Flame retardant casing, also known as fireproof casing or thermal insulation casing, is a material with excellent flame retardant and thermal insulation properties. It is usually made of high-temperature, flame-retardant fiber materials, such as glass fiber, ceramic fiber, etc. These materials maintain structural stability in high temperature and even flame environments, effectively insulating heat transfer and thus protecting internal wires, cables or pipes from fire.
The thermal insulation performance of flame retardant sleeves is mainly due to its special material structure and thermal resistance properties. On the one hand, the high porosity and low thermal conductivity of the internal fiber material hinder the heat transfer process and slow down the heat transfer to the interior. On the other hand, the outer layer of flame retardant sleeves is usually coated with a fire-retardant coating or metal layer, which is able to form a protective layer at high temperatures, reflecting heat and further enhancing the thermal insulation.
Flame retardant sleeves have been widely used in many fields due to their excellent thermal insulation performance and fire protection function. In the construction industry, flame-retardant sleeves are used to protect wires, cables, and piping systems from the spread of fire; In the petrochemical industry, it is used for thermal insulation protection of high-temperature pipelines to ensure production safety; In addition, in aerospace, automobile manufacturing and other fields, flame retardant casing also plays an irreplaceable role.
