Non-BDE FR for flexible PUR foam.

Two new brominated flame retardants for flexible urethane foam from Chemtura Corp., Middlebury, Conn., were incorrectly described in our August issue as being based on BDE chemistry, which is the subject of environmental health concerns. In fact, Firemaster 600 and 602, like their predecessors 550 and 552, are proprietary non-BDE phosphorus-bromine FR agents.

Compared with the earlier offerings, grades 600 and 602 reportedly allow for about 10% lower use levels and exhibit outstanding scorch resistance. Tel: [phone] * PTDirect: 295QX
