Not surprisingly, flame retardant materials are used wherever an application exists that has a fire risk scenario. This means that wherever a polymeric material is used near a potential fire source (spark, open flame, or heat source), some level of fire. Fire Retardancy of Polymeric Materials (2nd Edition) Details When dealing with challenges such as providing fire protection while considering cost, mechanical and thermal performance and simultaneously addressing increasing regulations that deal with composition of matter and life cycle issues, there are no quick, one-size-fits-all answers.

Our non-halogenated flame retardants provide environmentally more compatible protection for buildings, electric and electronic equipment as well as textiles and other materials used in aeroplanes, trains, busses and ships. Clariant’s portfolio is based on phosphorus chemistry, with production sites in Knapsack, Germany, Muttenz, Switzerland and Lufeng, China.
Flame retardants based on wheat starch modified with phosphate/urea systems were tested for the first time as additives for wood fiber material. Their flame-retardant properties were extensively characterized with small burner and smoldering tests, thermogravimetric analysis, and cone calorimeter, as well as pyrolysis combustion flow calorimeter.
Demand for nonhalogenated flame retardants in wire and cable applications has been increasing considerably in recent years due to regulation and environmental and health concerns of halogen-based flame retardants. As a result, nonhalogenated phosphorus flame retardants are increasingly being used as the more environmentally friendly.
