3.0mm Double Sided FKM Coated Fiberglass Fabric
1. Product Overview
3.0mm double-sided FKM coated fiberglass fabric is an engineered high-performance composite constructed from a 2-ply high-density woven E-glass substrate encapsulated symmetrically on both sides with vulcanized fluoroelastomer (FKM) rubber. The 2-ply reinforced internal structure provides exceptional tensile strength, multi-axial tear resistance, and blowout prevention under high dynamic mechanical loads and positive/negative duct pressures. The vulcanized FKM coating delivers outstanding resistance to harsh acidic condensates (including sulfuric, hydrochloric, and nitric acids), hydrocarbons, aromatic solvents, oils, and chemical fumes, providing reliable environmental isolation where standard silicone or elastomer coatings degrade.
