In 2026, the industry achieved another breakthrough in the field of functional PVB interlayers: a new-generation, highly weather‑resistant, self‑cleaning, and anti‑fouling modified PVB interlayer has completed process optimization and entered mass production. This innovation addresses key challenges of conventional materials—such as dust accumulation during prolonged outdoor exposure, poor resistance to acids and alkalis, and surface aging that leads to haze—while significantly meeting the demanding requirements of long‑term outdoor applications, including curtain walls, photovoltaic skylights, and landscape glass.
The new modified PVB interlayer, through synergistic optimization of surface functional modification and internal formulation, retains its original explosion‑proof, adhesive, and impact‑resistant properties while adding hydrophobic anti‑fouling, acid‑rain corrosion resistance, and salt‑spray erosion resistance. It resists the accumulation of dust, water stains, and grime during prolonged outdoor exposure, maintaining high light transmittance and clear visual performance over time. Moreover, the product exhibits enhanced weathering and aging resistance; under harsh conditions such as intense UV radiation, alternating day–night temperature cycles, and coastal environments with high salt‑spray concentrations, it effectively delays yellowing, whitening, and delamination—significantly extending the service life of laminated glass assemblies.
In terms of process compatibility, the new functional film is compatible with mainstream lamination processes—such as high-pressure and wet‑process methods—used in current laminated glass production. It can be scaled up for mass production without requiring major modifications to existing production lines, making it suitable for large‑scale applications across multiple sectors, including architectural construction, outdoor photovoltaic systems, public‑facility glazing, and outdoor landscape‑building materials. Compared with conventional products, the long‑lasting, weather‑resistant PVB interlayer significantly reduces subsequent cleaning and maintenance costs as well as glass replacement expenses, offering substantial economic benefits and practical value.
Industry analysis indicates that market demand for PVB interlayers has shifted from “basic safety and protection” to a composite requirement encompassing “long‑term stability plus additional functionalities.” The commercialization of weather‑resistant, anti‑fouling, functionalized products has further expanded the PVB film segment’s product portfolio and provided robust technical support for the industry to tap into outdoor building‑material and photovoltaic‑system markets. Going forward, these advanced films are expected to gradually replace conventional weather‑resistant grades, becoming the mainstream choice for outdoor applications.
