GON-9228

ZX-9228 phosphite ester antioxidant showcases excellent hydrolysis resistance, volatility resistance, and thermal processing stability. Even under prolonged exposure to humidity, it withstands hydrolysis, maintaining particle form and free-flow properties. In synergy with light stabilizers, it preserves polymer color while reducing melt degradation. ZX-9228 is widely applied in specialty engineering plastics, enhancing processing thermal stability, color stability, and melt flow stability.
