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.
