A polyurethane stick, commonly known as a PU rod or round bar, is a solid cylindrical material used in a wide range of industrial applications. It combines rubber-like elasticity with excellent wear resistance, making it suitable for both structural and dynamic components.

Polyurethane sticks are widely used as raw materials for machining parts such as rollers, bushings, spacers, and wear components. Compared to traditional rubber or plastic rods, PU rods offer longer service life, better load-bearing capacity, and superior abrasion resistance.

Key Features

Excellent Wear Resistance: Suitable for high-friction environments.

High Elasticity: Provides flexibility and shock absorption.

Strong Mechanical Properties: Maintains performance under load.

Good Machinability: Can be cut, drilled, and turned easily.

Oil and Chemical Resistance: Works well in industrial conditions.

Long Service Life: Reduces maintenance and replacement costs.
