Styrenated phenol is a polymer formed by the chemical bonding of phenol and styrene, also known as Antioxidant SP or Antioxidant SP. It exhibits typical aromatic compound solubility, good chemical stability, and moderate resistance to light and heat. It is resistant to oxidative decomposition and can be stored long-term in neutral or weakly acidic environments. It features non-discoloration, non-staining properties, and low volatility.
