Product Description
Product Overview
Westglass Thermochromic Sunshade PVB Film Series is a dry-process laminated glass interlayer composed of 80% polyvinyl butyral (PVB) resin powder and 20% photothermal polymer nanomaterials. Using 25°C as baseline, the film's color adjusts reversibly between clear and colored states in response to ambient temperature changes without external power. This intelligent switching dynamically controls light and heat transmission while maintaining strong adhesion and safety features.
Key Advantages
Intelligent Thermal Control & Energy Efficiency
- Dynamic light regulation: Darkens to ≤30% transmittance at high temperatures, blocking 80%+ infrared rays
- Reduces indoor temperature by 3-8°C and AC energy use by 30%-50%
- Wide temperature adaptation: Responds to -20°C to 80°C range
Safety & Protection Features
- 99%+ UV blocking protects interiors from fading
- 85%+ infrared blocking reduces solar heat gain
- Anti-glare design enhances safety and comfort
- Impact resistance bonds shattered glass fragments
Durability & Performance
- Withstands -40°C to 85°C thermal cycles
- 10+ years of stable performance
- High-transparency state with haze ≤1%
