Polycarbonate: Overview
From laptop chargers to headlamps and roofing sheets
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.Polycarbonate (PC) is made by linking bisphenol A (BPA) with either phosgene or diphenyl carbonate. It is transparent, very tough and heat-resistant, so it replaces glass in headlamp lenses, roofing sheets, safety glazing and device housings. Global demand including blends passed 5 Mt for the first time in 2024, at 5.2 Mt, against about 7.7 Mt of capacity, with about 4% a year growth expected (Plastics Insights via findoutaboutplastics, Nov 2025). China went from 5 polymerisation plants in 2015 to 17. India imports all of its PC, more than 300 kt a year, until Deepak Chem Tech's 165 kt/yr plant starts in FY2027-28 to FY2028-29.
Volume about 5.2 Mt of demand including blends (2024) Market value about $10 billion (2024, indicative, basis: 5.2 Mt x about $2,000/t) Growth about 4% a year Plastics Insights via findoutaboutplastics.com, Nov 2025; value indicativeKey uses
| Use | Share | Annual volume | Why this commodity | Alternatives |
|---|---|---|---|---|
| Electrical and electronics | 35% | about 1.8 Mtbasis | PC and PC/ABS make laptop and charger housings, connectors, LED lenses and light diffusers. It is tough, flame-retardant in thin walls and dimensionally stable. Plastics Insights via findoutaboutplastics, Nov 2025 | PC/ABS blends PMMA for optical parts modified PPE |
| Automotive | 20% | about 1.0 Mtbasis | Headlamp lenses, interior trims, panoramic roofs and EV charging parts use PC because it is clear, light and survives impact. Coated PC glazing weighs about half as much as glass (indicative). Plastics Insights via findoutaboutplastics, Nov 2025 | glass PMMA (rear lamps) PC/PBT blends |
| Construction (sheet and glazing) | 15% | about 0.8 Mtbasis | Multiwall and solid PC sheet for skylights, greenhouses, noise barriers and security glazing combines light transmission with impact resistance. Plastics Insights via findoutaboutplastics, Nov 2025 | glass PMMA sheet PVC sheet |
| Consumer goods | 10% | about 0.5 Mtbasis | Kitchen appliances, luggage, eyewear lenses and power tools use PC for toughness and clarity. Plastics Insights via findoutaboutplastics, Nov 2025 | copolyesters (Tritan) ABS polypropylene |
| Medical, optics, sports, toys and packaging | 20% | about 1.0 Mtbasis | Medical housings, dialysis parts, optical discs, helmets and water-cooler bottles. Food-contact use is shrinking after the EU BPA ban. Plastics Insights via findoutaboutplastics, Nov 2025 | copolyesters PET cyclic olefin copolymers in medical |
From raw material to user
- Benzene and propylene to phenol and acetone Cumene process; about 0.87 t benzene and 0.47 t propylene per t phenol (phenol tile).
- Bisphenol A About 0.84 t phenol and 0.26 t acetone per t BPA (BPA tile); polycarbonate takes 62% of BPA.
- Carbonate source Phosgene from carbon monoxide and chlorine (interfacial route) or diphenyl carbonate (melt route).
- Polymerisation About 0.9 t BPA per t PC (stoichiometric).
- Compounding and sheet extrusion Blends with ABS or PBT, flame retardants and UV stabilisers; sheet is extruded and coated.

- Global PC demand including blends reached 5.2 Mt in 2024 against about 7.7 Mt of capacity; Covestro and SABIC hold over 40% of capacity (Plastics Insights via findoutaboutplastics, Nov 2025).
- China's PC exports doubled from about 250 kt/yr to 500 kt/yr as its plants grew from 5 to 17 (same source).
- India imports all of its PC, more than 300 kt a year; Deepak Chem Tech's 165 kt/yr Dahej plant, built with Trinseo's Stade equipment, is due in FY2027-28 to FY2028-29 (Deepak Nitrite, 2024-2026).
