Market overview

Antioxidant 1010 (pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate), CAS 6683-19-8) is the most widely used primary antioxidant for polyolefins and engineering plastics. It protects polymer during processing and service, and is usually used together with phosphite 168.

The question this report answers
How much antioxidant 1010 does polyolefin growth need, and who sets price?

Market Krystal preliminary estimate (2025)
No reliable recent figure. Assuming 120-150 kt at USD 4,000-5,000/t, we estimate USD 0.5-0.75 bn. Confidence grade C: no reliable published figure; range built from the stated assumptions and narrowed in the full report.

Market dynamics
– Demand: polyolefins, engineering plastics
– Supply: BASF, Songwon, Adeka, SI Group, Rianlon
– Price and margin: Chinese supply sets price
– Regulation and substitution: food-contact approvals

Key figures at a glance (third-party, cited)
– Plastic antioxidants market: USD 2.0 bn (2020) to USD 2.6 bn by 2025 at 5.3% CAGR (MarketsandMarkets)
– Producers include BASF (Irganox 1010), Songwon, Adeka, SI Group, Clariant, Sumitomo, 3V Sigma and Dover (MarketsandMarkets)

What this means for the market
Demand follows new polyolefin capacity in China and the Middle East. Prices are under pressure from Chinese supply; Western producers compete on blends and service.

How published estimates compare
The MarketsandMarkets figure covers all plastic antioxidants and is now dated. Market Krystal sizes 1010 by tonnes from polyolefin production and loading, and tracks Chinese capacity.

Strategic scenarios to 2047
– Base: plastics and compounds grow with packaging, automotive, electrical and construction demand; additive volumes follow polymer output.
– Constrained supply: Chinese additive producers dominate volume, so trade measures or plant closures cause regional shortages.
– Technology transition: halogen-free, phthalate-free and recycling-compatible additives take share as regulations and brand targets tighten.
The swing factor for Antioxidant 1010 is polyolefin capacity and recycling-stable grades. Signposts: REACH restrictions, recycling mandates, EV and electronics FR standards, anti-dumping cases.

What this report delivers
Annual volume (tonnes) and value (USD) for 2026-2035, segmented by form: powder, granules, blends (with 168); application: polyolefins, engineering plastics, adhesives, elastomers, lubricants; region: China, Middle East, North America, Europe, India. Each segment is backed by a producer capacity table, price benchmarks for 2020-2025 by grade and region, trade-flow analysis and a supplier risk map. Companies assessed include BASF, Songwon, Adeka, SI Group, Rianlon, Clariant. The 2036-2047 outlook uses three explicit scenarios (base, constrained supply and technology transition) rather than a single extrapolated curve.

Who uses this report
Polyolefin producers, additive makers and investors.

Why our approach is evidence-based
Most CAS-level market listings publish a single number with no audit trail, and we regularly find figures that contradict their own growth rates or exceed the size of the market they sit inside. Market Krystal works the other way round. We start from physical evidence: plant capacities, production and trade data, company disclosures, regulatory texts and price records. We build volume and price separately and only then compute value. Every third-party figure is cited, every Market Krystal estimate is labelled with its method and a confidence grade, and conflicts between sources are shown rather than hidden. Confidence grades: A = two or more independent sources agree, or government or company data; B = one published estimate checked against volumes or prices; C = no reliable published figure, so the range is built from stated assumptions and narrowed in the full report.

Methodology and delivery
Prepared by the Market Krystal Chemicals Research Team. Each report is built around the buyer’s question: after purchase, a short scope confirmation fixes the priority regions, companies and applications, and the report is delivered within 5-7 business days with the Excel model behind every estimate, so buyers can audit and change the assumptions.

The purchased delivery includes the PDF report, Excel datasets and customization around the buyer’s priority region, company set, application or commercial question.
