In today’s high-tech manufacturing landscape, the demand for light-insensitive electronic components is skyrocketing. From autonomous vehicle sensors to medical imaging devices, even a fraction of light exposure can render products unusable. If your current PE black-white film fails to meet light-blocking standards, discover how Guangdayuan’s 20+ years of innovation delivers unmatched performance.
The 3-Layer Advantage: Designing for Optimal Opacity
Guangdayuan’s proprietary structure addresses common light leakage flaws:
1、Black Barrier Layer: 30%+ carbon black concentration (imported from Germany) creates a dense light-absorbing matrix.
2、PE Core Layer: Impact-resistant polymer blend prevents micro-cracking that can cause light seepage.
3、White Reflective Layer: Titanium dioxide-enhanced surface bounces back any stray light, doubling effective opacity.
Technical Specifications That Matter
Visible light transmittance: <0.1% (measured at 400-700nm)
UV transmittance: <0.05% (200-400nm)
Tensile strength: 28MPa (longitudinal), 25MPa (transverse)
Elongation at break: ≥300%
How to Select the Right Film for Your Electronics
Not all light-blocking needs are the same. Guangdayuan’s application guide helps you choose:
For LCD Panels: 0.05mm film with anti-glare white surface
For Semiconductor Wafers: 0.1mm static-free black-white film
For Optical Fibers: 0.03mm ultra-thin variant with low shrinkage
Beyond Electronics: Diverse Light Protection Applications
