Product Description
Product Overview
The Westglass Thermochromic Sunshade PVB Film Series is engineered with 80% polyvinyl butyral (PVB) resin powder and 20% photothermal polymer nano-materials, specifically designed for safety laminated glass applications. Using 25°C as the baseline, the film's base color reversibly adjusts its optical properties and color (transitioning from clear to blue/gray) in response to ambient temperature changes, while maintaining the same bonding strength and safety performance as traditional PVB interlayers.
Through high-temperature, high-pressure lamination processes, it forms a robust "glass-PVB-glass" composite structure, delivering four core functions: intelligent color change, explosion resistance, noise reduction, and energy efficiency. This makes it ideal for curtain walls, skylights, windows, and various glazing applications, seamlessly integrating with different glass types to create customizable smart safety glass for shading, thermal insulation, and energy conservation.
Key Advantages
- Smart Temperature Indication: Visually reflects temperature changes through color transitions, providing clear visual cues for early anomaly detection in industrial settings
- Energy-Efficient Thermal Regulation: Darkens in warm environments to block solar heat (reducing AC load by up to 30%) and lightens in cool environments to allow natural sunlight, achieving 20%-30% energy savings
- Superior Optical Performance: Maintains ≥85% light transmittance in light state and ≥30% in colored state, ensuring consistent clarity and glare reduction
- Reliable Stability & Longevity: Withstands 10,000+ temperature cycles and operates stably in -40°C to 85°C environments
- Wide Applicability & Custom Flexibility: Available in thickness options from 0.38mm to 1.52mm with customizable color transition points
Application Scenarios
- Building Energy Efficiency: Curtain walls, skylights, windows, and doors for offices, hotels, and residential buildings
- Automotive Comfort & Efficiency: Car windows and sunroofs for improved temperature control and 5%-10% better fuel efficiency
- Industrial Equipment Monitoring: Machinery, pipelines, power plants, and data centers for proactive temperature monitoring
