Flame Resistant Conveyor Belt
Product Features:
For mining, wood, paper & pulp, sugar & food, recycling and chemical & fertilizer plants.In some environments where coal dust, gas, fertilizer or other combustible materials are involved,it is essential that the conveyor belts being used cannot create static electricity that can ignite gases and dust in the atmosphere.
