Enclosure

Product Description

‌Low-E conductive glass (Low-emissivity conductive glass)‌ is a specialized glass that combines optical transparency with electromagnetic shielding functionality for shielded enclosures. It achieves Low emissivity (E-value ≤ 0.15) and conductivity by coating metal oxides or silver-based films, while meeting the shielding effectiveness requirements of the Electromagnetic Shielding Glass standard for the 30MHz–1GHz frequency range.‌

Application

‌•‌Radar Enclosures & Command Shelter Viewports‌

Must meet ‌high shielding effectiveness (≥80dB)‌ and ‌explosion-proof requirements‌.

•‌‌5G Base Stations & Server Shielding Enclosures‌

Utilize ‌laminated composite structures‌ to balance ‌transparency and protection‌.

•‌‌MRI Shielding Room Viewports‌

Require ‌non-metallic interference-free‌ design while maintaining ‌optical clarity‌.

Product details

Benefits

1. ‌Electromagnetic Shielding Performance‌

Shielding effectiveness ≥60dB (1GHz high-frequency band)‌, with laminated structures capable of reaching ‌≥80dB‌.

Conductive film layers (e.g., ITO or silver-based)‌ provide electrostatic dissipation paths, preventing charge buildup and device interference.

2. ‌Optical & Thermal Performance‌

Visible light transmittance: 50%~80%‌, ‌infrared reflectivity ≥90%‌, suitable for enclosure viewports.

Emissivity (E-value) ≤0.15‌, reflecting indoor thermal radiation in winter and blocking external heat in summer.

3. ‌Environmental Adaptability‌

Operating temperature: -45℃~+60℃‌, with vibration resistance meeting military standards.

Chemical corrosion resistance‌, suitable for high-humidity or salt-mist environments.‌

Working Principle

1‌.Electromagnetic Shielding Mechanism‌

The ‌metal film layers‌ (e.g., silver, copper) attenuate electromagnetic waves through ‌reflection and absorption‌, while ‌laminated structures‌ (e.g., metal mesh + Low-E film) enhance shielding effectiveness.

When the ‌conductive film layer is grounded‌, it forms a ‌Faraday cage effect‌, blocking high-frequency interference.

2.‌Thermal Radiation Regulation‌

The ‌Low-E film layer‌ reflects ‌far-infrared radiation‌ (wavelength: 4.5–25 μm), reducing heat exchange.

The ‌silver-based film layer‌ reflects ‌over 98% of infrared radiation‌, similar to a mirror effect.‌
