The protective function of flame-retardant felt

　　As the name "flame-retardant needle-punched nonwoven felt" suggests, it literally means that it can prevent combustible materials from burning. This... Flame-retardant felt Primarily used in public entertainment venues, its main function is fire-retardant treatment. In the event of a fire, flame-retardant needle-punched felt can be used to cover the flames, thereby preventing the fire from spreading.

　　Flame-retardant needle-punched felt has excellent flame-retardant performance and offers a certain degree of protection when used. It also has decorative appeal, as it can be made in a wide variety of colors, making it indistinguishable from ordinary decorative items.

　　Flame-retardant felt for acupuncture applications has a certain amount of flame-retardant material added during production, giving it flame-retardant properties when used. It can also be custom-made into various shapes for enhanced usability.

　　Flame-retardant felt is primarily used in engineering applications during winter and is made by combining two layers of flame-retardant felt with non-woven fabric. In addition to its excellent insulation performance, this material also boasts relatively stable flame-retardant properties. Moreover, thanks to the protective layer of non-woven fabric, this product exhibits strong reusability. Nowadays, during winter construction, it’s common to purchase winter thermal blankets—especially in civil engineering projects. For instance, concrete vibration and frost damage can compromise concrete strength and pose structural safety risks. However, when using this flame-retardant felt blanket, such issues simply don’t arise, as it has a low thermal conductivity and delivers outstanding thermal insulation performance. Its raw material consists of unworn old clothing, making it just as easy to use in winter as wearing a cotton-padded jacket over concrete. This thermal blanket can be employed not only for winter concrete insulation but also for summer concrete curing. It offers excellent sun protection and effectively prevents concrete from cracking. Furthermore, it’s highly durable and cost-effective overall, allowing it to last several years. It can also serve as an insulating felt for cement curing and concrete maintenance.

　　One type is thermal insulation cotton felt, also known as needle-punched flame-retardant felt. It’s primarily used for curing concrete during winter construction and can also be employed to cover building materials that are sensitive to freezing or to protect earthworks in excavation pits. This material consists of two layers of high-insulation black cotton felt, which undergo multiple needle-punching operations during the composite process, giving it excellent reusability and a pleasantly elastic texture. Of course, nowadays most construction projects require insulation materials to be fire-resistant. This flame-retardant felt is inherently flame-retardant throughout its manufacturing process, ensuring highly stable fire performance and allowing for worry-free use.

　　This is engineering insulation. Flame-retardant felt The upgraded product is made by laminating flame-retardant nonwoven fabric onto needle-punched felt. Although its thermal insulation performance hasn't improved significantly, its reusability has greatly enhanced—there’s not much difference in that regard. It also looks more elegant and refined, with a noticeably finer finish. In fact, its price remains relatively high. However, considering its excellent reusability, when you take everything into account, the price of this flame-retardant felt isn’t higher than that of other products on the market—it might even be slightly cheaper.
