PU Polyurethane Solid Round Rod Bar Stick 20mm-100mm Elastic Shock Absorber

Product Introduction of Polyurethane (PU) Rod

Polyurethane (Polyurethane, abbreviated as PU) rod is an industrial bar-shaped material made from high-performance polyurethane elastomer. Through unique chemical formulations and molding processes, it combines the elasticity of rubber with the strength of plastic, making it an ideal choice for numerous demanding application scenarios.

1. Core Material

Polyurethane is a high-molecular polymer formed by the polymerization reaction of polyols and isocyanates. By adjusting raw material formulations, additives, and process parameters, the physical properties of the final product can be precisely controlled, thereby producing PU rods with varying hardness, elasticity, and wear-resistant characteristics.

2. Main Advantages

Thanks to its unique molecular structure, polyurethane PU rods exhibit outstanding comprehensive properties:

• High Resilience and Flexibility: Capable of quickly returning to their original shape after withstanding significant impact, pressure, or bending, absorbing energy, and effectively reducing vibration and noise.

• Exceptional Wear Resistance: Its wear resistance is over 5-10 times that of natural rubber, even surpassing many metal materials, making it particularly suitable for high-friction environments.

• Excellent Load-Bearing and Tear Resistance: Maintains good elasticity even at high hardness, with strong load-bearing capacity and superior tear resistance.

• Good Oil and Corrosion Resistance: Offers good resistance to most mineral oils, lubricants, and solvents, is ozone-resistant, and has slow aging rates.

• Wide Hardness Range: Shore hardness can range from Shore A 60 to Shore D 80, providing a variety of options from soft to rigid to meet different needs.

• Superior Thermal Insulation and Electrical Insulation: Serves as a good thermal and electrical insulating material.

• Ease of Machining: Can be secondary processed using conventional machine tools such as lathing, milling, drilling, and cutting, facilitating the production of various precision parts.

3. Primary Applications

Due to its versatility, polyurethane PU rods are widely used across various industries:

• Industrial Sector:

  • Sealing and Buffering: Used to manufacture high-performance seals, oil seals, gaskets, buffer blocks, shock absorber pads, etc.

  • Power Transmission and Conveyance: Used for conveyor rollers, drive wheels, gears, couplings, scraper blades, and other wear-resistant components.

  • Tools and Fixtures: Serves as machine tool liners, non-metallic hammers, flexible contact parts for jigs and fixtures.

• Engineering Machinery and Automotive: Used for suspension bushings, bearing liners, protective sleeves, screen plates, wear-resistant linings, etc.

• Sports, Leisure, and Equipment: Manufacture of pulleys, casters, fitness equipment handles, equipment cushioning elements, etc.

• Design and Prototyping: Due to its ease of machining, it is often used by designers and engineers to create functional prototypes, models, and custom parts.

• Other Fields: Also used for high-performance rollers, mining screening equipment, wear-resistant pipe linings, etc.
