Product Introduction

Antioxidant B225 | Composite Hindered Phenol Antioxidant for Polymers

1. Product Introduction

Antioxidant B225 is a high-efficiency composite polymer antioxidant formulated with a scientific ratio of hindered phenolic primary antioxidant and phosphite auxiliary antioxidant. It is composed of Antioxidant 1010 and Antioxidant 168, with dual CAS numbers 6683-19-8 and 31570-04-4. Appearing as fine white crystalline powder at room temperature, this synergistic composite stabilizer integrates excellent long-term thermal aging resistance and outstanding processing anti-oxidation performance, perfectly solving the single protection defect of traditional single-component antioxidants.

As a mainstream universal composite anti-aging additive in the global plastic and polymer industry, Antioxidant B225 features low volatility, excellent color retention and high-temperature stability. It can effectively inhibit thermal oxidation degradation, molecular chain breakage, yellowing and melt viscosity fluctuation of polymer materials during high-temperature extrusion, injection molding and long-term outdoor service. With superior synergistic stabilization effect, it significantly improves processing stability and service life of polyolefins, engineering plastics, elastomers and adhesive products. Our factory-grade Antioxidant B225 boasts high purity, stable batch proportion and excellent resin compatibility, fully compliant with international industrial and environmental standards.

3. Product Features & Applications

Core Product Features

Dual synergistic anti-aging mechanism: Antioxidant B225 combines the long-term thermal stabilization advantage of hindered phenol Antioxidant 1010 and the excellent processing protection performance of phosphite Antioxidant 168. The dual-component synergistic system achieves double protection of high-temperature processing anti-degradation and long-term service anti-aging, far exceeding the performance of single-component antioxidants.
Excellent high-temperature stability & low volatility: This composite antioxidant maintains ultra-low volatility under high-temperature molding and extrusion conditions, avoiding additive loss, product surface blooming and equipment pollution. It effectively resists thermal oxidation during repeated processing and ensures stable product quality for secondary processing materials.
Superior color retention performance: It can significantly inhibit polymer yellowing and discoloration caused by thermal oxidation, maintain long-term color stability of transparent and light-colored plastic products, and solve the aging fading problem of high-gloss polymer materials.
Wide formula compatibility & easy application: Perfect compatibility with polyolefins, engineering plastics, elastomers and adhesive systems. It can be uniformly dispersed in polymer matrices without affecting material physical properties, suitable for various industrial continuous production processes.
Good auxiliary light stability effect: It can form an efficient composite stabilization system with UV absorbers and HALS light stabilizers, significantly improving the weather resistance and outdoor service life of polymer products, ideal for outdoor engineering material formulas.

Main Application Fields

Polyolefin Plastic Industry: Widely used in PP, PE, EVA and polyolefin copolymer materials. It effectively prevents thermal degradation and yellowing during high-temperature processing and long-term aging, suitable for plastic pipes, injection-molded parts, film materials and daily polyolefin products.
Engineering Plastics Field: Applied in ABS, PC, PBT, PA and other modified engineering plastics. It stabilizes melt viscosity during high-temperature processing, improves product mechanical strength retention rate, and extends the service life of automotive plastic parts, electronic and electrical plastic components.
Elastomer & Rubber Products: Suitable for thermoplastic elastomers, synthetic rubber and latex materials. It inhibits thermal oxidative aging and dynamic fatigue aging, reducing hardening, cracking and elasticity attenuation of rubber and elastomer products during long-term use.
Adhesive & Coating Industry: Used in hot melt adhesives, polyurethane adhesives, industrial sealants and high-performance coatings. It prevents adhesive gelation, viscosity change and coating film aging fading, improving product storage stability and weather resistance.
Masterbatch & Polymer Modified Materials: As a universal anti-aging additive for plastic masterbatch, color masterbatch and modified composite materials, it ensures stable processing performance and consistent finished product quality for modified polymer materials.
