Product Introduction
Rina Technology Co., Ltd. is one of the leading manufacturers and suppliers of dimming optical film in China. Welcome to wholesale durable products in stock here and get quotation from our factory. All customized products are with high quality and low price.
Key characteristics that define our Dimming Optical Film include:
Dual-mode dimming: Available in "transparent-opaque" (privacy mode) and "gradual dimming" (light adjustment) options-ideal for European clients needing both privacy (e.g., hotel rooms) and glare reduction (e.g., office lobbies).
Fast response time: Adjusts from fully transparent to opaque in <0.5 seconds (vs. 2-3 seconds for cheap films), ensuring real-time control for high-traffic areas like airport security checkpoints.
Energy efficiency: Reduces solar heat gain by 60-70% in opaque mode, cutting cooling costs by 30-40% (critical for Southern European countries like Spain and Italy) and retains heat in transparent mode, lowering heating bills in Northern Europe.
European compliance: Every batch of Dimming Optical Film meets CE (EN 61558 for electrical safety), RoHS (restricts 10 harmful substances), and REACH (complies with 235 SVHC substances) standards-eliminating regulatory risks for European clients, whether for building projects or consumer products.
Base Substrate: High-Grade PET or PC
PET (Polyethylene Terephthalate) substrate: Ideal for indoor and mild outdoor use (e.g., office partitions, retail display cases). It offers exceptional dimensional stability (thermal expansion coefficient: 7×10⁻⁵/°C), ensuring the film does not warp or shrink in Europe's temperature-fluctuating environments (e.g., heated conference rooms in winter, air-conditioned malls in summer). It's also lightweight (density: 1.38g/cm³) and easy to install, reducing labor costs for project clients.
PC (Polycarbonate) substrate: Designed for heavy-duty outdoor or high-impact use (e.g., automotive sunroofs, public transport windows, stadium facades). It boasts superior impact resistance (notched Izod impact strength: 60kJ/m²), making it resistant to hail (common in Northern Europe) or accidental collisions (critical for train windows in busy cities like Paris or Berlin). It also withstands extreme temperatures (-40°C to 120°C), ensuring stability in Scandinavian winters (-25°C) and Mediterranean summers (40°C+).
Both substrates are sourced from top global suppliers (e.g., DuPont, Sabic) and undergo rigorous purity testing-avoiding defects like uneven thickness or impurities that plague low-cost substrates.
Energy savings: A Frankfurt-based construction firm installed Dimming Optical Film on 8,000 square meters of glass in a new office tower. The film reduced cooling costs by 35% in summer and heating costs by 20% in winter, helping the building achieve BREEAM "Excellent" certification.
Space flexibility: For open-plan offices, the film's privacy mode (opaque) transforms glass partitions into temporary meeting rooms-no need for permanent walls. A London tech firm used 2,000 square meters of film, increasing usable office space by 15%.
Glare reduction: In Barcelona's sunny climate, the film's gradual dimming mode eliminates screen glare for 300+ employees, reducing eye fatigue complaints by 40%.
30 advanced production lines: Each line produces up to 15,000 square meters of Dimming Optical Film daily, with a total monthly capacity of 10 million square meters. This means we can fulfill even the largest European projects-for example, a Madrid construction firm ordered 50,000 square meters of film for a smart mall, and we completed production in 3 days.
Raw material stockpiles: We maintain 2,000+ tons of PET/PC substrates, 500+ kg of high-purity liquid crystals, and 100+ tons of ITO coatings in stock. This eliminates material shortages (a common issue for small factories) and ensures we can start production immediately after receiving an order. During Europe's peak construction season (spring/summer), we never face delays due to stockouts.
24/7 operation: For urgent orders (e.g., a cruise line needing film before a new ship launch), we run production lines around the clock. A Mediterranean cruise operator ordered 8,000 square meters of Dimming Optical Film with a 7-day deadline-we operated 24/7 and delivered 1 day early.
"Does Dimming Optical Film Meet European Electrical & Safety Standards?"
CE certification: Our film meets EN 61558 (electrical safety), EN 12600 (impact resistance), and EN ISO 10993-1 (biocompatibility for medical use). We provide a CE certificate with every order-critical for project approval (e.g., a Berlin hospital used our certificate to pass local health authority inspections).
RoHS compliance: We test every batch for lead, mercury, and 8 other restricted substances. Our RoHS reports are recognized by European customs and retailers (e.g., Amazon EU).
"What If the Film Fails or Malfunctions? How Do You Handle Warranties?"
10-year warranty: We offer a 10-year warranty on Dimming Optical Film-covering defects like slow response time, LC leakage, or ITO failure. If the film malfunctions within 10 years, we replace it for free-including shipping from China to Europe.
Pre-shipment inspection (PSI): Clients can request a PSI-we send photos/videos of the film's performance, or arrange a third-party inspector (SGS/BV) to visit our factory and test dimming function.
Pain Point 1: High Costs of Local European Products
Factory-direct pricing: No distributors or middlemen-we sell directly to European clients. A Berlin construction firm saved €100,000 by buying 50,000 square meters from us vs. a local supplier.
Bulk discounts: For orders over 10,000 square meters, we offer 8-15% discounts. A Madrid retail chain saved €25,000 on their 20,000-square-meter order.
Pain Point 2: Long Lead Times for Custom Orders
Dedicated custom lines: 10 production lines focus solely on custom orders, ensuring speed.
In-house integration: We handle all customization steps (cutting, coating, testing) in-house-no outsourcing, no delays.

FAQ
01.The Dimming Optical Film fails to switch states properly.
Cause Analysis: The power may be disconnected, the power controller may be faulty, the wiring may be loose, or the switchable film may be damaged.
Solution: Check that the power switch is on and the power circuit is functioning properly. Check that the power controller indicator is on. If there is a problem, replace it immediately. Recheck the wiring to ensure it is securely connected. If the switchable film is damaged, contact a professional for replacement.
02.Bubbles or wrinkles appear on the Dimming Optical Film surface.
Cause Analysis: Uneven application of glue during installation, failure to completely expel air during film application, or improper operation.
Solution: For small bubbles, puncture them with a needle and then use a scraper to squeeze out the air. For larger bubbles or wrinkles, reapply the film, ensuring that the glue is evenly applied and that all air is completely expelled during installation.
03.The Dimming Optical Film transparency has decreased or the atomization effect is poor.
Cause Analysis: The switchable film surface is dirty, aged, or corroded by chemicals. Solution: Clean the surface of the switchable film with a clean, soft cloth and neutral detergent. If the switchable film is aged or damaged, replace it promptly. Avoid contact with acidic or alkaline chemicals to prevent corrosion.
