In the processing and application of polymer materials, thermal oxidative degradation, high-temperature yellowing and performance attenuation are core problems that restrict the quality and service life of products. With the iterative upgrading of engineering plastics, high-end elastomers and precision rubber and plastic products industry, the market has put forward higher requirements for the high-temperature resistance, stability and compatibility of additives. As a benchmark product of high-end phosphorus-containing auxiliary antioxidants, PEPQ Antioxidant has become a preferred core additive for the production and processing of high-end polymer materials due to its excellent thermal stability, superior anti-yellowing performance and broad compatibility, and is widely used in the production of various high-performance polymer products.

PEPQ is a high-efficiency phosphite auxiliary antioxidant, appearing as white crystalline powder. It boasts industry-leading high-temperature resistance with a thermal decomposition temperature of over 300°C and a maximum thermal weight loss temperature of 350°C. It can perfectly adapt to harsh processing scenarios such as high-temperature extrusion, injection molding, modification and recycling of various polymer materials, inhibit the thermal oxidative decomposition of materials from the source, and solve the pain points of traditional antioxidants such as easy volatilization, decomposition and failure of protection at high temperatures.

Compared with ordinary antioxidant products, PEPQ Antioxidant has multiple core advantages that accurately meet the production needs of high-end materials. Firstly, it features ultra-high thermal stability and low volatility. It is non-volatile, non-decomposable and non-precipitating during high-temperature processing, which can stably exert a protective effect for a long time, effectively avoid product quality defects such as black spots, bubbles and color difference, and greatly improve the product qualification rate.

Secondly, it has excellent anti-yellowing and color stability, which is the core differentiated advantage of PEPQ. For materials with extremely high requirements on appearance and color such as polycarbonate, optical plastics and transparent elastomers, it can effectively inhibit yellowing during processing and long-term service, stabilize the light transmittance and appearance texture of products, accurately improve the melt index of materials, and ensure consistent color of products in batch production.

In addition, the product has the characteristics of hydrolysis resistance, low migration and high compatibility. It is highly compatible with most polymer resins and will not affect the mechanical properties, light transmittance and processing properties of the materials themselves. In practical applications, the compound use of PEPQ with hindered phenolic primary antioxidants can produce a strong synergistic effect, comprehensively improve the processing stability and long-term aging resistance of materials, and greatly extend the service life of products.

Thanks to its superior comprehensive performance, PEPQ Antioxidant is compatible with most general plastics, engineering plastics, elastomers and polymer adhesives with a wide range of applications. In the engineering plastics field, it is applicable to PC, PET, PBT, PA, polyphenylene oxide, polyphenylene sulfide and other materials. It is especially suitable for optical-grade transparent PC products, which perfectly solves the high-temperature yellowing problem of precision injection molded parts, transparent plates and optical accessories. Meanwhile, it adapts to plastic recycling and regeneration processing to stabilize the viscosity and color of recycled materials.

In the field of general plastics and elastomers, it is widely used in PP, PE, ABS, EVA, polyolefin copolymers and other products, which effectively improves the thermal processing stability of materials and prevents aging embrittlement and performance attenuation. It can also be applied to high-end adhesives and coating polymers to meet the anti-oxidation and anti-discoloration requirements under high-temperature curing processes.

In terms of industrial production, PEPQ Antioxidant has significant cost advantages with a conventional addition ratio of only 0.1%-0.5%. A very low dosage can achieve efficient protection, which will not greatly increase raw material costs while improving product quality. In addition, the product has stable storage performance, is not easy to agglomerate due to moisture, and has strong processing adaptability. It can be directly put into use without changing the original production process, adapting to large-scale and standardized industrial mass production procedures.

With the comprehensive advantages of high temperature resistance, anti-yellowing, low volatility, strong synergistic effect and wide compatibility, PEPQ Antioxidant has become a star product in the high-end rubber and plastic additives industry, and replacing traditional ordinary antioxidants has become an industry mainstream trend. In the future, as polymer materials continue to develop towards high-end, precision and recyclable directions, PEPQ Antioxidant will continuously empower rubber and plastic, electronics, optics, automobile, building materials and other industries, helping terminal products achieve quality upgrading and service life extension.
