Product Definition
The innovative Westglass PNLC Film Series (Reverse Smart Dimming Film) employs revolutionary electro-optical technology with a reverse logic compared to conventional PDLC films: it stays optically transparent when power off and instantly activates a frosted state when power on. By precisely stacking flexible ITO conductive layers, polymer-dispersed liquid crystal (PDLC) layers, and impact-resistant PET substrates, it uses electric fields to control liquid crystal molecular orientation for instantaneous state switching. With self-adhesive installation, it directly applies to existing glass surfaces for smart upgrades, serving applications like architectural curtain walls, medical cleanrooms, and smart homes.
Why Westglass?
As an 8-year veteran in smart films, Westglass offers:
- Custom Electrode Sheets: Tailored to window dimensions with integrated electrodes.
- Roll Materials: Standard rolls (1.2/1.45m×30/50m) for large-scale projects.
- Custom Shapes: Laser-cut with ±0.5mm precision for circles, polygons, and other special contours.
- Rigorous Quality Control: Enforces a three-layer standard: 100% roll inspection → oven baking tests → sheet power aging verification.
- Expedited Fulfillment: Standard rolls ship within 24 hours; custom orders ready in 3 business days.
Core Value Proposition
1. Intelligent Privacy Management
- Reverse Light Control: Zero-energy transparent default mode; power on triggers ≥90% haze for privacy—ideal for commercial windows and open offices needing both display and sudden privacy.
- Instant Response: Transitions from clear to fully frosted in milliseconds.
2. Protective Performance Matrix
- Safety & Explosion-Proof: Holds >95% of shattered glass fragments upon impact.
- Energy Efficiency: Only consumes power when privacy is needed, reducing overall energy use by 50%+ vs. traditional PDLC films.
- UV/IR Protection: Blocks 99% UV and ≥60% IR, slowing furniture aging.
- Digital Interaction:
- Projection-Ready: Frosted surface acts as a uniform projection screen for digital signage and immersive exhibitions.
- Multi-Channel Control: Supports remote, voice, app, and smart home system integration.
3. Universal Adaptability
- Easy Installation: Self-adhesive design fits all glass surfaces, up to 1.5m width, with no structural removal—cost-effective renovation.
- DIY-Friendly: No professional tools needed; upgrade old glass in 1 hour.
