Dimming Glass

Dimming glass from Qingdao Pioneer Glass is a laminated electrochromic product composed of two layers of tempered glass with a liquid crystal film interlayer bonded under high temperature and pressure. The glass operates at 24 VAC, 48 VAC, or 65 VAC, achieving 75% light transmittance when powered and switching to an opaque state when de-energized. The total thickness ranges from 5.5 mm to 40.5 mm, with a 1.5 mm interlayer, and supports custom cutting and drilling for architectural integration.

The product complies with China standard JC/T2129-2012 and meets safety glass requirements, including impact resistance and shatter containment. The liquid crystal layer provides privacy at a distance of 3 cm from either side, effectively blocking visual clarity without the need for blinds or curtains. It also functions as a projection surface, supporting high-definition imagery when powered, making it suitable for conference rooms, retail displays, and residential partitions. The average energy consumption is approximately 5 watts per hour per square meter, with a rated operational life exceeding 10 years under normal conditions.

This glass is primarily purchased by architectural firms, hotel developers, and commercial interior designers seeking smart privacy solutions. Buyers typically order custom sizes and shapes for installations in offices, hospitals, and luxury homes. Packaging is done in wooden crates with edge protectors, and shipping is handled under FOB Qingdao terms. Lead times vary based on customization, and buyers should confirm exact dimensions and voltage requirements before production.
