Super insulation cotton is a cross-linked sheet-like insulation material made of polymer bone material and nanoporous vacuum silica. The nanoporous vacuum silica has a pore size of 10-40 nm, which is smaller than the average free path of air molecules at 68 nm. It has a porosity of 979 or higher and a density as low as 0.03g/ml or below, achieving a vacuum like effect. Therefore, there will be no collisions between molecules inside the pores, thus achieving ultra-high insulation performance. MFG super insulation cotton is a cross-linked sheet-like insulation material made of polymer bone material and nano porous vacuum silica. Nano porous vacuum silicon? The pore size is 10-40 nm, which is smaller than the average free path of air molecules at 68 nm. It has a porosity of over 97% and a density as low as below 0.03 g/ml, achieving a vacuum like effect. The high thermal insulation performance is achieved by preventing collisions between molecules inside the pores. Meixing MGF insulation cotton is a flexible sheet insulation material made by combining porous oxidized vacuum stone material with polymer skeleton material through vacuum cross-linking gasification high-pressure drying preparation process. MGF insulation cotton has a 3-hole structure, uniform surface, and the lowest thermal conductivity coefficient, which can achieve the insulation problem of products in narrow spaces. At the same time, it further enhances the comfort of human experience. Compared with traditional insulation materials, MGF insulation cotton further reduces 0.014W/m · K, and has excellent properties such as hydrophobicity, flame retardancy, insulation, and environmental protection. It solves the problem of low thermal conductivity and is very suitable for use in electronic products such as aerospace, smart hand terminals, smart wearables, electronic cigarettes, wireless chargers, power supplies, small appliances, and large equipment insulation.
