Polyurethane Rubber Cord

Polyurethane (PU) rubber cord is a synthetic elastomer known for its exceptional durability, abrasion resistance, and mechanical properties. Here are some key features and common applications:

  1. Abrasion Resistance: Polyurethane rubber cord is highly resistant to abrasion, making it ideal for applications where the sealing material may be subjected to constant wear and friction. It maintains its integrity and sealing properties even in harsh operating environments.

  2. Tear Resistance: PU rubber cord exhibits excellent tear resistance, allowing it to withstand tearing and cutting forces without failure. This makes it suitable for applications where the sealing material may be subjected to mechanical stress or puncture risks.

  3. Flexibility and Elasticity: Polyurethane rubber cord is flexible and elastic, allowing it to conform to irregular shapes and surfaces for effective sealing. It provides a reliable seal even in applications with varying pressures and movements.

  4. Chemical Resistance: PU rubber cord offers good resistance to many chemicals, oils, greases, and solvents. While not as chemically resistant as some other elastomers like FKM Viton, it still performs well in a wide range of industrial environments.

  5. Weather Resistance: Polyurethane rubber cord exhibits good resistance to weathering, ozone, and UV radiation, making it suitable for outdoor applications where exposure to sunlight and environmental elements is expected.

  6. High Load-Bearing Capacity: PU rubber cord has a high load-bearing capacity, allowing it to withstand heavy loads and pressures without significant deformation. This property makes it suitable for applications requiring strong, durable seals.

  7. Noise and Vibration Dampening: Due to its resilient and cushioning properties, polyurethane rubber cord is often used for noise and vibration dampening applications, such as in machinery mounts, shock mounts, and equipment pads.

  8. Sealing Performance: PU rubber cord provides effective sealing performance in various applications, including hydraulic systems, pneumatic systems, automotive seals, and industrial equipment.

Polyurethane rubber cord is available in various diameters, hardness levels (durometer), and colors to suit different sealing requirements and application specifications. It can be easily cut, molded, or formed to create custom seals and gaskets for specific industrial or commercial applications.
