Glass Fibre Needle Punched Felt is a high performance high temperature filter media designed for dust collection filter bags in harsh industrial environments. It is made of premium glass fibres processed by needle punching technology and reinforced with a woven glass fibre scrim backing, giving the fabric high tensile strength, dimensional stability and excellent filtration efficiency. The material withstands a continuous operating temperature of 260°C and instantaneous temperatures up to 280°C, making it one of the most cost-effective solutions for high temperature dust filtration.
Compared with ordinary woven glass fibre filter cloth, the needle punched felt structure forms a deep-loading porous filter layer, which provides higher dust collection efficiency and lower pressure drop. Various surface treatments such as calendering, PTFE coating, PTFE membrane lamination and acid washing are available to improve dust cake release, chemical resistance and service life.
