Full definition
Polychloroprene (CR) sheet with one or more plies of woven fabric (nylon PA6/PA66, polyester PET, or aramid) embedded between rubber layers, dramatically increasing tensile strength (2-5x unreinforced), tear resistance, and dimensional stability while reducing elongation. Construction: 1-ply (standard) or 2-ply (heavy-duty) fabric, sandwiched between neoprene rubber covers of specified thickness. Total sheet thickness: 1.5-12 mm. The fabric is treated with RFL (resorcinol-formaldehyde-latex) adhesive system for strong rubber-to-fabric bond (min 3.5 N/mm per ISO 252). Fabric-reinforced neoprene withstands higher pressures and mechanical loads without the distortion and cold flow that unreinforced sheet would exhibit. Applications: pump and valve diaphragms (the primary application — fabric prevents ballooning under pressure), bellows, expansion joints (piping and ducting), reinforced gaskets for higher pressures, rubber-lined equipment, and flex connectors. Material selection: nylon fabric provides flexibility and impact resistance; polyester provides lower elongation and better dimensional stability. Per ASTM D2000 for compound, manufacturer specifications for laminate.
