Plastic drag chains are widely used in industries, such as automotive, packaging, and food processing. However, it is important to ensure that these chains meet fire safety standards. In this article, we will explore the fire resistance ratings of plastic drag chains.

What Are Fire Resistance Ratings?

Fire resistance ratings are a measure of a material’s ability to withstand fire. These ratings are given after a material is subjected to standardized tests, such as the ASTM E84 test, which measures a material’s flame spread and smoke development. The higher the rating, the better the material’s ability to resist fire.

Fire Resistance Ratings of Plastic Drag Chains

Plastic drag chains are made of materials such as nylon, polypropylene, and polyethylene. These materials have varying fire resistance ratings.

  • Nylon drag chains have a Class 2 fire rating according to UL94 standards. This means that they are relatively difficult to ignite, and that when they do ignite, they self-extinguish within 30 seconds.
  • Polypropylene drag chains have a Class 1 fire rating according to UL94 standards. This means that they have the highest level of flame retardancy, and that they self-extinguish within 5 seconds.
  • Polyethylene drag chains have a Class 2 fire rating according to UL94 standards. They have similar characteristics to nylon drag chains.

Applications of Fire-Resistant Plastic Drag Chains

Fire-resistant plastic drag chains are used in a variety of applications where fire safety is a concern. For example, they are used in conveyors, where they help move products while minimizing the risk of fire. They are also used in automated equipment, such as robotic arms, where they help to protect against the risk of fire.
