FMS compound Needle Punched Felt is a type of filter fabric that is resistant to high temperatures. It is made from a combination of glass fiber with P84, aramid, and PPS fibers. The fabric has a unique three-dimensional structure that allows for low air resistance. The addition of P84, which has a leaf-like fiber, increases the surface area of the filter by 80%, making it easier to collect dust. It also enhances the cohesion of the fibers, allowing it to withstand high wind speeds that are 50% higher than normal. Additionally, the fabric has excellent abrasion resistance. Due to these properties, FMS compound Needle Punched Felt is commonly used in industries such as metallurgy, chemicals, coal-fired boilers, incinerators, and cement plants for dust collection and smoke filtration in high-temperature environments.
