    Abstract: An endothermic fireproof cladding material for electric cables, a cross-sectional structure of which is a two-layer or three-layer laminated composite structure in an integrated structure by coating, and one of the laminated structures has a fireproof fiber mesh cloth having a thickness of 0.03 mm to 0.24 mm as a coating and coating substrate. The fireproof fiber mesh cloth is selected from one of a glass fiber, a carbon fiber, a polyacrylonitrile (PAN) oxidized fiber, a ceramic fiber, a water-soluble alkaline earth fiber and an aromatic polyamide fiber.

    Abstract: An infrared shielding film and a method for manufacturing the same are provided. The infrared shielding film includes an infrared absorbing layer and a first infrared reflecting layer disposed on a surface of the infrared absorbing layer. The infrared absorbing layer contains a uniform distribution of composite tungsten oxide particles that are present in an amount of 0.1% to 10% by weight based on the total weight of the infrared absorbing layer. The first infrared reflecting layer contains a uniform distribution of titanium oxide particles that are present in an amount of 0.1% to 10% by weight based on the total weight of the first infrared reflecting layer.
