BLS 234 (70321-86-7)is a low volatile, benzotriazole type, ultraviolet light absorber (UVA), which is highly effective for polymers being processed at high temperatures. BLS 234 is especially suited for polycarbonates and polyesters. It protects the polymers from UV radiation helping to preserve the original appearance and physical integrity.
