E-glass Direct Roving for Filament Winding
E glass Direct Roving for Filament Winding (also called Hoop Roving) is coated with silane sizing which compatible with unsaturated polyester, vinylester and epoxy resins. It is mainly used for producing FRP (Fiberglass Reinforced Plastics) pipes, pressure vessels, chemical storage tanks and complicated FRP (Fiberglass Reinforced Polymer) products etc. It is widely used in oil, gas, chemical industry, mining and so on.
