Product Overview
The Westglass Thermochromic Sunshade PVB Materials Laminated Film
Series is engineered for smart architectural and automotive glass,
using an 80% polyvinyl butyral (PVB) resin base combined with 20%
photothermal nanomaterials. Triggered by temperature changes with a
25°C baseline, it enables stepless adjustment of color and light
transmittance (smart switching between clear and blue/gray states),
while delivering three core benefits: impact resistance, ≥30dB
noise reduction, and 30% HVAC energy savings. Ideal for curtain
walls, car sunroofs, and industrial monitoring, it comes with a
10-year warranty, offering a fully integrated solution for safe,
energy-efficient, and intelligent glazing.

- Global Logistics: Non-custom orders ship in 1–3 days; custom orders ready in 15–30
days with end-to-end tracking.
Core Advantages
1. Intelligent Thermal Regulation
- 25°C Baseline Stepless Dimming:
- Warm Conditions (>25°C): Instantly darkens to ≤30% transmittance, reflecting 80% of
infrared rays and lowering indoor/cabin temperature by 5–8°C.
- Cool Conditions (<25°C): Restores to ≥80% transmittance for unobstructed natural light—no
energy or manual adjustment needed.
- Zero-Energy Operation: Self-powered by ambient temperature changes for sustainable,
hassle-free performance.
2. Safety & Health Protection
- Explosion-Proof Impact Resistance:
- PVB substrate with tensile strength >20MPa keeps 99%+ of
shattered glass fragments bonded, eliminating splash risks.
- 99% UV Blocking: Shields luxury furniture, automotive leather interiors, and
artworks, reducing fading/aging risks by 90%.
3. Long-Lasting Durability
- Extreme Environment Resilience:
- Operates stably in -40°C–85°C, resisting brittleness in arctic cold
and delamination in tropical heat—ideal for deserts, polar regions,
and coastal areas.
- Decade-Long Lifespan: Matches vehicle design cycles (10 years) and lasts 10+ years in
buildings—significantly longer than standard sunshade films,
cutting replacement costs.
4. Optical Excellence
- Crystal-Clear Vision:
- Low haze in clear state ensures distortion-free views for safe driving at night and bright,
natural lighting in buildings.
- Aesthetic Flexibility:
- Customizable in cool blue, warm yellow, and other tones to
complement modern minimalist or industrial design aesthetics.
5. Premium Noise Reduction
- 30dB Noise Blocking: Dampens mid-low frequency sounds (traffic, machinery), creating
quieter conference rooms, driver cockpits, and living spaces.
Application Scenarios & User Value
1. Architecture
- Smart Curtain Walls: Dynamic dimming + 40% energy savings for reduced building
operational costs.
- Sunrooms/Greenhouses: Auto-adjusts light intensity to optimize plant growth while
maintaining comfortable temperatures.
2. Automotive
- EV Sunroofs: Darkens in strong sunlight to reduce battery heat load, extending
electric range.
- Commercial Vehicle Side Windows: 30% transmittance blue tint for privacy + full UV protection,
ideal for luxury MPVs.
3. Industrial Monitoring
- Power Equipment Windows: Instant temperature anomaly alerts via color changes, preventing
overheating accidents and lowering maintenance costs.
- Petrochemical Pipeline Covers: Corrosion-resistant coating + thermal indication for enhanced
safety in high-risk environments.
