Built to withstand flame, spark and surface fire hazards.
At Dexon Rubber, we supply premium FR Grade Rubber Conveyor Belts engineered for environments where fire exposure is a critical concern. These belts combine fire resistance and conductive safety, making them ideal for applications in coal, coke, grain, ore and other materials prone to ignition.
What is an FR Grade Conveyor Belt?
The term FR Grade stands for Fire-Resistant. Belts of this grade are specially constructed to meet both national and international standards for resistance to flame, while also ensuring static conductivity to reduce risk of electrostatic discharge. Their design accommodates surface applications where conveyed materials may be exposed to sparks or direct flame contact.
Key Features
- Fire-Resistant Covers: Designed with compounds and construction that comply with standards like IS-1891(FR), ISO-340(FR), DIN S/K, MSHA-FR, and CAN/CSA (FR).
- Static Conductivity: Ensures lower electrical resistance, reducing buildup of static charge during handling of combustible materials.
- Fabric Reinforcement Options: Available with carcass materials such as Nylon/Nylon (N/N) or EP (Polyester/Nylon) fabrics to match strength, flexibility and fire-safety requirements.
- High Tensile Strength & Elongation: For example, typical values include minimum tensile strength around 17 MPa and elongation ~350% (depending on standard) for belts rated under various norms.
- Heavy Duty Application Fit: Suited for environments with fire hazard exposure such as coal-handling, coke plants, grain elevators and other bulk material handling where fire risk is present.

Typical Applications
The FR Grade belt from Dexon Rubber works best in:
- Coal mines or coal-handling plants where bulk coal is exposed to spark, flame or heat.
- Coke ovens and adjacent conveyors where flammable gases or high temperatures exist.
- Grain elevators or flour mills where dust and bulk grain pose fire or explosion risk.
- Bulk handling systems conveying fire-prone materials like lignite, wood-chips or biomass.
- Any industrial conveyor system operating in an environment where fire resistance and static conductivity are mandated.
