Product Selection Differences for Polyurethane (PU) Joints

When selecting Polyurethane (PU) joints, there are several key differences to consider among the available options:

1. Hardness: PU joints are available in different hardness levels, typically measured on the Shore A scale. Softer PU joints (lower Shore A value) provide better flexibility and vibration absorption, while harder PU joints (higher Shore A value) offer greater durability and load-bearing capacity.

2. Abrasion Resistance: Consider the abrasion resistance of the PU joint, especially if it will be exposed to high wear and tear environments. PU joints with high abrasion resistance will have a longer service life.

3. Chemical Resistance: Depending on the application, you may need PU joints with specific chemical resistance properties to withstand exposure to certain substances like oils, solvents, or chemicals without degrading.

4. Compression Set: This refers to the ability of the PU joint to recover its original shape after being compressed. Lower compression set values indicate better recovery properties, making the joint more resilient over time.

5. Temperature Resistance: Ensure that the PU joint can withstand the temperature conditions it will be exposed to. Some PU joints are designed to perform well in a wide range of temperatures, making them suitable for various applications.

6. Load-Bearing Capacity: Consider the maximum load that the PU joint can bear without failing. Ensure that the selected PU joint can handle the specific loads expected in your application.

7. Flexibility: The flexibility of the PU joint is crucial, especially in applications where movement or vibration absorption is required. Flexible PU joints can accommodate dynamic movements without compromising performance.

By evaluating these key factors, you can select the most suitable PU joint based on the specific requirements of your application.
