The flame retardant performance of conveyor belts: Currently, the main formula used by conveyor belt manufacturers is flame retardants, and the selection of flame retardants mainly focuses on the following categories:
1Inhibitory Effect: Suppresses the occurrence of oxidation reactions, achieving the effect of spontaneous combustion prevention.
2Endothermic Reaction: The compound releases crystalline water or dehydrates when heated, suppressing temperature rise.
3Covering Effect: A stable covering layer or foam material is generated under high temperature, playing the role of heat insulation and air isolation.
4Dilution Effect: Generates a large amount of non-combustible gas when heated, diluting the combustible gas to a non-combustible concentration range.
5Transfer Effect: Changes the mode of thermal decomposition of polymer materials and suppresses the generation of combustible gases.
6Synergistic Combination: The combination of synergistic flame retardants has little or no significant effect when used alone.
💡
From the above, it can be seen that flame retardants have a certain cooling effect on high temperature resistance, and improving them to a certain extent has no effect. However, using them together can greatly improve the flame retardant effect.
The Function of Flame Retardants

Cooling SuppressionAchieves high temperature resistance of the rubber conveyor belt to the ignition level. The rubber conveyor belt formula must be adjusted according to on-site working conditions. The conveyor belt has passed flame retardant testing and electrostatic testing, and has obtained a certificate of conformity, coal safety mark, and customer recognition.
Product Features
This product uses integral core as the skeleton material, and is made by impregnating and coating PVC material with excellent anti-static, flame retardant and other properties, and then plasticizing it.
The maximum service life of the belt body is determined by the following factors:
✓(1) A dense core woven from warp and weft filaments and covered cotton.
✓(2) Immersing with specially formulated PVC material achieves extremely high bonding strength between the core and the cover adhesive.
✓(3) Specially formulated cover adhesive — making the belt resistant to impact, tear, and wear.
⚙️
Mechanical Properties: Flame retardant conveyor belts have excellent mechanical properties and can provide users with the longest service life and economical installation and use.
Frequently Asked Questions (FAQ)
Q
What is a flame retardant conveyor belt and how does it work?
A flame retardant conveyor belt is a type of conveyor belt designed to resist ignition and slow the spread of fire. It works through a combination of mechanisms including inhibiting oxidation reactions, endothermic cooling, forming protective covering layers, diluting combustible gases, and altering the thermal decomposition of polymer materials. The combination of multiple synergistic flame retardants greatly enhances the overall flame retardant effect.
Q
What materials are used in the construction of flame retardant conveyor belts?
Flame retardant conveyor belts are typically made using an integral core skeleton material. The core consists of a dense weave of warp and weft filaments covered with cotton. The core is then impregnated with a specially formulated PVC material that provides anti-static and flame retardant properties, followed by a specially formulated cover adhesive. The entire belt is then plasticized to achieve its final properties.
Q
What certifications should a flame retardant conveyor belt have?
A qualified flame retardant conveyor belt should have passed both flame retardant testing and electrostatic testing. It should carry a certificate of conformity and, where applicable for mining use, a coal safety mark. These certifications ensure the product meets industry safety standards and has been validated for use in hazardous environments.
Q
What are the key mechanical properties of a flame retardant conveyor belt?
Flame retardant conveyor belts are engineered for excellent mechanical performance, including high resistance to impact, tearing, and surface wear. The high bonding strength between the core and cover adhesive ensures long-term structural integrity. These properties combined provide users with maximum service life and cost-effective installation and operation.
Q
How do flame retardants contribute to cooling and temperature control in conveyor belts?
Flame retardants contribute to temperature control through endothermic reactions — releasing crystalline water or dehydrating when heated — which absorbs heat energy and suppresses temperature rise. Additionally, the cooling suppression effect helps keep the conveyor belt below the ignition threshold, providing reliable protection in high-temperature operating conditions.
Q
Can the flame retardant conveyor belt formula be customized for specific working conditions?
Yes. The rubber conveyor belt formula must be adjusted according to specific on-site working conditions. Different industrial environments — such as mining, chemical plants, or heavy manufacturing — may require varying levels of flame retardancy, anti-static performance, and mechanical durability. Manufacturers can tailor the PVC formulation and cover adhesive composition to meet the precise demands of the application.
