Polyphenylensulfide

     The fabric is acid resistant, hydrolysis resistant that is why it is used for filtering aggressive gases (gases containing sulfur and acids)

     - the given filtering fabric can have the following chemical treatments:

• treatment reinforcing the cleaning capacity of the material;
• oil and water resistance treatment;
• surface coating of Teflon;
• impregnation of fibers with Teflon and water and oil repellence treatment;
• surface layer (coating) resistant to sparks.
