In the industrial conveying sector, the selection of oil-resistant conveyor belts, corrugated sidewall belts, and heat-resistant belts directly impacts production efficiency and equipment longevity. This guide systematically analyses material properties, performance parameters, and supplier evaluation criteria to assist technical decision-makers, procurement managers, and project leaders in making informed purchasing decisions, ensuring long-term stable operation of conveying systems.

I. Core Materials and Performance Comparison of Oil-Resistant Conveyor Belts

Oil-resistant conveyor belts primarily utilise nitrile rubber (NBR), polyvinyl chloride (PVC), or polyurethane (PU) as the cover layer. Among these, NBR offers the superior oil resistance, capable of withstanding permeation from mineral oils, vegetable oils, and similar substances. It is suitable for applications such as food processing and mining machinery. Corrugated sidewall belts incorporate wavy sidewalls along the base belt to prevent material spillage, with sidewall heights ranging from 30mm to 240mm. Selection depends on the conveying angle (up to 90° maximum). For heat-resistant belts, the temperature rating of the cover rubber is critical:

Material Type    Temperature Range    Applications

EPDM Rubber    -30℃~150℃ High-temperature slag handling

Silicone rubber    -60℃~200℃    Chemical feedstock processing

II. Key Procurement Metrics and Industry Standards

Technical evaluators should prioritise the following parameters: tensile strength (ISO 283 standard), abrasion resistance (DIN 53516), and oil resistance rating (ASTM D1460). For oil-resistant belts, premium products should meet:

Volume expansion rate ≤25% (24-hour oil immersion test)

Elongation at break ≥400%

Interlayer adhesion strength ≥8 N/mm

Corrugated sidewall conveyor belts require additional assessment of sidewall tear resistance and lateral rigidity to prevent deformation from material impact.

III. Five Key Dimensions for Supplier Evaluation

Business decision-makers should conduct a comprehensive assessment based on:

- Production capacity (presence of vulcanisation production lines)

- Quality inspection systems (X-ray flaw detection equipment)

- Project experience (successful industry-specific implementations)

- After-sales response (48-hour on-site commitment)

- Environmental certifications (REACH/ROHS compliance)

Suppliers should be requested to provide:

- Third-party inspection reports (SGS/TÜV)

- Actual wear resistance test videos

IV. Common Misconceptions and Solutions

Frequent errors encountered by maintenance personnel include:

Misconception 1: Oil-resistant belts can substitute acid/alkali-resistant belts → Selection must be based on chemical compatibility charts

Misconception 2: Higher sidewall height is always better → Excessive height reduces belt rigidity; calculation based on conveying volume is recommended

Solution: Establish a material-belt compatibility database and conduct regular infrared thermal imaging inspections
