Ultrafine Bubble Light Reflective Sheet 'MCPET / MCPOLYCA'

- In the era of high-speed communication and IoT, a large number of antenna devices and sensors are introduced, which can impair the urban landscape. - By utilizing ultra-fine foamed resin (MCP) with excellent radio wave permeability, light reflectivity, and light diffusion as a reflective plate for lighting, and placing a wireless substrate behind it, we can develop lighting that integrates antennas and sensors, thereby improving the urban landscape. 【Features of Ultra-Fine Foamed Resin Material (MCP)】 1. By foaming low dielectric resin materials, the material's relative permittivity (Dk) and dielectric loss tangent (Df) decrease, leading to further improvement in radio wave permeability. In particular, our proprietary ultra-fine foamed resin (MCP) can form bubbles in the micron size range, achieving good radio wave permeability even for high-frequency waves. 2. Foaming reduces the material density, resulting in lightweight materials. 3. In foamed resin materials, light is reflected at the interface between the resin and the bubbles. Especially with our proprietary ultra-fine foamed resin (MCP), by making the bubble diameter fine, light reflection is repeated near the material surface, suppressing light transmission into the material and demonstrating excellent light reflectivity. It shows high reflectivity not only in the visible light range but also in the infrared range. 4. Ultra-fine foamed resin (MCP) has excellent processability, allowing for molding and cutting from sheet shapes.

In 5G/6G, the introduction of a large number of communication devices that handle high-frequency radio waves will lead to issues such as securing installation locations for communication devices, increased power consumption, and increased heat generation from antenna substrates. By utilizing our unique ultra-fine foamed resin material (MCP), we can expect an extension of the installation intervals for communication devices, improved flexibility in installation locations due to weight reduction, reduced power consumption, and enhanced freedom in thermal design of the equipment. 【Features of Ultra-Fine Foamed Resin (MCP)】 1.
