Hardened and Stiff Wheels in Cold Environments? PU Casters Excel in Low-Temperature Performance!
PU (polyurethane) casters maintain excellent elasticity even at temperatures as low as -40°C, unlike standard rubber wheels that harden and become brittle in the cold, leading to stiffness and poor rolling performance. Ideal for cold-chain logistics carts and refrigerated warehouse handling equipment, PU casters ensure smooth, reliable operation in freezing conditions—keeping your cold-chain operations efficient and uninterrupted.
