Halogen Free Flame Retardants: An Exciting Future for FR
A flame retardant (FR) is an additive that is added to plastic in order to enhance its ability to delay flames and prevent flames from spreading. Flame retardant additives are added during the plastic product manufacturing process. Once flame retardants are introduced to the polymer, the product is considered "fire-safe".
