Are Plastic Multiflex Chains resistant to UV rays?

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.

Multiflex Chain


1. Lightweight

Plastic multiflex chains are lightweight, making them easy to handle and install in various applications. Their lightweight nature also reduces the overall weight and energy consumption of the conveyor system.

2. Flexibility

The modular design of plastic multiflex chains allows for flexibility in different directions, enabling them to adapt to the contours of the conveyor system. This flexibility ensures smooth and efficient movement of products or materials.

3. High Strength

Despite their lightweight construction, plastic multiflex chains are engineered to provide high strength and durability. They can withstand heavy loads and maintain their structural integrity even in demanding environments.

4. Low Maintenance

Plastic multiflex chains require minimal maintenance compared to traditional metal chains. They do not require lubrication, and their self-lubricating properties ensure smooth operation and reduce wear and tear.

5. Noise Reduction

Due to their plastic construction, multiflex chains produce less noise compared to metal chains, resulting in a quieter and more comfortable working environment.

6. Chemical Resistance

Plastic multiflex chains exhibit excellent resistance to various chemicals, acids, and alkalis. They are not affected by corrosion, making them suitable for applications in corrosive environments.

7. Cleanliness and Hygiene

Plastic multiflex chains are easy to clean and maintain, making them ideal for industries with strict cleanliness and hygiene requirements, such as food and pharmaceutical industries.

8. Energy Efficiency

The lightweight and flexible nature of plastic multiflex chains contribute to energy efficiency by reducing the power required to operate the conveyor system.

9. Versatility

Plastic multiflex chains can be customized to meet specific application requirements, such as different widths, lengths, and bending radii. They are compatible with various conveyor systems and can be used in a wide range of industries.

Multiflex Chain Application


1. Conveyor Systems

Plastic multiflex chains are commonly used in conveyor systems for industries such as automotive, packaging, and logistics. They ensure efficient movement of products along the production line.

2. Manufacturing and Assembly Lines

Plastic multiflex chains are ideal for manufacturing and assembly lines, where they facilitate the smooth flow of materials and components during the production process.

3. Distribution and Warehousing

In distribution and warehousing facilities, plastic multiflex chains enable the efficient sorting, handling, and storage of products, improving overall operational efficiency.

4. Packaging and Bottling

Plastic multiflex chains are used in packaging and bottling applications to transport products through various stages of the packaging process, ensuring timely and accurate packaging.

5. Material Sorting and Grading

For industries that require material sorting and grading, plastic multiflex chains provide a reliable and flexible solution for separating materials based on size, shape, or other criteria.

6. Cleanroom Environments

Plastic multiflex chains are suitable for use in cleanroom environments, where cleanliness and hygiene are critical. They prevent contamination and ensure the integrity of the production process.

Multiflex Chains Application

Working Principle

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

Consider the maximum load capacity required for the application to ensure the plastic multiflex chains can handle the weight of the products or materials being conveyed.

2. Application Environment

Evaluate the environmental conditions, such as temperature, humidity, and exposure to chemicals, to choose plastic multiflex chains that offer suitable resistance and durability.

3. Chain Material

Select the appropriate chain material, such as polyethylene (PE) or polypropylene (PP), based on the specific application requirements and the compatibility with the conveyed products or materials.

4. Chain Profile and Design

Consider the chain profile, including the width, pitch, and height, as well as the design features, such as side guards or cleats, to ensure optimal performance and product stability during the conveying process.

5. Environmental Factors

Take into account factors like dust, debris, or moisture that may be present in the environment and choose plastic multiflex chains that can withstand or resist these elements.

6. Conveyor System Layout

Analyze the conveyor system layout and determine the required chain length, configuration, and any specific requirements for curves, inclines, or declines.

7. Maintenance and Cleanability

Consider the ease of maintenance and cleanability of the plastic multiflex chains to ensure efficient operation and compliance with hygiene standards.

8. Cost Considerations

Evaluate the overall cost-effectiveness of the plastic multiflex chains, taking into account factors such as initial investment, maintenance requirements, and expected lifespan.

9. Supplier and Support

Choose a reputable supplier that offers quality plastic multiflex chains and provides excellent customer support, including technical assistance, spare parts availability, and after-sales service.
