Millathane® HT Premilled*

A Sulfur and Peroxide Curable Polyester Millable Polyurethane

Millathane HT is a polyester millable polyurethane which has excellent frictional properties for applications such as rollers for paper handling applications.

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 characteristics:

  • Excellent frictional characteristics
  • Good heat aging characteristics
  • Low temperature flexibility
  • High abrasion resistance
  • Excellent ozone and weathering resistance
  • Oil and fuel resistance
  • Processing ease
