Millathane HT Formulations  New!

Millathane HT is a polyester, millable polyurethane which has the ability to withstand elevated temperatures. One typical shortcoming of polyurethanes in general is a loss of physical properties at temperatures over 180ºF (82ºC); Millathane HT has overcome this weakness.

MILLATHANE HT can withstand a continuous temperature of 250°F (121°C) and still retain the excellent physical properties of polyurethane.

MILLATHANE HT can be processed and cured by use of conventional rubber manufacturing
equipment and techniques to yield finished urethane rubber parts. Compounds prepared
from MILLATHANE HT can be vulcanized with either sulfur or organic peroxide based systems.

MILLATHANE HT has the following outstanding
characteristics:

  • Heat aging resistance
  • Low temperature flexibility
  • Abrasion resistance
  • Tear strength
  • Ozone and weathering resistance
  • Oil and fuel resistance
  • Processing ease
  • Steam curable (with protection)

Millathane HT Premilled contains 1.5 phr of a polycarbodiimide (Millstab™ P) as a stabilizer for improved hydrolysis resistance and heat aging properties.
