FIBERS PROCESSES PRODUCTS MOVING HIGH PERFORMANCE FIBERS FORWARDKEVLAR para -ARAMIDWHY kevlar PARA-ARAMID ?Molecular StructureChemical NamePoly- para -phenylene .HistoryKevlar was first developed by chemist Stephanie Kwolek at DuPont in the 1930 s. It was first commercially used in the 1970 s as a replacement for steel in racing tires. CompositionKevlar is an aromatic polyamide that is characterized by long rigid crystalline polymer chains. para refers to the specific linkage position of the aromatic rings. Longitudinal alignment of the hydrogen bonds enables high tensile strength and Deniers200, 380, 400, 750, 800, 1000, 1420, 2160, 2250, 2840, 3000, : Standard : High : 15% higher tenacity than : Optimized ballistic resistance for armor applications. Key Features High strength to weight ratio Low elongation to break Good heat & flame resistance Good chemical resistance High cut resistance Excellent ballistic propertiesDisadvantages kevlar suffers from UV degradation, which causes strength loss and discoloration Propensity to absorb moisture, up to 5% moisture regain Poor compressive force propertiesFIBER-LINE PROCESS FOR kevlar Coating Twisting Extrusion Pultrusion Precision WindingFIBER-LINE kevlar PRODUCTS Ripcords Strength Members Industrial Fabric Yarn Swellcoat Binder Yarn in between strength members and industrial fabric yarn Belt & Hose Reinforcement Yarn Packing Yarn Wire Harness Y
