In the demanding world of polymer manufacturing, ensuring the longevity and performance of materials is paramount. One of the key challenges faced by compounders and formulators is oxidative degradation, a process that can compromise the structural integrity and aesthetic appeal of plastics over time. To combat this, high-performance antioxidants are indispensable. Among these, Distearylamine (SA86) stands out as a versatile and effective solution.
As a leading manufacturer of fine chemical intermediates, we specialize in producing high-purity Distearylamine (SA86), a secondary amine featuring two long C18 alkyl chains. This unique molecular structure imbues SA86 with exceptional antioxidant properties, making it an ideal additive for a wide range of polymer systems, including Polypropylene (PP) and Polyethylene (PE). When incorporated into these polymers, SA86 acts to scavenge free radicals generated during processing and over the product's lifecycle, thereby preventing chain scission, cross-linking, and discoloration.
The effectiveness of Distearylamine (SA86) as an antioxidant stems from its ability to interrupt the auto-oxidation chain reaction. During processing at elevated temperatures or upon prolonged exposure to UV light and heat, polymers can undergo oxidation, leading to a breakdown of their molecular structure. SA86, as a hindered amine, can donate a hydrogen atom to peroxy radicals, stabilizing them and forming relatively unreactive species. This action effectively terminates the degradation cycle, preserving the polymer's mechanical properties, such as tensile strength, impact resistance, and elongation at break.
Beyond its primary role as an antioxidant, SA86 also contributes to the overall stability and processability of polymers. Its presence can help to mitigate thermal degradation during extrusion and molding processes, leading to improved manufacturing efficiency and reduced scrap rates. For formulators seeking a reliable supplier of this critical additive, partnering with an experienced manufacturer in China ensures not only competitive pricing but also a consistent supply of high-quality material. We understand the stringent requirements of the polymer industry and are committed to providing Distearylamine (SA86) that meets exact specifications. Whether you are looking to buy SA86 for existing formulations or exploring new applications, our team is ready to assist you with technical support and tailored solutions.
