Bat-wing Optical Diffusion Film
Core PC Base Material
Impact Resistance: Unaffected by drops, collisions, or harsh handling-critical for automotive, aerospace, and outdoor applications (e.g., road signage in the UK, where vandalism or weather-related impacts are common).
Thermal Stability: Maintains performance across -40°C (Nordic winters) to 120°C (Mediterranean summers), with no warping, cracking, or loss of reflectivity.
Architectural & Commercial Lighting
Office Ceiling Panels: Used in Berlin's new Siemens headquarters, PET-based Bat-wing Optical Diffusion Film delivers 160° coverage-illuminating 100m² office floors with just 8 LED panels (vs. 12 panels with generic films). This cuts energy consumption by 25% while meeting EN 12464-1's uniformity standards, reducing employee eye strain complaints by 40% (per internal surveys).
Compliance with European Regulations
REACH Regulation (EC 1907/2006): All components (PC resin, reflective coatings, additives) are free from Substances of Very High Concern (SVHCs) above 0.1%, with complete Safety Data Sheets (SDS) and SVHC screening reports available for every shipment.
RoHS Directive (2011/65/EU): No lead, cadmium, mercury, or hexavalent chromium-ensuring compatibility with electronic products (e.g., LED displays, medical devices) sold in the EU.
EN 62471 (Photobiological Safety): Tested and certified by TÜV SÜD to meet Risk Group 1 for blue light safety-critical for indoor lighting and displays used in homes, offices, and schools (e.g., preventing eye strain in German classrooms).
Low VOC Emissions: Compliant with EU ISO 16000-6 standards for indoor air quality, making it safe for enclosed spaces like hospitals and offices (a key requirement for clients in Austria and Switzerland).
Weather & UV Resistance
UV Stability: A co-extruded UV-resistant layer (containing hindered amine light stabilizers, HALS) prevents yellowing, cracking, or loss of reflectivity after 5,000+ hours of accelerated weathering (equivalent to 10+ years outdoors in Spain or Greece).
Moisture Resistance: Unaffected by 90% relative humidity at 60°C (tested per EN ISO 6287), making it suitable for bathrooms, swimming pools, and coastal projects.
Museum & Gallery Lighting: For the Rijksmuseum (Amsterdam) or Vatican Museums (Rome), PMMA-based Bat-wing Optical Diffusion Film provides 180° coverage-illuminating large artifact halls (e.g., 200m² Renaissance galleries) without hotspots or glare. This protects delicate artifacts from harsh light while ensuring visitors can view details clearly (compliant with EN 15740, EU conservation standards).
