Description

Benzoic Acid, 2-Hydroxy-, Polymer With 4-(1,1-Dimethylethyl)Phenol And Formaldehyde is a phenolic resin polymer derived from salicylic acid, *tert*-butylphenol, and formaldehyde. This specialized polymer is valued for its excellent thermal stability, chemical resistance, and ability to function as an antioxidant and metal deactivator in demanding industrial formulations. It is primarily utilized by manufacturers in the polymer, lubricant, and fuel additive industries seeking to enhance product longevity and performance under oxidative stress.

Application

• Polymer Additive: Acts as an antioxidant and stabilizer in plastics and elastomers to prevent thermal and oxidative degradation.
• Lubricant Industry: Used as an additive in industrial oils and greases to inhibit oxidation and sludge formation, extending equipment life.
• Fuel Additive: Functions as a stabilizer and metal deactivator in gasoline and diesel fuels to prevent gum formation and oxidation.
• Adhesives and Coatings: Serves as a modifying resin to improve adhesion, thermal resistance, and durability in high-performance formulations.
• Rubber Compounding: Employed as a non-staining antioxidant in various rubber products to maintain elasticity and prevent cracking.
• Industrial Preservative: Provides protective properties in functional fluids and process streams susceptible to oxidative breakdown.
