Industrial felt is made of wool with the characteristics of shrinking and being processed and bonded by machine (not interwoven with warp and weft). Industrial felt is mainly used in industrial construction, which can be used for shockproof, polishing, insulation, sealing, and other functions. Industrial felt has the characteristics of good adhesion and not easy to loosen. Industrial wool felt has good insulation performance and can be used as a thermal insulation material. Industrial felt is elastic and can also be used as a sealing application. Industrial felt can also be processed into parts that can be punched and cut into various shapes, which can be used in different industries and requirements. Industrial felt features: tight organization, small pores, and in manufacturing, it is not limited in thickness like interwoven fabrics, and can be used as a good filtering material. It has good wear resistance and can be used as a material for polishing. 1.
