HYDAC clamps are available in a wide range of sizes and materials. Polypropylene (pp) is used for standard clamps and Polyamide (PA) or Aluminum (al) for special applications.

Asymmetric reverse osmosis (ro) polyamide (pa) composite membrane may be modified by means of solvent processing technique into pervaporation (PV) membrane for separating organic aqueous solution.

In recent year, PA polyamide, white cardboard, electronic mesh screen and other projects of relatively high technical levels have been launched into production one after another.
