Flame Retardants Exolit OP 560

No Compromise

In the furniture and beddings industry, large quantities of non-reactive flame retardants are usually employed for polyurethane flexible foams. While these are mixed into the foam only physically, they can migrate out of the foam matrix, and are associated with adverse environmental and health effects.

Clariant International Ltd., Muttenz, Switzerland, recently developed a flame retardant, Exolit OP 560, which is based on liquid phosphonate. It reacts chemically with the PU foam polymer, remaining non-migrating in the foam formula. It thus also reduces volatile organic compounds (VOCs). The high efficiency of the phosphonate along with its good polymer compatibility permits for low dosage in the foam matrix. What is more, the amount of flame retardant can be reduced by 80 %. Other benefits are outstanding ageing resistance, low smoke density and low smoke gas corrosivity, in addition to good recyclability. According to company information, Exolit OP 560 supports the upholstery sector in their changeover to renewable materials and environmental compatibility.
