Product Overview
The PDLC (Polymer Dispersed Liquid Crystal) dimming film produced and sold by our company, westglass, is a high-tech thin-film material leveraging liquid crystal technology. It enables intelligent adjustment of light transmittance via current control, formed by embedding liquid crystal molecules between two layers of transparent conductive films. When unpowered, the liquid crystal polymers arrange randomly, blocking most parallel light and appearing opaque and milky; when powered, an electric current aligns the polymers uniformly, allowing light to pass through clearly for a transparent state. Its core function—"one-touch switching between transparent and frosted states"—combines privacy protection, energy efficiency, and spatial aesthetic design, making it ideal for architectural curtain walls, residential partitions, automotive glass, and commercial displays.
With 8 years of production and sales experience, westglass offers customized electrode-equipped sheets (simply provide your window dimensions), roll materials (30m×1.52m/60m×1.52m/100m×1.52m), and laser-cut special-shaped sheets to meet diverse project needs.
Core Features
• Intelligent Dimming
Supports manual, remote, and smart central control, enabling instant switching between transparent (light transmittance: 83% / 86% / 89% / 91%) and frosted (light transmittance < 5%) states to balance privacy and natural light requirements.
• Energy Efficiency & UV Protection
The frosted state blocks over 99% of UV rays, reducing air conditioning loads, extending the lifespan of indoor furnishings, and complying with green building standards.
• Ultra-Thin & Flexible Design
With a thickness of just 0.3–1.1mm, it adheres seamlessly to curved glass and complex architectural structures without occupying extra space.
• Safety & Longevity
Uses a laminated structure for high impact resistance, ensuring glass fragments stay bonded if broken. Operates at a low voltage (24–48V) with no electromagnetic radiation risk, supporting over 100,000 switching cycles for long-term reliability.
Typical Applications
• Commercial Offices: Glass partitions for conference rooms, integrated projection screen solutions;
• Residential Spaces: Bathroom doors/windows, smart dimming curtain walls in living rooms;
• Transportation: Car sunroofs, airplane window privacy adjustment;
• Innovative Displays: Transparent advertising windows, AR interactive screens.
Installation & Care Instructions
• Professional installation is required to ensure a clean, dust-free glass surface for optimal adhesion.
• Avoid scratches from sharp objects; clean gently with a soft cloth for routine maintenance.
• Defaults to the frosted state when unpowered to maintain privacy as a safety feature.
• Installation Prohibited In: Dirty work environments or non-compliant glass (e.g., outdoor-only glass, unclean surfaces, visible scratches, protrusions, or irregular shapes).
