The performance and lifespan of polymeric materials are often determined by the specialized additives incorporated during their manufacturing. Among these, antioxidants are crucial for preventing degradation caused by exposure to heat, light, and oxygen. Antioxidant 330, chemically known as 1,3,5-Trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzene and identified by CAS 1709-70-2, is a high-performance hindered phenolic antioxidant widely utilized across the industry. Understanding its role and benefits is key for any professional involved in polymer formulation or procurement.

This compound's primary function is to interrupt the auto-oxidation process that leads to polymer breakdown. It achieves this by donating a hydrogen atom from its phenolic hydroxyl group to peroxy radicals, thereby terminating the chain reaction. Its highly sterically hindered nature ensures its stability and effectiveness, even at elevated temperatures encountered during polymer processing. As a leading supplier of this vital additive, we aim to provide clear insights into its applications and the advantages of purchasing from a reliable source in China.

The applications for Antioxidant 330 (CAS 1709-70-2) are extensive. It is particularly effective in polyolefins such as polyethylene (PE) and polypropylene (PP), used in everything from durable pipes and automotive parts to packaging films. It also finds significant use in engineering plastics like polyamides and polyesters, as well as in elastomers, adhesives, and synthetic fibers like spandex. Its good compatibility and low extractability make it a preferred choice for food-contact applications and where long-term thermal stability is critical.

For businesses seeking to buy this crucial polymer stabilizer, sourcing from a reputable manufacturer like NINGBO INNO PHARMCHEM CO., LTD. offers distinct advantages. We emphasize quality control and consistent production, ensuring that each batch meets stringent purity standards.
