A CGR filter press fabric is specifically designed for CGR plates—which stands for Caulked, Gasketed, Recessed chamber. These plates are engineered for leak-free operations by embedding an O‑ring around the recessed groove, into which the octagonal-shaped cloth is tightly caulked The cloth typically includes a sewn cord or gasket around its edge to ensure a secure fit that prevents wicking or dripping, resulting in drier filter cakes

​

These fabrics are usually made from polypropylene or polyester, available in various weave styles like satin or twill. Polypropylene is a common choice, offering excellent chemical resistance, temperature tolerance, and durability under high pressure and  Cloth sizes range from 400 mm up to 2000 mm and are often factory-cut and edge-sealed with latex or EPDM rubber barrelnecks to minimize leak potential 

🔧 Benefits of CGR Fabric

• Near-zero leakage due to gasket integration in cloth and sealing at plate interfaces 

• Enhanced cloth protection: the recessed design supports the fabric surface for consistent filtration 

• Durability and long service life, even in harsh conditions
