In industrial production, conveyor belts are indispensable and important equipment, and the choice of materials directly determines its performance and scope of application. Today, we will deeply analyze three common conveyor belt materials-polyethylene (PE), polyvinyl chloride (PVC) and polyurethane (PU), and see their respective advantages and disadvantages, and how to choose the most suitable material according to needs!

. Polyethylene (PE): Lightweight and non-toxic, a good helper in the food industry

Features: lightweight, non-toxic, chemical corrosion resistant, low temperature resistant, and easy to process. Applications: food packaging, plastic bags, water pipes, conveyor belts, etc.

Advantages: 1. Meet food grade standards, hygienic and safe, suitable for direct contact with food. 2. Chemical corrosion resistant, suitable for a variety of light industrial environments. Disadvantages: 1. Poor wear resistance, low strength, not suitable for high-load scenarios. 2. Poor high temperature resistance, easy to deform under long-term high temperature environment.

2. Polyvinyl chloride (PVC): high hardness, low cost, all-rounder in the industrial field

Features: high hardness, wear resistance, chemical corrosion resistance, and good flame retardancy. Applications: building materials (such as pipes, floors), wire insulation, medical equipment, etc.

Advantages: 1. Low cost and economical. 2. Strong durability, suitable for a variety of industrial environments. Disadvantages: 1. May contain plasticizers and is not suitable for direct contact with food. 2. Easy to become brittle in low temperature environments and poor flexibility.

3. Polyurethane (PU): High elasticity, wear resistance, the first choice for complex environments

Polyurethane (PU) is divided into polyester PU and polyether PU according to different raw materials, and the performance of the two has different focuses

Polyester PU Features: good oil resistance, strong tear resistance, and excellent wear resistance.

Advantages: 1. Suitable for high-load and high-wear environments. 2. Outstanding oil resistance, suitable for scenes with more oil. Disadvantages: 1. Poor hydrolysis resistance. 2. Easy to age in humid environments.

Polyether PU Features: Good hydrolysis resistance, excellent elasticity, and good low-temperature performance.

Advantages: 1. Suitable for humid or water-contact environments. 2. Still maintain good elasticity in low temperature environments. Disadvantages: 1. Poor oil resistance 2. Not suitable for scenes with more oil.

How to choose the right conveyor belt material?

Food industry: PE or polyether PU is preferred because they meet food grade standards and are safe and hygienic.

High strength and wear-resistant environment: Choose polyester PU, which has excellent wear resistance and oil resistance. Suitable for machinery manufacturing, automotive industry, food processing, cold chain logistics

Low cost and flame retardant requirements: Choose PVC, which is economical and durable. Suitable for the construction industry and industrial equipment.
