Description

Benzenepropanoic Acid, 3,5-Bis(1,1-Dimethylethyl)-4-Hydroxy-, 1,1'-[2,2-Bis(Hydroxymethyl)-1,3-Propanediyl] Ester is a high-performance, sterically hindered phenolic antioxidant. This compound is valued for its excellent thermal stability and ability to inhibit oxidative degradation in a wide range of polymeric systems. It is primarily utilized by manufacturers in the polymer, plastics, and specialty chemical industries to enhance the longevity and performance stability of their products under demanding conditions.

Application

• Polymer Stabilization: Acts as a primary antioxidant in polyolefins (PP, PE), engineering plastics, and synthetic rubbers to prevent thermal and oxidative degradation during processing and service life.
• Additive for Lubricants and Fuels: Used in formulating industrial lubricants, greases, and fuel additives to improve oxidative stability and extend operational life.
• Adhesives and Sealants: Incorporated into hot-melt adhesives, polyurethane systems, and other sealant formulations to prevent premature aging and maintain adhesive properties.
• Coating Resins: Enhances the durability of alkyd, acrylic, and other coating resins by protecting against oxidative cross-linking and yellowing.
• Elastomer Production: Provides critical antioxidant protection in the manufacture of SBR, NBR, and other synthetic elastomers.
• Masterbatch and Compound Formulation: A key ingredient in antioxidant masterbatches and polymer compounds for consistent and efficient additive dispersion.
