Millable Polyurethane is outstanding over most other o-ring elastomers in abrasion resistance and tensile strength.
Key Uses
  • Seals for high hydraulic pressures.
  • Situations where highly stressed parts are subject to wear.
Temperature Range
Standard Compound: -30°F to +175°F
Hardness (Shore A)
40 to 90
  • Millable Polyurethane offers superior seal performance in hydraulic situations, where high pressures, shock loads, or abrasive contamination is anticipated.
  • Millable Polyurethane possesses chemical compatibility similar to that of Nitrile, offering good resistance to petroleum-based oils, hydrocarbon fuels and hydraulic fluids, the oxidizing effects of ozone, and the aging effects of sunlight.
  • Good tear resistance.
  • Unless specially compounded, at elevated temperatures Millable Polyurethane begins to soften, losing its physical strength and chemical resistance advantages over other polymers.
  • Tending to rapidly deteriorate when exposed to concentrated acids, ketones, esters, chlorinated and nitro hydrocarbons, Millable Polyurethanes are also prone to hot water and steam degradation.
