Flame resistant and fire resistant are terms often used interchangeably but they have distinct meanings. Flame resistant refers to materials that can withstand ignition and prevent the spread of flames. These materials are designed to self-extinguish once the flame source is removed, thus reducing the risk of fire spreading. Fire resistant, on the other hand, refers to materials that can withstand exposure to fire for a certain period without losing their structural integrity. Fire resistant materials can endure higher temperatures and longer exposure times compared to flame resistant materials. In the context of conveyor belts, flame resistant belts are used to prevent fire initiation, while fire resistant belts are designed to maintain functionality during a fire.
