Profile: Sapphire Flame Retardants CC manufactures flame retardants and welding blankets. Our flame retardant prevents flame spread , which is one of the important properties for an effective flame retardant on combustible materials. The big hazard with any fire is its ability to spread flames quickly and this causes damage over an infinitely wider area. Our flame retarding product does not stop material from charring in the vicinity of the flame, or in the case of thermoplastic materials such as nylon, from melting. Our products are used in automotive, mining, and marine industries.
