Flame Retardant or Fire Resistant Plastic Compounds
Flame Retardant (FR) plastics are essential to devices we use every day, providing a valuable tool in fire prevention. In order for fire to occur, three basic elements must exist: fuel, heat, and oxygen. The science of flame retardance uses chemical reactions to moderate one or more of these fire elements.

Flame Retardant vs. Flame Resistant: What's the Difference?
Flame-resistant fabrics are made of fibers that naturally resist burning when exposed to flames, whereas flame-retardant fabrics are treated with chemicals to make them resistant to fire, essentially extinguishing any flame that strikes them. Another difference between garments in these two categories is cost.
