Polypropylene Felt Filter Cloth | Filter Press Cloths

Non-woven and calendered, polypropylene felt has all the attributes of polypropylene, including lightness, high strength and excellent resistance to most acids and alkalis, with the added benefit of improved cake release due to the calendered surface and greater gasketing or sealing properties due to the increase in the thickness of the cloth. To further improve its sealing qualities, a latex border can be applied to the individual cloths.

HEAT RESISTANCE: 190 ºF
