25mm Ceramic Fiber Blanket
Product Introduction
25mm ceramic fiber blanket is processed by continuous process, and the fibers are evenly interwoven after needle punching, which has excellent tensile strength. This product does not contain any adhesive.
25mm ceramic fiber needle punched blanket provides a variety of densities and thicknesses, providing customers with diverse choices to create a perfect insulation system and create lucrative profits.
25mm ceramic fiber blanket has excellent resistance to most chemicals, except hydrofluoric acid, phosphoric acid and strong alkali. 25mm ceramic fiber blanket has excellent oil resistance, and its insulation and physical properties can be fully restored after drying, ensuring long-term durability and reliability in harsh environments.

What is the difference between ceramic fiber blanket and aluminum silicate needle-punched blanket?
Ceramic fiber blanket and aluminum silicate needle-punched blanket are the same product, just two different names, the main components are aluminum oxide and silicon dioxide.
Ceramic fiber blanket (aluminum silicate needle-punched blanket) melts high-purity ceramic fiber cotton in a resistance furnace, adopts the production process of blowing or spinning into fiber, and is made through needle-punching, heat setting, horizontal and vertical cutting, rolling and other processes. It does not contain any binder to ensure that the product is stable in various environments.
Ceramic fiber blanket (aluminum silicate needle-punched blanket) has uniform fiber length and diameter, low slag ball content, and the double-sided needle-punched production process has comprehensively improved its thickness uniformity, anti-delamination, anti-wind erosion, flexibility and tensile strength. It can be widely used in the fields of refractory, heat insulation and thermal insulation in various industries.
