- Description
- Cast Polyurethane is outstanding over other o-ring elastomers in abrasion resistance and tensile strength. Additionally, Cast Polyurethane surpasses the performance of Millable Polyurethane in its higher tensile strength.
- Key Uses
-
- Seals for high hydraulic pressures.
- Situations where highly stressed parts are subject to wear.
- Used for wheels, rolls, slurry parts, bumpers, couplers, and shock absorbers.
- Wiper seals for axially moving piston rods.
- Temperature Range
- Standard Compound: -30°F to +175°F
- Hardness (Shore A)
- 70 and 90
- Features
-
- With tensile strength of up to 6,000 psi, elongation of 350 to 650%, and exceedingly high abrasion resistance, the physical properties of Cast Polyurethane are among the best of all o-ring elastomers.
- Although they swell slightly upon exposure, Cast Polyurethane compounds feature excellent resistance to mineral-based oils and petroleum products, aliphatic solvents, alcohols and ether. They are also compatible with hydraulic fluids, weak acids and bases, and mixtures containing less than 80% aromatic constituents.
- Limitations
-
- Cast Polyurethanes are not recommended for exposure to concentrated acids and bases, ketones, esters, very strong oxidizing agents, pure aromatic compounds and brake fluids.
- With the exception of special compounds, they are also not recommended for exposure to hot water or steam.
