Choose the Right Fabric Belt—Built to Handle Your Workload, Environment, and Expectations
EP Rubber Conveyor Belt
- Excellent dimensional stability thanks to low elongation polyester warp yarns
- Custom widths ranging from 300mm to 3500mm are available, depending on the required thickness and roll length.
- Various cover grades allow EP belts to perform reliably in harsh environments — from -60℃ freezing conditions to 300℃ heat, and in contact with oily, flammable, or abrasive materials.
- Its low stretch properties deliver exceptional stability and operational consistency.
- Strong interlayer bonding and superior adhesion between cover and fabric layers enhance belt integrity.

EP Conveyor Belt Construction
- Top Rubber Cover: Protects the belt surface from wear, impact, and chemicals; customizable for heat, oil, or abrasion resistance.
- EP Fabric: Core layer made of polyester and nylon, offering high strength and low stretch for stable.
- Skim Rubber: Bonding layer between plies that enhances adhesion and impact resistance.
- Bottom Rubber Cover: Shields the underside from pulley wear and external abrasion.
- Rubber Moulded Edge: Seals the edges to prevent moisture and dust ingress, extending belt lifespan.
EP Conveyor Belt Tensile Strength Test
In this video, we put our Rubber Conveyor Belt to the test—literally.
To verify the tensile strength of the belt, we secure both ends of a prepared sample using a calibrated clamping fixture.
The testing machine gradually applies increasing force until the belt finally breaks.
At the moment of rupture, the computer records the peak load, giving us the precise tensile strength of the material.
This process ensures our conveyor belts meet the mechanical performance standards required for heavy-duty industrial applications.
NN Rubber Conveyor Belt
- Constructed with nylon-nylon fabric for high elasticity and flexibility.
- Runs smoothly on small pulleys without cracking or deformation.
- Excellent troughability for secure and stable material flow.
- Lightweight structure improves energy efficiency of the conveyor system.
- Strong impact absorption makes it ideal for drop loading conditions.

NN Conveyor Belt Construction
- Top Cover Rubber:
Protects the belt surface from abrasion, impact, weather, and harsh material contact. - NN Fabric:
Reinforced nylon in both warp and weft ensures flexibility, strength, and good load-bearing capacity. - Adhesive Glue:
Strong bonding layer that tightly connects rubber and fabric, preventing internal separation or delamination. - Bottom Cover Rubber:
Provides underside protection from rollers, pulleys, and wear caused by constant running contact.
NN Conveyor Belt Tensile Strength
This test demonstrates the tensile strength of our NN Conveyor Belt.
A standard sample is cut and placed into a calibrated tensile testing machine.
Both ends are clamped securely to ensure accurate results.
The machine applies steady pulling force until the belt breaks.
At the point of failure, the system records the maximum load the belt can withstand.
This value reflects the actual tensile strength of the material.
The process helps confirm that our NN Conveyor Belts meet the mechanical requirements for demanding industrial use.
