Korean company Songwon has introduced a number of new halogen-free flame retardants. Songflame YA 010 and YA 020 are based on phosphine oxides. The company says that they are designed to be reactive with the resin backbone, principally epoxies, to give long term stability with the key advantages of being environmentally safe, non toxic and non corrosive. End-use application for glass reinforced printed circuit boards.
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 ABS and a wide range of polyesters. This new molecular structure, having a higher glass transition temperature, has the key advantage of boosting the thermal strength properties in the resin matrix.
