Product Specification

Product Overview

The Westglass Photochromic Film Series is an innovative functional film leveraging photochromic material technology. At its core are intelligent light-sensitive molecules that dynamically adjust light transmittance and color without external power, responding to UV intensity changes: darkening rapidly in strong sunlight to block glare and restoring high clarity in low light.

Using advanced photochromic technology, it solves visual discomfort like excessive brightness and glare while integrating functions such as heat insulation, UV protection, and energy savings. Ideal for applications like architectural windows and automotive glass, it sets a new standard for adaptive light management.

Why Choose Westglass?

1.     Technological Leadership

• Specializing in single-silver and dual-silver photochromic films, we hold patents for our blue-series GD Series and offer custom black-series VB Series and pure ceramic photochromic films to meet diverse scenario needs—from commercial buildings to automotive and marine use.

2.     Industry-Leading Performance

• Ultra-Wide Transmittance Range: Adjusts visible light transmittance across 75%–20% (15%–80% for custom models), far exceeding industry averages for seamless adaptation to all-day lighting changes.
• Long-Lasting Stability: Passes rigorous weather resistance testing, maintaining stable color-changing performance for 5+ years with leading anti-yellowing and anti-degradation capabilities.

3.     Fully Customizable Solutions

• Branding & Sizing: Custom packaging, logo printing, and standard rolls (30m/60m *1.52m) to meet unique branding and installation requirements.
• Technical Parameter Tailoring: Customize transmittance, thickness (0.4mm–1.52mm), and composite structure for adhesive films, dual-triple silver variants, or pure nano-ceramic solutions—perfect for OEM/ODM partnerships.

Core Advantages

1.     Stepless Dynamic Dimming

• Auto-Responsive Light Control:
  • No manual adjustment or power needed. Light-sensitive materials sense ambient light in real time, darkening to block glare in strong sunlight and clearing to maintain soft, natural light in low conditions—creating all-weather visual comfort.

2.     Premium Visual Experience

• Distortion-Free Clarity:
  • Haze <1% in all states, ensuring unobstructed views with no scattering, distortion, or blur for natural light and scenic vistas.
• True Color Fidelity:
  • Nano-level material formulation keeps color coordinate shifts <3%, preserving object original colors and avoiding the color deviation common in traditional dimming films.

3.     Dual Light-Heat Blocking

• High-Efficiency Thermal Insulation:
  • ≥80% infrared blocking (≥90% for select models), reducing indoor heat load by 3–5°C in summer and cutting AC runtime for 30%+ energy savings.
• Full-Spectrum UV Protection:
  • ≥99% UV blocking shields UVA/UVB rays, protecting furniture, floors, and fabrics from fading and aging.

4.     Zero-Energy Green Operation

• Driven solely by natural light—no electricity or complex systems required, aligning with sustainable, low-carbon goals.

5.     Lightweight & Efficient Installation

• Self-Adhesive Design:
  • Low-tack pressure-sensitive adhesive applies directly to glass, supporting dry/wet installation on flat/curved surfaces (e.g., car sunroofs, arched) with 60% faster installation and 50% lower retrofit costs than traditional dimmable glass.
• Custom Sizing:
  • Standard 1.52m width with customizable length; supports irregular glass cutting (contact customer service for tailored solutions).

6.     Customizable Aesthetics

• Available in gray, blue, tan, and other custom tints to balance architectural beauty and privacy needs.

7.     Safety Reinforcement

• Explosion-Proof & Impact-Resistant:
  • 3mil+ thickness (multi-layer options) bonds shattered glass fragments, delaying breakage and reducing splash risks—certified to GB/T 2680 for high-safety applications like skyscraper windows and car sunroofs.

8.     Extreme Environment Resistance

• Wide Temperature Range: Operates stably in -40°C–85°C, resisting high humidity (95% RH) and salt spray for reliable performance in polar and tropical climates.
• Longevity Assurance: Passes 5,000+ color cycles with no degradation or delamination, backed by a 5-year warranty (10-year for select models).

9.     Eco-Friendly & Safe

• Zero formaldehyde, VOC-free materials with no pungent odors—ideal for homes, hospitals, and other air-quality-sensitive environments.

10.  Dynamic Privacy Protection

• Dark or custom-tinted films auto-darken in strong light to obscure views while maintaining translucency, perfect for commercial storefronts, office partitions, and residential spaces.

Application Scenarios

1.     Architecture

• Offices & Commercial Spaces:
  • Curtain walls, skylights, and windows replace traditional blinds for adaptive light control and energy savings; storefronts and display cases achieve dynamic visual appeal.
• Luxury Residences:
  • Floor-to-ceiling windows and skylights balance natural light and privacy, reducing glare for comfortable living spaces.
• Healthcare Facilities:
  • Hospital rooms and labs benefit from UV protection for equipment/drugs and 15–20dB noise reduction for quiet, safe environments.

2.     Automotive

• Windshields/Side Windows:
  • Reduces driver eye strain from sudden light changes (e.g., tunnels to sunlight) and improves energy efficiency for EVs by lowering AC load.
• Car Sunroofs:
  • Auto-dimming in strong sunlight blocks UV rays and heat, keeping interiors cool and comfortable.
