Product Introduction
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:
-
1
Inhibitory Effect: Suppresses the occurrence of oxidation reactions, achieving the effect of spontaneous combustion prevention.
-
2
Endothermic Reaction: Compound releases crystalline water or dehydrates when heated, suppressing temperature rise.
-
3
Covering Effect: Stable covering layer or foam material is generated under high temperature, playing the role of heat insulation and air isolation.
-
4
Dilution Effect: Generates a large amount of non-combustible gas when heated, diluting combustible gas to a non-combustible concentration range.
-
5
Transfer Effect: Changes the mode of thermal decomposition of polymer materials and suppresses the generation of combustible gases.
-
6
Synergistic Effect: 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. Improving them individually to a certain extent has limited effect. However, using them together can greatly improve the overall flame retardant performance.

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
Q
What makes a flame retardant conveyor belt different from a standard conveyor belt?
Flame retardant conveyor belts are specifically designed with special PVC materials and flame retardant compounds that suppress combustion, reduce heat buildup, and prevent the spread of fire. Standard conveyor belts lack these protective properties and are not suitable for high-risk environments such as coal mines or tunnels.
Q
What certifications do flame retardant conveyor belts need to meet?
Flame retardant conveyor belts must pass flame retardant testing and electrostatic testing. They are required to obtain a certificate of conformity and a coal safety mark before being used in underground coal mining or other fire-sensitive applications.
Q
How does the synergistic combination of flame retardants work?
Individual flame retardants may show limited effectiveness on their own. However, when multiple types are combined — such as inhibitory, endothermic, and covering compounds — they work together synergistically to significantly enhance the overall flame retardant performance of the conveyor belt.
Q
What type of core material is used in this flame retardant conveyor belt?
This conveyor belt uses an integral core as the skeleton material. The core is densely woven from warp and weft filaments and covered cotton, then impregnated with a specially formulated PVC compound to achieve extremely high bonding strength and maximum durability.
Q
Is the flame retardant conveyor belt suitable for anti-static applications?
Yes. The PVC coating material used in this product has excellent anti-static properties in addition to its flame retardant performance. This makes it suitable for environments where both fire prevention and static discharge control are critical, such as underground coal mines.
Q
How long is the service life of a flame retardant conveyor belt?
The service life depends on several factors including the quality of the woven core, the bonding strength between the core and cover adhesive, and the formulation of the cover rubber. With proper installation and use, these belts are engineered to provide the maximum service life while remaining economical to operate and maintain.
