Non-blooming, stabilized flame retardant compositions and method of flame retarding polyolefins

摘要

A unique blend of brominated flame retardants, an antioxidant process stabilizer that exhibits low surface migration (surface bleeding) and prevents the degradation of physical properties and/or color even under accelerated oven testing, while maintaining good flame retardancy despite the fact that one of the flame retardant components may show exudation when used by itself. The brominated flame retardant composition includes two or more flame retardant components, and must contain at least one oligomeric flame retardant. The oligomeric flame retardant component (component (a)) should contain aromatic bromine or a combination of aromatic bromine and aliphatic bromine while the monomeric or dimeric flame retardant component (component (b)) should contain aliphatic bromine, and may contain a mixture of aliphatic bromine and aromatic bromine.
