanced tear strength and compression set and excellent chemical resistance and temperature resistance. This brand of specialty elastomers has better molecular structure. This improved structure leads to:

  • Superior Dynamic Properties
  • Increased Durability in Harsh Use Conditions
  • Higher Temperature Performance
  • Better Chemical Resistance
  • Longer Component Life
  • Better Abrasion, Tear Resistance, and Wear
  • Easier Processability

Processing advantages of ULTRALAST® TPU

Another advantage of the more structured morphology of ULTRALAST® TPUs is better processing, as compared to standard TPUs and other high performance specialty elastomers. ULTRALAST® TPUs offer:

  • Lower required processing temperatures compared to conventional TPU, by as much as 20-50˚C, for reduced cycle times, while providing higher in use temperatures
  • Improved thermal stability, easier demolding, and better aesthetics
  • Injection molded and extruded into complex geometries
