HYDEX® 202EZ RTPU Rod, Unground

HYDEX® 202EZ is a rigid thermoplastic polyurethane (RTPU), an amorphous engineering polymer that shares the chemistry of cast urethane elastomers but none of their softness. It pairs a notched Izod impact strength of 10 ft-lb/in with 9,000 psi tensile strength at yield and 80 percent elongation at break, so parts absorb shock and deform rather than shatter. Modulus of elasticity is 240,000 psi in tension and 260,000 psi in flexure, heat deflection temperature is 280°F at 264 psi, and the polymer withstands chemical attack across a pH range of 2 to 14 with only 0.12 percent moisture pickup in 24 hours.

It is specified for chemical process hardware, pharmaceutical and medical fixtures, oil and gas components, and shop tooling where a part sees repeated impact and aggressive wash-down chemistry at once: pump and valve parts, wear pads, guide rails, scraper blades and jig bodies. The base resin carries NSF/ANSI Standard 61 certification for potable water contact. Stock shapes cut cleanly with standard carbide tooling and hold dimensions well because residual stress is low. The trade-off is stiffness, since a 240,000 psi modulus deflects more under sustained load than glass-filled or crystalline alternatives.
