For professionals in the chemical and manufacturing industries, identifying and sourcing reliable raw materials is fundamental to product success. Antioxidant 245, identified by its CAS number 36443-68-2, is a high-performance additive crucial for protecting polymers against degradation. If you are in the market to buy this essential compound, understanding its properties and applications will guide your procurement decisions.

Antioxidant 245 is a sophisticated sterically hindered phenolic antioxidant. Its primary function is to inhibit the oxidative breakdown of organic materials, particularly polymers, which can occur during high-temperature processing or prolonged exposure to environmental factors. This protective capability makes it a valuable component for manufacturers aiming to enhance the durability and lifespan of their products. As a leading supplier, we offer this key ingredient to meet the exacting demands of industrial applications.

The technical specifications of Antioxidant 245 underscore its effectiveness. It is typically supplied as a white dispersion liquid, noted for its low odor and minimal volatility. This ensures that it integrates seamlessly into polymer matrices without negatively impacting the final product’s sensory properties or undergoing premature loss during processing. Its high extraction resistance is another critical feature, ensuring that its protective benefits are retained even when the material is exposed to solvents or washing agents.

The application spectrum for Antioxidant 245 is impressively broad. It is a preferred choice for stabilizing a variety of polymers, including impact-modified polystyrenes (HIPS), ABS, and MBS resins, contributing significantly to their thermal stability and resistance to yellowing. Furthermore, its utility extends to engineering plastics like Polyoxymethylene (POM) and Polyamides (PA), where maintaining mechanical properties over time is vital. For those in the polyurethane sector, Antioxidant 245 is a valuable additive for products such as spandex and various adhesives and sealants, enhancing their overall performance and longevity.

A notable application of Antioxidant 245 is its role in PVC polymerization. It functions as an effective chain terminator, helping to control the reaction kinetics and thus the molecular weight distribution of the resulting PVC polymer. This precise control is crucial for achieving the desired physical and processing characteristics in PVC products.
