Flame-Retardant Cover Rubber
Flame-retardant cover rubber grades are designed for conveyor belt applications operating in environments where fire hazards may be present. These specialised rubber compounds help limit flame propagation and reduce the risk of fire spreading along the conveyor system, supporting safer operation in demanding industrial settings.
Manufactured to comply with recognised safety standards, fire-retardant grades maintain durability and mechanical stability under harsh operating conditions. They are commonly used in industries such as mining, cement, power generation, and bulk material handling.
Fire Retardance Ratings
Values shown are typical reference data only. Properties and heat classifications are generally in accordance with recognised conveyor belt standards such as DIN 22102, ISO 14890, and related international test methods. Actual performance may vary depending on operating conditions and compound formulation.
Grade / Designation | Operating Environment | Primary Safety Focus | Min. Tensile Strength (MPa) | Max. Abrasion Loss (mm³) | Min. Elongation at Break (%) | Common Applications |
|---|---|---|---|---|---|---|
DIN-K | Above Ground | Self-extinguishing with covers intact | 15 | 200 | 350 | Surface coal handling, grain silos, biomass power plants, enclosed surface galleries |
DIN-S | Underground / Confined | Self-extinguishing with OR without covers | 14 | 250 | 300 | Underground coal mining, highly enclosed tunneling projects, explosive dust environments |
