Richvin 770 excellent compatibility with most polymers. It can be incorporated into the polymer in a conventional way. it shows synergistic effect by the combined with benzotriazole or benzophenone type uv-absorbers. To achieve maximum effect with Richvin 770 it is important to provide the polymer with sufficient basic stabilization to prevent thermooxidative degradation. In addition, certain components of heat stabilizer systems, particularly phosphites, and hindered phenol type antioxidants are recommended as basic stabilizer.
