For R&D scientists and product formulators, a deep understanding of material properties is crucial for developing high-performance products. Antioxidant 1010 (CAS 6683-19-8) stands out as a highly effective phenolic antioxidant, widely adopted across various industries due to its exceptional chemical properties and broad applicability.

At its core, Antioxidant 1010 is a sterically hindered phenolic compound. This molecular architecture is key to its function as a primary antioxidant. It efficiently traps free radicals generated during thermal or oxidative stress, thereby preventing polymer degradation. The compound's molecular weight of approximately 1177.66 g/mol contributes to its low volatility, a critical factor during high-temperature polymer processing. Unlike lower molecular weight antioxidants, it is less prone to evaporating, ensuring sustained protection within the polymer matrix.

The chemical properties of Antioxidant 1010 also include excellent solubility in common organic solvents like toluene and ethyl acetate, facilitating its incorporation into various formulations. While its solubility in water is negligible, this attribute is advantageous as it resists leaching from the polymer when exposed to moisture. Its melting point typically ranges between 115-118 °C (with decomposition), indicating its stability under moderate processing conditions.

Industrially, Antioxidant 1010 is a favored choice for stabilizing a wide array of substrates, including polyolefins (polyethylene, polypropylene), polyesters, polyamides, PVC, ABS, and various elastomers. Its ability to protect against thermo-oxidative degradation without causing discoloration makes it ideal for applications where aesthetics are important. When you buy this antioxidant, you're investing in enhanced product lifespan and maintained performance characteristics.

Manufacturers and formulators looking to procure this versatile additive should consider suppliers who can guarantee high purity (often >98%) and consistent batch-to-batch quality. Sourcing from reputable chemical manufacturers ensures that you receive a product that meets stringent industry standards, enabling you to develop reliable and durable end products. Exploring options from established suppliers in China can offer competitive pricing and dependable supply chains.
