Oil-resistant conveyor belt

Product Description

Application

Oil-resistant conveyor belts are used for transporting oils, including mineral oil, vegetable oil, animal oil, organic solvents, and other oily materials in food processing plants or chemical factories.

Features

This product is meticulously crafted from a blend of all-cotton canvas, viscose cotton, polyester-cotton, nylon, and interwoven, impregnated canvas, processed through advanced techniques such as calendering, adhesive application, cutting, and heat vulcanization. The cover rubber is made from specialized oil-resistant compounds tailored to meet varying oil-resistance requirements, then applied to the belt surface using a unique manufacturing process to safeguard the core material from damage.

Technical data

After the aging test (70°C × 168 hours), the changes in tensile strength coverage for "tensile strength at break" and "elongation at break" did not exceed 25%.

Level	Tensile Strength (MPa)	Elongation at Break (%)	Wear and tear (mm³)
L	≥14.0	≥350	≤200
D	≥16.0	≥350	≤160
Note: L – under standard oil-resistant conditions; D – under high-wear and oil-resistant conditions.

Options

Meets MOR (Medium Oil Resistance) or OR (Oil Resistance) standards
1. The MOR conveyor belt only requires a specific oil-resistant grade.
2. Use OR conveyor belts in applications requiring a high level of oil resistance.

Oil-Resistant Technical Data

Type	Operating temperature	The right type of oil	Expandability (72 hours)
MOR	-30°C to 70°C	Mineral oil, organic solvents	Expandability ≤20%
OR	-30°C to 70°C	Vegetable oil, animal fat	Expandability ≤5%
