Description

3,5-Di-tert-Butyl-4-Hydroxybenzyl Propionate is a high-performance hindered phenolic antioxidant widely used to inhibit oxidative degradation in various polymeric systems. Its primary value lies in its ability to extend the service life and maintain the physical properties of materials exposed to heat and light. This compound is essential for manufacturers in the plastics, rubber, and specialty chemical industries seeking to enhance product durability and stability.

Application

• Primary antioxidant for polyolefins, including polyethylene (PE) and polypropylene (PP).
• Stabilizer for synthetic rubbers, such as styrene-butadiene rubber (SBR) and polybutadiene.
• Additive in adhesives and sealants to prevent premature aging and maintain elasticity.
• Stabilizing component in lubricating oils and greases to reduce oxidative thickening.
• Protective agent for engineering plastics like ABS (Acrylonitrile Butadiene Styrene).
• Used in the formulation of masterbatches and polymer concentrates for consistent additive dispersion.
