In industrial filtration applications where high humidity and elevated temperatures are present, the choice of filter media can significantly impact performance and service life. Acrylic Needle Punched Felt is engineered to meet these exacting demands — offering superior moisture resistance and stable performance in temperatures up to 130°C (266°F).
Acrylic needle felt is manufactured from acrylic staple fibers using a needle-punching process, forming a dense and mechanically robust nonwoven fabric. It is commonly used in dust collection systems, especially where high moisture levels or mild chemical exposure would degrade conventional polyester filters.
This material is often finished with surface treatments like singeing, calendering, or PTFE membrane laminating to enhance its anti-stick properties and filtration efficiency.
