What are the features of polyester rubber conveyor belts?

Polyester-rubber conveyor belts are widely used in industrial applications. These belts feature a multi-layer polyester structure, designated as EP (where "E" stands for polyester and "P" for polyester amide in the longitudinal direction). Scientific research has led to the development of high-strength, highly resilient, and exceptionally wear-resistant rubber materials. So, what exactly are the key features of these polyester-rubber conveyor belts?

1. Possesses excellent elasticity, impact resistance, tear resistance, and other properties, meeting the special application requirements even under complex conditions;

2. The polyester canvas conveyor belt exhibits minimal elongation under constant load, offering superior anti-slip performance compared to conventional belts and certain other common fabric-cored conveyor belts with higher elongation rates. This results in significantly reduced operational wear and tear during use, enabling more efficient, scientific, and streamlined operations—leading to lower overall equipment costs. Such advantages make it exceptionally well-suited for long-distance material transportation, effectively giving it a decisive edge over competing solutions.

3. Enhanced water resistance. When used in damp and cold environments, the rubber (and the belt's overall strength) remains unaffected—continuing to function reliably with a long service life.

4. Offers superior acid, alkali, temperature, and heat resistance; in the long run, using EP conveyor belts is more cost-effective.

5. The rubber conveyor belt is lightweight. Compared to other wide rubber belts used in the food industry, it features fewer layers, thinner construction, lighter weight, and greater flexibility during operation. This design helps boost production capacity, reduce equipment energy consumption, and optimize the transportation radius—meeting the demands for lower energy use (note: providing materials that facilitate natural energy conversion) and improved efficiency.

6. The covering layer has a tensile strength greater than 15 MPa, a load elongation exceeding 450%, and friction loss below 150 cubic meters.

7. The average length of the longitudinal test specimens for the strong interlayer adhesion strength (strength) must be greater than or equal to 4.5 N/mm, and the adhesion rate between the rubber surface and the fabric layer must exceed 4 N/mm.

8. Both the overall longitudinal tear strength and the full-thickness longitudinal reference elongation meet international standards. Aligning with global benchmarks, polyester-rubber conveyor belts have become the preferred choice for many customers as complementary components in their on-site machinery—and their popularity (indicating affection or respect) continues to grow steadily year after year. Conveyor belts are classified into standard and high-strength types based on the tensile strength of the fabric layers. High-strength canvas conveyor belts are further divided into nylon belts (NN belts) and polyester belts (EP belts).
