YINOX^® 235 is a widely applicable liquid hindered phenol antioxidant, particularly renowned for its outstanding antioxidant performance in the polyurethane industry. It effectively prevents the formation of peroxides in polyether polyols during storage, thereby inhibiting yellowing, and also prevents the occurrence of burn-through during polyurethane foaming processes. When added to PU footwear materials, synthetic leather, and elastomers, it significantly enhances the product's resistance to yellowing. YINOX^® 235 is a flowing liquid at room temperature, with low volatility and excellent compatibility, making it particularly suitable for use in the manufacturing and processing of single liquids, emulsions, suspensions, or solutions of polymers, such as PVC stabilizers, rubber, lubricants, and other materials.
