Impact resistance of plastic chains in industrial applications

Impact Resistance of Plastic Chains in Industrial Applications

In industrial applications, chains are essential components that connect various machines and equipment. They provide a reliable way to transfer power, motion, and materials from one point to another. However, not all chains are created equal, and some are better suited for certain environments and demands. One type of chain that has gained popularity in recent years is plastic chains. Plastic chains offer several benefits over traditional metal chains, such as lightweight, corrosion resistance, and low noise. But one critical factor that determines their performance in industrial applications is their impact resistance. In this blog post, we will explore the impact resistance of plastic chains and their suitability for different industrial applications.

Definition of Impact Resistance

Impact resistance refers to the ability of a material to withstand sudden blows or shock without breaking or deforming. In the context of chains, impact resistance is crucial because chains often encounter sudden impacts or vibrations during operation. For example, a conveyor chain may hit a hard object or experience a sudden change in load, causing stress on the chain links. If the chain cannot withstand the impact, it may break or deform, leading to downtime, equipment damage, and safety hazards.

Factors Affecting Impact Resistance of Plastic Chains

Several factors affect the impact resistance of plastic chains, including:

  • Material composition: Different types of plastic materials have varying impact resistance properties. For example, acetal copolymer has higher impact resistance than nylon.
  • Chain design: The shape, size, and thickness of the chain links can affect their impact resistance. A thicker and wider link can withstand more impact than a thinner and narrower one.
  • Environment: The temperature, humidity, and chemical exposure of the application environment can affect the impact resistance of plastic chains. For example, exposure to high temperatures can cause the chain links to soften and become more susceptible to impact damage.

Benefits of Plastic Chains’ Impact Resistance

The impact resistance of plastic chains offers several benefits in industrial applications, including:

  • Reduced downtime: Since plastic chains can withstand impact better than metal chains, they are less likely to break or deform during operation, resulting in less downtime and maintenance costs.
  • Improved safety: Plastic chains’ impact resistance reduces the risk of sudden chain failure, which can cause injuries and accidents to workers and damage to equipment.
  • Increased productivity: With less downtime and maintenance, plastic chains can improve the overall productivity of the industrial process.

Applications of Plastic Chains with High Impact Resistance

Plastic chains with high impact resistance are suitable for various industrial applications that involve sudden impacts or vibrations. Some of these applications include:

  • Conveyor systems: Plastic chains are ideal for conveyor systems that transport fragile or delicate items, such as bottles, cans, and electronics. The impact resistance of plastic chains ensures the safe and smooth transfer of these items without damage.
  • Food processing: Plastic chains are widely used in the food processing industry because they are corrosion-resistant, easy to clean, and do not contaminate the food. The impact resistance of plastic chains also ensures the safe and hygienic transport of food items.
  • Agriculture: Plastic chains are suitable for agricultural applications because they are resistant to chemicals, fertilizers, and ultraviolet (UV) light. The impact resistance of plastic chains ensures the reliable operation of agricultural machinery and equipment.


Q: Can plastic chains replace metal chains in all industrial applications?

A: No, plastic chains cannot replace metal chains in all industrial applications. Plastic chains have their unique properties and limitations, and it is essential to choose the right type of chain for each application based on its demands and requirements.

Q: Are plastic chains more expensive than metal chains?

A: The cost of plastic chains varies depending on the material composition, design, and application requirements. In some cases, plastic chains may be more expensive than metal chains, while in other cases, they may be more affordable.

Q: Can plastic chains withstand high temperatures?

A: The impact resistance of plastic chains decreases at high temperatures, and they may soften or melt if exposed to extreme heat. However, some plastic materials, such as polyphenylene oxide (PPO), can withstand high temperatures up to 150¡ãC.

Q: Do plastic chains require special maintenance?

A: Plastic chains require less maintenance than metal chains because they do not rust, corrode, or require lubrication. However, it is essential to inspect them regularly for wear and tear, especially in high-impact applications.
