Product Overview

The dimming film produced and sold by our company, westglass, is a new-generation electro-optical product designed for effortless use. Simply apply it to glass surfaces to enable the effect of "transparent when powered, frosted when unpowered." The technology leverages the optical properties of liquid crystals: a liquid crystal polymer mixture is sandwiched between two transparent conductive films. Without an electric field, the polymer molecules are randomly arranged, making the film opaque; when powered, an electromagnetic field aligns the molecules uniformly, achieving a transparent state.

With 8 years of production and sales experience, westglass offers customized electrode-equipped sheets (provide your window dimensions), roll materials (30m×1.52m/60m×1.52m/100m×1.52m), and laser-cut special-shaped sheets to meet diverse needs.

Core Functions & Advantages

1. One-Touch Transparent/Frosted Switching

•        Instantly switch between transparent and frosted (matte) states via voltage control. The film appears milky and opaque when unpowered, and highly transparent with ordered molecular alignment when powered.

•        Supports grayscale adjustment to adapt to different lighting environments.

2. Privacy Protection & Space Optimization

•        Replaces traditional curtains or blinds as an "electronic curtain" for instant privacy shielding.

•        Ideal for residential bathrooms, bedroom partitions, offices, conference rooms, and other spaces requiring discrete visual control.

3. High Compatibility & Easy Installation

•        Directly adheres to tempered glass surfaces with no adhesive residue, ensuring hassle-free installation.

•        Available in two forms: laminated (PVB/EVA composite technology) and self-adhesive, catering to customized requirements.

•        Offers four transmittance options when powered: 83% / 86% / 89% / 91%.

Product Highlights

1. Energy Efficiency & Sustainability

•        Low power consumption of only 4–5W per square meter. Blocks harmful UV and infrared rays, reducing building energy costs and carbon footprint.

2. Enhanced Projection Capability

•        Functions as a high-definition projection screen in the unpowered state, supporting double-sided viewing—perfect for commercial displays and home theaters.

3. Superior Safety Protection

•        Impact-resistant and explosion-proof design prevents glass shattering and splashing upon impact, offering higher safety than standard glass.

4. Long Lifespan

•        Constructed with high-molecular liquid crystal materials and stable encapsulation technology, ensuring excellent durability and resistance to aging.

Typical Applications

1. Architecture

•        Smart windows, partition curtain walls, hotel bathrooms—balancing privacy and natural light.

2. Commercial Spaces

•        Mall storefronts, exhibition projection screens, conference room privacy glass—enhancing technological appeal and functionality.

3. Automotive

•        Window and rearview mirror dimming for sunshade and anti-glare effects.

4. Medical Field

•        Hospital ward observation windows, operating room partitions—safeguarding privacy and sterile environments.
