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 preventing spontaneous combustion.
-
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 the 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, and improving them to a certain extent has no effect. However, using them together can greatly improve the flame retardant effect.
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:
🧵
Dense Core Structure
A dense core woven from warp and weft filaments and covered cotton, providing exceptional structural integrity.
🔗
High Bonding Strength
Immersing with specially formulated PVC material achieves extremely high bonding strength between the core and the cover adhesive.
🛡️
Specially Formulated Cover Adhesive
Specially formulated cover adhesive makes the belt resistant to impact, tear, and wear for extended service life.
⚙️

Frequently Asked Questions (FAQ)
Q
What makes a conveyor belt flame retardant?
Flame retardant conveyor belts are made using specially formulated compounds that incorporate flame retardants. These retardants work through mechanisms such as inhibiting oxidation reactions, releasing endothermic compounds, forming protective covering layers, and diluting combustible gases — all of which prevent or suppress ignition and combustion.
Q
What certifications do flame retardant conveyor belts need to pass?
Flame retardant conveyor belts must pass flame retardant testing and electrostatic testing to obtain a certificate of conformity. In mining and coal industry applications, a coal safety mark is also required to ensure compliance with safety standards.
Q
What material is used as the skeleton of the flame retardant conveyor belt?
The product uses an integral core as the skeleton material. The core is a dense structure woven from warp and weft filaments and covered cotton. It is then impregnated and coated with specially formulated PVC material to achieve excellent anti-static and flame retardant properties.
Q
How does the synergistic effect of flame retardants improve performance?
Individual flame retardants may have limited or no significant effect when used alone. However, combining multiple types of flame retardants creates a synergistic effect, where the combined action greatly enhances the overall flame retardant performance — far beyond what each component could achieve independently.
Q
What are the key mechanical properties of flame retardant conveyor belts?
Flame retardant conveyor belts are designed to be resistant to impact, tearing, and wear. The combination of a high-bonding-strength core, specially formulated cover adhesive, and PVC coating ensures excellent mechanical durability, providing users with the longest possible service life and cost-effective installation.
Q
Can the flame retardant conveyor belt formula be customized for specific working conditions?
Yes. The design of the rubber conveyor belt formula must be adjusted according to on-site working conditions. Different industrial environments may require different levels of flame retardancy, heat resistance, and anti-static performance, and the formulation can be tailored to meet those specific operational requirements.
