Halogen-Free and Environmentally Compatible
Songwon Industrial Co., Ltd., Ulsan, Korea, is introducing three new halogen-free flame retardants for a large number of key plastics and their end applications. The flame retardants Songflame YA010 and YA020 are based on phosphine oxides and are designed to react with the chief molecules of the plastics – primarily epoxy resins – to form structures with long-term stability. The main advantages of the new products are their environmental compatibility and their non-toxic and non-corrosive behavior in the event of a fire. These core characteristics make them ideal for use in glass-fiber reinforced polymers for the production of printed circuit boards.
The halogen-free flame retardant Songflame TP100 is based on phenol / biphenol polyphosphate and is suitable for a large number of thermoplastics, and especially for polycarbonate, PC blends with ABS and several other polyesters. The new molecular structure of the flame retardant is manifested through a higher glass transition temperature, which serves to optimize the thermal strength of the polymer matrix, in particular.
