The comparison above is a general guideline. Actual performance depends on belt construction, reinforcement, thickness, surface design, and operating conditions. Material selection should always match the complete conveyor application rather than the material name alone.

The correct selection process should begin with the actual operating conditions.

1. Consider the Conveyed Material

The transported product is one of the most important selection factors.

Evaluate:

Examples:
Light packages usually work well with PVC.
Oily or hygiene‑sensitive products often require PU.
Heavy abrasive materials generally require rubber.

2. Check Load and Conveyor Capacity

The load determines the required belt strength and construction.

Using a light‑duty belt for heavy materials is one of the most common causes of premature failure.

3. Evaluate Working Environment

The operating environment can significantly affect belt performance.

Consider:

A belt suitable for one environment may fail quickly in another if the material compatibility is incorrect.

4. Consider Hygiene Requirements

For food processing, pharmaceutical, and clean applications, hygiene requirements must be considered.

Important factors include:

PU and suitable PVC grades are commonly selected for hygiene‑sensitive applications.

Material Selection Priority

When choosing between PVC, PU, and rubber, follow this order:

The lowest initial cost does not always provide the lowest long‑term cost.

Material is only one part of the conveyor belt specification.

A suitable belt material can still fail if the conveyor design is not matched correctly.

Replacing a failed belt with the same material does not always solve the problem.

First identify the failure cause.

Understanding the failure reason helps prevent repeated replacement with an unsuitable belt.

This guide provides a starting point. The final specification should always consider the complete operating environment.

Choosing Only by Price

A cheaper belt may increase maintenance costs if replacement frequency is high.

Replacing the Old Belt Without Finding the Failure Cause

The previous belt may not have matched the actual application.

Using Light‑Duty Belts for Heavy Materials

Heavy loads require stronger belt construction.

Ignoring Conveyor Design

Speed, tension, pulley size, and loading conditions also affect belt performance.

Providing complete application information helps determine the correct belt specification.

The more complete the operating information, the more accurately the belt material and construction can be selected.

Is PU better than PVC conveyor belt?

Not always. PU is usually preferred for hygiene, oil resistance, and higher wear requirements. PVC may be more economical for general conveying applications.

Is rubber better than PVC for heavy‑duty applications?

Generally, rubber is more suitable for heavy‑duty applications because of its abrasion and impact resistance.

Which conveyor belt material is best for food processing?

PU and suitable PVC grades are commonly used for food‑related applications. The correct choice depends on cleaning requirements and operating conditions.

Which material is best for abrasive materials?

Rubber is generally preferred for abrasive bulk materials such as stone, aggregate, and mining products.

What information is needed before selecting a conveyor belt?

You should provide the conveyed material, capacity, belt size, speed, temperature, environment, and application requirements.
