Flame Resistant Conveyor Belt

Unlike ordinary rubber conveyor belts that may ignite easily and allow flames to spread along the conveying route, YUFENG Flame Resistant Conveyor Belt provides integrated fire safety protection through flame suppression technology, static control design and reinforced belt construction.

YUFENG products have been successfully applied in more than 32 countries across mining, chemical, energy and heavy industries. Every belt is tested before shipment according to international safety requirements, including MT 914, ISO 340, EN 12882, SGS and BV verification standards.

Why Industrial Buyers Choose Flame Resistant Belt?

1. Conveyor Fire Risk Comes From More Than Ignition

In high-risk industries, conveyor belts operate continuously near combustible materials such as coal dust, chemical products and flammable industrial materials. Once a conventional rubber belt catches fire, flames can quickly spread along the belt surface, creating serious risks to equipment, production continuity and personnel safety.

For this reason, purchasing decisions should not focus only on whether a belt can resist ignition. A reliable flame-resistant conveyor belt must also control flame propagation, reduce smoke generation, prevent static discharge and maintain structural strength during fire exposure. YUFENG focuses on complete fire safety performance rather than adding simple flame retardants into rubber materials.

YUFENG Fire Safety Technology System

1. Multi-Stage Flame Retardant Rubber System

The cover rubber of YUFENG Flame Resistant Belt uses chloroprene rubber (CR) as the base material combined with a multi-stage flame retardant system.

The gas-phase flame retardant component captures free radicals during combustion and interrupts the combustion chain reaction. The condensed-phase system forms a protective carbon layer when heated, reducing oxygen contact and heat transfer.

The formula also integrates smoke suppression additives, reducing smoke generation by approximately 40% compared with ordinary flame-resistant belts. A halogen-free flame retardant option is available for applications requiring lower smoke toxicity.

Key flame protection performance:

2. Anti-Static Conductive Network Protection

Static electricity is an important safety concern in underground mining, chemical plants and combustible dust environments.

During operation, friction between the conveyor belt and transported materials may generate static charges. Without effective conductivity, accumulated static electricity can create sparks capable of igniting flammable gases, dust or vapors.

YUFENG integrates conductive carbon black networks throughout the rubber compound to maintain stable electrical conductivity.

Anti-static performance data:

The conductive structure helps prevent static accumulation throughout the service life of the belt.

3. Fire-Resistant Reinforced Carcass Structure

During a fire incident, maintaining belt integrity is essential for preventing conveyor system failure. YUFENG uses high-strength EP canvas with fire-resistant impregnation treatment to improve structural stability under flame exposure.

The reinforced carcass provides:

This design helps reduce risks of belt separation and sudden conveyor shutdown during emergency conditions.

Safety Grade Classification

YUFENG provides different flame-resistant conveyor belt safety grades according to industry risks, operating conditions and applicable regulatory requirements. Customers can select the appropriate belt grade based on fire exposure, static electricity risk, conveying materials and installation environment.

For special working environments, YUFENG can provide customized compound combinations such as flame + heat resistance, flame + oil resistance and flame + abrasion resistance.

1. Available Customization Options

Fire Performance Test Results and Certification Data

YUFENG Flame Resistant Belts undergo factory safety testing covering flame behavior, combustion control, surface resistance and mechanical performance. Testing can be arranged according to the applicable product grade and customer requirements.

2. Alcohol Burner Test

YUFENG Mining-grade Flame Resistant Conveyor Belt can be evaluated using alcohol burner testing according to applicable GB/T 3685 and MT 113 requirements. The referenced test uses a 95% ethanol burner with a 60 mm flame height and a 30-second exposure period.

These results indicate rapid flame extinction and controlled combustion behavior under the stated test conditions.

3. Propane Burner Test

The propane combustion test evaluates flame propagation control under a more severe fire exposure condition and can be performed according to ISO 340 and applicable EN 12882 requirements.

Safety Comparison

For safety-critical conveying systems, buyers need to evaluate more than basic flame resistance. Flame propagation, static control, smoke generation and mechanical strength under fire exposure are also important factors when selecting a conveyor belt.
