Are Plastic Multiflex Chains resistant to environmental elements?

In the realm of material handling and power transmission, plastic multiflex chains have emerged as a versatile and effective solution for conveying a wide range of products and materials. These chains, constructed from durable thermoplastic materials such as polyethylene (PE) or polypropylene (PP), offer a compelling combination of flexibility, strength, and low maintenance, making them well-suited for diverse applications.

Advantages of Plastic Multiflex Chains

1. Lightweight

Plastic multiflex chains are significantly lighter than traditional metal chains, reducing the overall weight of the conveying system. This not only enhances energy efficiency but also makes installation and maintenance easier.

2. Flexibility

Plastic multiflex chains offer exceptional flexibility, allowing them to navigate complex conveyor layouts and adapt to changing production needs. Their modular design enables smooth articulation in multiple directions, facilitating efficient material transfer.

3. High Strength

Despite their lightweight nature, plastic multiflex chains boast impressive strength and load-bearing capacity. They can withstand heavy loads and provide reliable performance in demanding applications.

4. Low Maintenance

Plastic multiflex chains require minimal maintenance compared to traditional metal chains. They are resistant to corrosion, rust, and wear, reducing the need for frequent lubrication and replacement.

5. Noise Reduction

Due to their plastic composition, multiflex chains generate less noise during operation, creating a quieter and more comfortable working environment.

6. Chemical Resistance

Plastic multiflex chains exhibit excellent resistance to chemicals, oils, and other substances, ensuring long-lasting performance even in corrosive or harsh environments.

7. Cleanliness and Hygiene

Plastic multiflex chains are easy to clean and maintain sanitary conditions. They are non-porous, preventing the accumulation of dirt, debris, and bacteria, making them ideal for applications requiring high cleanliness standards.

8. Energy Efficiency

As lightweight and flexible chains, plastic multiflex chains contribute to improved energy efficiency in material handling systems. They require less power to operate, resulting in energy savings.

9. Versatility

Plastic multiflex chains can be customized and adapted to suit a wide range of applications and conveyor systems. Their modular design allows for easy assembly, modification, and integration with existing systems.

Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are commonly used in conveyor systems to transport various products and materials in industries such as food processing, packaging, and automotive.

2. Manufacturing and Assembly Lines

In manufacturing and assembly lines, plastic multiflex chains facilitate the movement and transfer of components, ensuring efficient production processes.

3. Distribution and Warehousing

Plastic multiflex chains are employed in distribution and warehousing operations to handle and sort packages, enhancing logistics efficiency.

4. Packaging and Bottling

Plastic multiflex chains play a crucial role in the packaging and bottling industry, enabling the smooth flow of products during filling, capping, and labeling processes.

5. Material Sorting and Grading

Plastic multiflex chains are utilized in material sorting and grading systems, accurately directing products based on size, weight, or other characteristics.

6. Cleanroom Environments

Plastic multiflex chains are suitable for cleanroom environments that require strict cleanliness standards, as they can be easily cleaned and do not contribute to particle contamination.

Working Principle of Plastic Multiflex Chains

Plastic Multiflex Chains operate on the principle of interlocking modular units. The chain consists of individual plastic links or modules that are interconnected to form a continuous chain loop. Each module has built-in tabs or hinges that allow it to flex and articulate, providing flexibility in various directions.

The chain is driven by sprockets or sprocket wheels, which engage with the tabs on the modules and propel the chain forward. The modular design allows for easy assembly, disassembly, and customization of the chain to suit specific conveyor layouts and requirements.

As the sprockets rotate, they engage with the modules, causing them to articulate and move along the conveyor path. The interlocking design ensures smooth and synchronized movement of the chain, allowing for the efficient transfer of products or materials from one point to another.

How to Select the Right Plastic Multiflex Chains

1. Load Capacity

Determine the maximum load capacity required for your application to ensure the chosen plastic multiflex chain can handle the weight effectively.

2. Application Environment

Consider the environmental conditions the chain will be exposed to, such as temperature variations, moisture, chemicals, or abrasive substances, and choose a chain with appropriate resistance properties.

3. Chain Material

Select the suitable plastic material for the chain based on factors such as chemical compatibility, wear resistance, and durability. Polyethylene (PE) and polypropylene (PP) are commonly used materials.

4. Chain Profile and Design

Choose the right profile and design of the plastic multiflex chain to match the specific requirements of your conveyor system, including width, pitch, and configuration.

5. Environmental Factors

Consider factors like temperature fluctuations, exposure to UV radiation, moisture, or corrosive substances, and select a chain with appropriate resistance properties.

6. Conveyor System Layout

Take into account the layout and configuration of your conveyor system to ensure compatibility and proper integration of the plastic multiflex chain.

7. Maintenance and Cleanability

Evaluate the ease of maintenance and cleanability of the chain, considering factors such as access for cleaning, resistance to dirt buildup, and compatibility with cleaning agents.

8. Cost Considerations

Consider the overall cost-effectiveness of the plastic multiflex chain, including its initial cost, maintenance requirements, and expected lifespan.

9. Supplier and Support

Choose a reputable supplier who can provide technical support, customization options, and reliable after-sales service.

Installation and Maintenance of Plastic Multiflex Chains


1. Preparatory Steps

Prior to installation, ensure that the conveyor system and supporting structure are properly prepared and aligned.

2. Chain Assembly

Assemble the plastic multiflex chain by interconnecting the modular units, ensuring that the chain is properly tensioned and aligned.

3. Sprocket Installation

Install the sprockets or sprocket wheels onto the drive and idle shafts, ensuring proper alignment and engagement with the chain.

4. Tracking Adjustment

Adjust the tracking of the chain by aligning the sprockets and modifying the position of the chain within the conveyor system to ensure smooth and precise movement.


1. Regular Cleaning

Regularly clean the plastic multiflex chain to remove dirt, debris, and contaminants that may affect its performance.

2. Inspection

Periodically inspect the chain for any signs of wear, damage, or misalignment. Replace any worn or damaged modules or components promptly.

3. Lubrication

Apply a suitable lubricant to the chain, ensuring it is evenly distributed and does not attract dirt or contaminants.

4. Repair and Replacement

If any modules or components are damaged or worn beyond repair, replace them with new ones to maintain the chain’s performance and integrity.
