Bisphenol A: Overview
From headlamp lenses to wind blades and can linings
What this tab covers What the chemical is, how big its market is, what it is used for (with shares, volumes, why it wins and what could replace it), and its chain from raw material to end user. Ends with three things to remember.Bisphenol A (BPA) is made by condensing two molecules of phenol with one of acetone over an acid resin catalyst. About three-fifths goes into polycarbonate for car parts, electronics and glazing, and most of the rest into epoxy resins for coatings, circuit boards and wind turbine blades. World demand is about 7.5 Mt a year (indicative), with China the largest producer and adding most new capacity. The EU banned BPA in food-contact materials from 2025. India makes no BPA today but Reliance plans a 0.5 Mt/yr plant at Jamnagar by 2030 (GlobalData).
Volume about 7.5 Mt a year of demand (2024, indicative, industry estimates) Market value about $9 billion (2024, indicative, basis: 7.5 Mt x about $1,200/t) Growth about 3% a year to 2030 (indicative); Asia plans 2.69 Mt/yr of new capacity in 2025-2030 (GlobalData) GlobalData via Offshore Technology, Nov 2025; volume and value indicativeKey uses
| Use | Share | Annual volume | Why this commodity | Alternatives |
|---|---|---|---|---|
| Polycarbonate | 62% | about 4.7 Mtbasis | Polycarbonate is clear, tough and heat resistant, so it is used for headlamp lenses, glazing, electronics housings and medical devices. Almost all polycarbonate is made from BPA, and large producers integrate BPA with PC. indicative share, industry estimates | PMMA for glazing copolyesters (Tritan) for food contact isosorbide-based polycarbonate |
| Epoxy resins | 30% | about 2.3 Mtbasis | BPA reacts with epichlorohydrin to give epoxy resins for protective coatings, can linings, electrical laminates, adhesives and wind blade composites. They cure hard and resist chemicals. indicative | bio-based epoxies polyurethane and polyester coatings BPA-free can coatings (acrylic, polyester) |
| Flame retardants (TBBPA) | 4% | about 0.3 Mtbasis | Brominating BPA gives tetrabromobisphenol A, a reactive flame retardant in circuit-board laminates. indicative | phosphorus flame retardants |
| Other resins (polysulfone, polyetherimide, phenoxy, unsaturated polyesters) | 4% | about 0.3 Mtbasis | High-performance plastics and specialty resins use BPA for rigidity and heat resistance. indicative | varies |
From raw material to user
- Benzene and propylene to cumene Cumene is oxidised and cleaved to phenol and acetone (1 t phenol with about 0.62 t acetone).
- Condensation About 0.84 t phenol and 0.26 t acetone per t BPA react over a sulphonated ion-exchange resin (indicative; theoretical 0.82 and 0.25).
- Purification Crystallisation of a BPA-phenol adduct gives polycarbonate-grade BPA at 99.9% or better (indicative).
- Polycarbonate Melt transesterification with diphenyl carbonate or interfacial phosgenation.
- Epoxy Reaction with epichlorohydrin gives liquid and solid epoxy resins.

Oil Crude oilThree things to know
- Asia plans 2.69 Mt/yr of new BPA capacity in 2025-2030, 1.91 Mt/yr of it in China (GlobalData).
- Reliance's planned 0.5 Mt/yr Jamnagar plant (2030) would be the largest in Asia and India's first (GlobalData).
- The EU's food-contact ban (Regulation (EU) 2024/3190) follows EFSA's 2023 tolerable daily intake of 0.2 ng/kg body weight, about 20,000 times lower than before (indicative).
