Antioxidant 1135
Antioxidant 1135, identified by CAS 125643-61-0, is a high-molecular-weight hindered phenolic antioxidant primarily utilized for its excellent thermal stability and low volatility. Chemically, it consists of benzenepropanoic acid derivatives with branched alkyl chains, which contribute to its liquid state at room temperature. This physical form offers significant handling advantages in industrial environments, allowing for easy dosing, blending, and pumping compared to traditional solid antioxidants.
As a primary antioxidant, it functions by scavenging free radicals generated during the thermal-oxidative degradation of polymers and organic substrates. Its chemical structure provides a high degree of compatibility with a wide range of organic materials, ensuring uniform distribution and effective protection. This material is particularly valued in manufacturing contexts where color stability and resistance to scorching are critical requirements for the final product.
• In the production of flexible polyurethane foams, this liquid antioxidant is highly effective at preventing core scorching during the exothermic polymerization process. Its low volatility ensures that it remains active within the polymer matrix even at elevated temperatures, protecting the foam from discoloration and degradation during both the manufacturing and curing stages.
• It is extensively used as a stabilizer for various lubricants and functional fluids, including engine oils and industrial greases. By inhibiting the oxidative thickening and sludge formation that occur under high-temperature stress, it helps maintain the viscosity and performance integrity of the lubricant, thereby extending the service life of mechanical components.
• The material serves as a processing and long-term thermal stabilizer for a variety of elastomers and synthetic rubbers. Its liquid nature facilitates rapid incorporation into polymer melts or solutions, providing protection against oxidative aging and maintaining the physical properties, such as elasticity and tensile strength, of the finished rubber goods.
• It is frequently employed in the stabilization of adhesives and sealants, particularly those based on thermoplastic elastomers or hot-melt formulations. By preventing the degradation of the resin backbone during high-temperature application, it ensures that the adhesive maintains its bonding strength and avoids yellowing or brittleness over time.
