Arizona Sealing Devices, Inc. Compound Designation: Poly Urth Mil
Standard Color: Black
Description: Millable Polyurethane is outstanding over most other O-ring elastomers in abrasion resistance and tensile strength.
Key Use(s):
Temperature Range: Standard Compound: -30° to +175° F.
Hardness (Shore A): 40 to 90
Features: 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. It also has good tear resistance.
Good low temperature flexibility is also a feature of many Millable Polyurethane elastomer compositions.
Limitations: 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.
