Hangzhou Bright Rubber Plastic Product Co., Ltd. is one of the leading manufacturers and suppliers of colored cast polyurethane rod in China. If you're going to buy colored cast polyurethane rod made in China, welcome to get more information from our factory. We also accept customized orders.
Material & Properties
This rod is manufactured from high-quality polyurethane elastomer, which uniquely bridges the gap between plastics and rubber. It provides the stiffness, load-bearing capacity, and impact resistance of plastic, combined with the flexibility and elasticity of rubber. This hybrid nature allows the material to absorb high levels of shock and vibration while resisting deformation under heavy loads. The material is also exceptionally resistant to tearing and abrasion. It offers excellent dimensional stability and retention of physical properties over a wide range of operating temperatures.
Abrasion & Impact Resistance
The most prominent advantage of polyurethane is its outstanding wear and abrasion resistance, which significantly outperforms standard rubber, nylon, and other plastics. Its exceptional toughness allows it to withstand continuous friction without developing deep grooves or losing its dimensional accuracy. The material also demonstrates excellent impact resistance, absorbing and dispersing heavy loads without cracking or shattering. This combination of toughness and durability ensures that machined parts like wear plates and rollers maintain their performance in the most demanding environments, delivering a significantly extended service life.
Machining & Customization
PU rods are supplied as semi-finished materials that are easily machined using standard CNC lathes, milling machines, and drilling equipment. They can be precision machined to exacting tolerances to produce complex components, including bushings, rollers, pulleys, and gears. Additionally, the material is available in a range of hardness levels (Shore A 60 to Shore D 80), allowing engineers to select the optimal grade for their specific application. We also provide customized colors (such as red, green, black, and natural) and custom diameters according to customer drawings.
Vibration Damping & Noise Reduction
Polyurethane offers exceptional vibration-damping properties due to its high hysteresis and internal friction. When utilized for anti-vibration mounts, pads, or isolators, PU efficiently absorbs and dissipates kinetic energy, effectively reducing noise and preventing harmful vibrations from spreading through structures. This makes it an ideal solution for machinery mounts, conveyor systems, and industrial equipment where noise control and component protection are critical. The ability to dampen vibrations also protects sensitive equipment from fatigue and structural damage over time.
Application Scope
This versatile polyurethane rod is extensively used for a wide range of industrial applications. In mechanical engineering, it is machined into bushings, sleeve bearings, rollers, and pinion gears for heavy machinery. In the mining and material handling sectors, it is utilized for conveyor rollers, scraper blades, and wear plates. It also serves as cushioning and sealing material in automotive and aerospace industries. PU rods are also used to manufacture custom tools, molds, and prototype parts. Its exceptional durability and versatility make it an ideal material solution for engineers.
