Product Specification

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.
