Polycarbonate Sheet Industry: At an Inflection Point, Led by High-End & Green Development

In 2025–2026, China’s polycarbonate (PC) sheet industry is undergoing a key transition from scale expansion to value upgrading. With an optimized supply and demand structure, accelerated technological innovation and expanded application scenarios, the industry has entered a new stage of profit recovery and high-quality development.

On the supply side, following years of concentrated capacity expansion, China entered a capacity expansion lull in 2026, with sharply slowed new capacity and industry operating rates steadily rising above 85%. Leading enterprises have accelerated the integration of upstream bisphenol A production, with 72% of capacity achieving self-sufficiency in raw materials, significantly easing cost pressure. China’s import dependence has dropped to 24%, shifting from a net importer to a net exporter, strengthening its voice in the industrial chain. Major producers have shifted from price competition to coordinated quality improvement, widening price differentials and restoring profit margins.

On the demand side, architectural daylighting systems (greenhouses, carports, pool covers, skylights) remain the main market, accounting for about 45%. Emerging sectors such as new energy vehicle lightweighting, photovoltaic and energy storage casings, rail transit and high-end optics are rapidly rising as growth engines. Benefiting from high light transmittance, impact resistance, thermal insulation, weather resistance and light weight, PC sheets enjoy growing penetration in BIPV, automotive transparent parts and smart greenhouses, with emerging applications accounting for 18% in 2025.

Technologically, the industry focuses on high performance and green development. Functional products such as multi-layer co-extruded UV protection, anti-fog, self-cleaning and flame-retardant sheets are in mass production. Bio-based PC and chemical recycling technologies have been applied to support low-carbon transformation. High-end optical PC and high heat-resistant modified sheets have broken foreign monopolies, accelerating domestic substitution.

Looking ahead to 2026–2030, driven by carbon neutrality, new urbanization and self-reliance in high-end manufacturing, the PC sheet market will grow by over 7% annually. High-end, green and customized products will be the core trends, with enterprises possessing integrated industrial chains, R&D and environmental advantages leading the market.
