Roving für Sheet Moulding Compounds (SMC)

Rovings are produced by directly winding a certain number of individual fibers from the bushing without twist whose surface are coated with a silane-based size . They are typically used to produce GRP FRP pipes, pressure vessels, transportation, aviation and space, military and electrical sectors, grating and profiles. And when covereted into woven roving can be used for boats and chemical storage tanks etc. TECHNICAL REQUIREMENTS : PRODUCT CHARACTERISTICES: *R2O content : ≤0.80% * High fiber strength *Coupling agent : Silane * Good integrity and ribboization *Moisture : ≤0.10% * Complete and fast wet-out in resins *Filament diameter : 14µm * Good moisture resistance and low fuzz *Loss on ignition : 1.55%+_0.20% Easychopped
