PU90TA21 Datasheet

PU90TA21 is Canyon’s 90 Shore A translucent amber CanThane polyurethane formulated from a TODI-cured polycaprolactone system for extreme wear and high-pressure sealing applications. This premium polyurethane offers exceptional resistance to abrasion, wear, and hydrolysis while maintaining good flexibility and low compression set under sustained mechanical loads. With a service temperature range of -55°C to 130°C (-67°F to 266°F), PU90TA21 delivers reliable performance in demanding hydraulic, pneumatic, and mechanical environments. Its high tensile strength and elevated modulus make it especially well suited for O-rings, gaskets, seals, and molded components exposed to high pressure and repeated stress. Compare PU90TA21 to Disogrin 9250 for similar high-performance polyurethane sealing applications.

 

PU90TA21 is commonly selected for high-pressure seals, backup-style sealing elements, and wear components where long service life and resistance to hydrolytic degradation are critical. The polycaprolactone polyurethane chemistry supports extended durability in moist or fluid-rich environments compared to conventional polyurethane grades. Canyon Components offers PU90TA21 as a high-end polyurethane solution for O-rings and gaskets used in severe wear and pressure-driven applications.
