Comparative photographs show the dramatic fire-resistant impact of adding a tiny amount of nonhalogen Flamestab NOR116 retardant and synergist to the fibers of polypropylene cloth. Thirty-five seconds after flame removal, the test sample with out the new additive burns intensely, although the protected material remains intact. Ciba Specialty Chemicals Corp. The threatened bans on halogen flame retardants have not materialized in North America. These old standbys are holding their own, and new developments and marketplace entries reflect a growing accepted technologies. Still, the nonhalogens are generating inroads in chosen locations, despite the fact that their expense and functionality have not kept pace with these of the more effective halogen products. In Europe, nonetheless, the story is different. The nonhalogen flame retardants are thriving, and the halogen-based additives are beneath escalating restrictions due to the fact of environmental perceptions. Geographical variations The market for flame retardants is a expanding at an annual rate of 4% to 6%, says Russ Kidder, executive vice president of the Fire Retardant Chemical substances Association (FRCA). The Europeans are willing to settle for significantly less fire safety rather than to use brominated flame retardants. This is observed most significantly in tv sets, which, for the most component, contain no flame retardant at all. As a single may possibly count on, Tv fires have enhanced drastically because flame retardants have been eliminated from Television sets in Europe. In the U.S., television sets and some unattended appliances, contain halogenated flame retardants in these applications, fire security is at high levels. In most appliances exactly where nonhalogenated flame retardants are utilized, either the flammability rating or physical properties are below U.S. standards. Nonhalogenated flame retardants are receiving much more investigation effort in the United States and have produced some inroads in the market spot.

High efficiency permits lowered use levels. FyrolCLP, containing chlorine and phosphorus, is being evaluated whereflame-retarded flexible polyurethane foams are utilized.The company expanded capacity of Fyrol PCF and Fyrol CEF, keyflame retardants utilized in rigid polyurethane foams. The trend towardhydrocarbon blowing agents in spot of fluorocarbons to comply with theMontreal Protocol has resulted in the incorporation of further flameretardant to meet flammability requirements. Volume expansion in the firstquarter of 2001 will enhance the availability of Fyrol FR2 and Fyrol38, products utilized in the flexible polyurethane foam industry. In therecent previous, the development price of flame retardants in the flexible foam  market place has been just above GNP rates.
