Songflame YA 010 and YA 020 are halogen-free flame retardants based on phosphine oxides that are designed to be reactive with a resin’s backbone (principally epoxies) to give long-term stability. Their key advantages include being environmentally safe, non-toxic and non-corrosive. Songflame TP100 is a halogen-free flame retardant based on phenol/bi-phenol polyphosphate, and is suited to a wide range of thermoplastic resins, particularly polycarbonate, polycarbonate blends with acrylonitrile butadiene styrene (ABS), and a wide range of polyesters.
