In 2026, China’s domestic PVB interlayer industry will achieve a breakthrough across the entire value chain. From self-developed production of upstream PVB resin and midstream processing of functional film materials to downstream customized applications, the complete industrial ecosystem will continue to mature, reversing the longstanding reliance on imports for optical‑grade and automotive‑grade PVB films.
Previously, China’s PVB industry was dominated by general‑purpose architectural‑grade and standard automotive‑grade films, while core formulations and production processes for optical films and high‑weatherability photovoltaic‑specific films remained underdeveloped, leaving the market firmly in the hands of overseas suppliers. This year, several domestically built, intelligent, high‑precision production lines for functional PVB films have been successfully commissioned. Leveraging refined formulation control, high‑precision cast‑film technology, and a dust‑free, clean‑room manufacturing system, these facilities have achieved performance metrics that rival leading international standards, surpassing competitors in key indicators such as light‑transmittance uniformity, thickness tolerance, weathering stability, and adhesion strength.
As domestic production capacity continues to ramp up, coupled with the advantages of cost efficiency and supply-chain self‑reliance, the localization rate of PVB interlayer in China has been steadily rising. At the same time, substantial volumes are being exported to global markets, serving a wide range of applications in the automotive, construction, and photovoltaic sectors, making it a key export category for China’s new materials industry. Meanwhile, the industry’s capacity structure is undergoing continuous optimization, with low‑value‑added, low‑precision, general‑purpose capacity gradually being phased out in favor of customized, high‑value‑added products.
