Filament winding glass roving
The direc roving for producing glass pipe with winding process
Direct roving for filament winding
E glass direct roving (E312) for filament winding (alo called Hoop roving) is coated with silane compatible with unsaturated polyester, vinylester and epoxy resins. It is mainly used to produce FRP pipes, pressure vessels, chemical storage tanks and complicated FRP products etc. It is widely used in oil, gas, chemical industry and mining and so on.
