Product Overview
The Smart Film (PDLC Film/Polymer Dispersed Liquid Crystal Dimming Film) Series from Westglass is a high-tech optical film leveraging the electric field response of liquid crystal molecules. By hermetically encapsulating liquid crystal polymer between two transparent conductive films, it forms a unique laminated structure for intelligent electric control of light transmittance:
l Unpowered State:
Liquid crystal molecules arrange randomly, creating a light-scattering layer with transmittance below 5%. This uniform milky frosted effect ensures robust privacy protection.
l Powered State:
Driven by a safe voltage, molecules align orderly within 0.2 seconds, achieving up to 91% transmittance to restore natural glass clarity.
Why Choose Westglass?
As a PDLC specialist with 8 years of industry experience, Westglass offers three standardized product solutions:
1. Custom Electrode Sheets:
Tailored to your window dimensions for precise fit.
2. Special Customization:
Laser-cut for irregular/curved/hollow glass shapes, adapting to unique architectural designs.
3. Standard Rolls:
Available in 15m/30m/60m/100m lengths (1.52m width), ideal for large-scale projects.
4. Rigorous Quality Control:
Three-layer inspection system: 100% roll material testing, oven durability checks, and sheet power-aging trials.
5. Rapid Global Delivery:
l Standard rolls: Shipped within 24 hours.
l Custom orders: Laser-cut (supports irregular/curved/hollow designs) and dispatched within 72 hours.
Core Features
1. Intelligent Dimming System
l Flexible Control: Switch freely via physical switches, wireless remotes, or smart central systems.
l Transmittance Gradient: Four preset options (83%/86%/89%/91% in transparent state; <5% in frosted state).
l Millisecond Response: State switching completes in ≤0.2 seconds.
2. Energy Efficiency & Environmental Safety
l 99% UV Blocking: Reduces heat radiation and furniture aging, meeting international standards.
l Infrared Insulation: Cuts air conditioning energy use by 30%.
l RoHS Certified: Compliant with global environmental safety regulations.
3. Ultra-Thin Flexible Design
l Curved Glass Compatibility: Seamless adhesion with flatness error <0.02mm/m².
l Extreme Environment Resistance: Operates at -30°C to +80°C and 20%-95% humidity.
4. Enhanced Safety & Explosion Resistance
l 3x higher impact resistance than standard glass.
l Fragment adhesion ≥98%, exceeding national safety glass standards.
Typical Applications
1. Commercial & Office
l Smart Conference Room Partitions: One-touch switching between private meeting and open space modes.
l Projection-Integrated Curtain Walls: Frosted state transforms into a HD projection screen with 40% sharper resolution.
2. Residential
l Bathroom Privacy Windows: Moisture-resistant design operates stably in >90% humidity.
l Living Room Dimming Walls: Syncs with smart home systems to auto-adjust indoor lighting.
3. Transportation
l Automotive Panoramic Sunroofs: UV protection + zoned dimming with multi-level transmittance.
l Airplane Window Upgrades: Automatic frosting during takeoff/landing to reduce glare discomfort.
4. Innovative Displays
l Transparent Advertising Windows: Showcases products clearly by day, plays HD videos frosted by night.
l AR Interactive Screens (with optional touch accessories): Capacitive touch support with ≤8ms response.
Usage Notes
1. Privacy Safety:
Maintains frosted state when unpowered to ensure privacy during outages.
2. Quality Assurance:
All products pass 72-hour continuous aging tests and come with a 2-year warranty.
Installation Guidelines
1. Professional Installation:
Must be handled by certified technicians; glass flatness checked via laser scanner (error ≤1.5mm/m²).
2. Environmental Requirements:
15–35°C temperature, 40%–70% humidity.
Prohibited Scenarios
1. Strong acid/alkali environments (pH <3 or >11).
2. High-frequency vibration areas (amplitude >2mm or frequency >50Hz).
3. Non-planar glass substrates (curvature radius <150mm).
