Technical Specification for the Selection of PVB Interlayer in Laminated Glass
PVB film is the core component of laminated glass; choosing the right thickness doubles its safety. Standard thicknesses are 0.38 mm, 0.76 mm, 1.14 mm, 1.52 mm, and 2.28 mm, with a tolerance of ±0.03 mm. For architectural applications, PVB film must meet the following performance criteria: volatile organic compound content of 0.35%–0.55%, tensile strength ≥ 20 MPa, elongation at break ≥ 250%, and light transmittance ≥ 85%.

Today, market demand for PVB interlayers has shifted from “basic safety” to a composite requirement that combines “long‑term stability” with “additional functionalities.” The commercialization of weather‑resistant, anti‑fouling, and functionalized products has further expanded the PVB film 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.

As automotive intelligence and in-cabin technology continue to advance, features such as AR‑HUDs, smart dimming windows, and panoramic smart sunroofs are rapidly gaining traction. Consequently, market demand for optical PVB interlayers is experiencing explosive growth, making this a high-value, fast‑growing niche within the PVB industry and driving the sector’s expansion and upgrade from basic materials into the realm of advanced optical materials.

Traditional PVB film production has been characterized by high energy consumption and the use of less environmentally friendly additives. This year, the industry’s leading producers have adopted green manufacturing processes, optimizing synthesis formulations, incorporating eco‑friendly additives, and upgrading to energy‑efficient equipment, thereby significantly reducing both energy use and pollutant emissions and achieving decarbonization across the entire production chain.
