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.

Why do you choose polyester filter cloth?

Excellent combination properties such as sleekness, high tensile strength, wear resistance and permeability, empower it to be an effective and popular filtration media. Various types of polyester yarns are provided to satisfy particular applications. For example, multifilament filter cloth not only strengthens its tensile strength but also ensures good cake release. Different woven patterns including plain, stain and twill, are designed with special purposes.
