Polyester filter and dust collection fabrics have very good resistance to chemicals, abrasion and dry heat degradation, plus excellent dimensional stability. Typical applications include dust collection, particularly in the cement industry; acid refining of ore; anode bags for electroplating; tubular battery separation fabrics.HEAT RESISTANCE: 275 – 300 ºF As an important factor of filter press, polyester filter cloth has been widely accepted by an increasing number of manufacturers and users of filter press for its strongest acid-resistance and excellent resistance against elevated temperature up to 302 °F. Surface finishes can be singed, calendered and heat set, each of which has its special property and purpose.
