Material Science Behind Plastic Drag Chains and Their Thermal Properties

Drag chains are used in numerous applications, such as machine tools, robots, and automated warehouses, to protect cables and hoses from wear and tear caused by repeated bending and flexing. Plastic drag chains are becoming increasingly popular due to their lightweight, corrosion-resistant, and self-lubricating properties. In this article, we will explore the material science behind plastic drag chains and their thermal properties.

What are Plastic Drag Chains?

Plastic drag chains are made from high-performance thermoplastics, such as polyamide (PA), polyoxymethylene (POM), and polypropylene (PP). These thermoplastics have excellent mechanical properties, such as high strength, stiffness, and toughness, which make them ideal for use in drag chains.

Thermal Properties of Plastic Drag Chains

Thermal properties of plastic drag chains are critical because they work in harsh environments that expose them to high temperatures and temperature fluctuations. The thermal properties of plastic drag chains include:

  • Melting Temperature: The temperature at which the thermoplastic melts and loses its shape.
  • Glass Transition Temperature: The temperature at which the thermoplastic transitions from a hard, glassy state to a rubbery, softer state.
  • Heat Distortion Temperature: The temperature at which the thermoplastic begins to lose its strength and stiffness due to thermal softening.
  • Coefficient of Thermal Expansion: The measure of how much the thermoplastic expands or contracts with temperature changes.

Application of Plastic Drag Chains

Plastic drag chains are used in various applications that require the protection of cables and hoses. The applications include:

  • Machine Tools
  • Robotics
  • Automated Warehouses
  • Medical Equipment
  • Food Processing
