E-Glass DIRECT ROVING

E-glass direct rovings is made directly from a 2000 tips or a 4000 tips bushing which are produced by winding a certain number of individual fibers directly from the bushing without twist into rovings. The surface of strands is coated with a sialne-based size which impacts a specific application property to the product. Direct Rovings can be compatible with polyester, vinyl ester and expox resins and are specially designed as reinforcement for FRP pipes, pressure vessels, gratings and profiles and, when converted into woven rovings, for boats and chemical tanks storage tanks.
