How Large Is the Global Plastic Antioxidants Market, and What Is Driving Its Growth? – (Updated On: 28th-Oct-2026)

According to Strategic Market Research, the global Plastic Antioxidants Market is projected to reach USD 1.50 billion by 2032, compared with an estimated USD 1.07 billion in 2025. This represents a compound annual growth rate (CAGR) of approximately 5.0% during 2026–2032, supported by continued polyethylene and polypropylene production, increasing requirements for long-term thermal stability in automotive and industrial plastics, and the growing use of antioxidant stabilization systems in recycled polymers to maintain material quality during reprocessing.

 

In 2025, global polyethylene production reached approximately 125 million metric tonnes, according to China Chemical Industry Information Weekly, while polypropylene production stood at 88.39 million metric tonnes, as reported by Formosa Plastics Corporation. Together, these polymers represented approximately 213.39 million metric tonnes of annual production, reflecting the substantial volume of plastics manufactured using antioxidant stabilization systems. The quantity of antioxidants required depends on the polymer and its processing conditions. For example, BASF recommends adding 1–2.5 kilograms of its Irganox B 225 antioxidant blend per metric tonne of polyolefin. This demonstrates how relatively small quantities of antioxidants are used across large polymer manufacturing volumes, generating substantial demand for these additives.

 

Asia plays an important role in this market because of its large polyethylene and polypropylene manufacturing industries. According to PlasticsEurope, China accounted for 34.5% of global plastics production in 2024, while India's Department of Chemicals and Petrochemicals reported approximately 11.39 million metric tonnes of combined polyethylene and polypropylene production in FY2024–25. These manufacturing volumes support demand for antioxidants used to maintain polymer quality during resin production and conversion. In addition, the growing use of recycled polyethylene and polypropylene creates opportunities for antioxidant formulations that help restore processing stability and protect recycled polymers from further degradation.
