Product Information Spun Roving for Pultrusion and Weaving Product Description Spun roving is made by assembling E-glass basic strands. Several basic strands are structured into loops which form the roving. In order to strengthen the construction of this roving, it is braided by another basic strand. Spun roving has a sizing system with a silane coupling agent. Spun roving is compatible with epoxy, unsaturated polyester and vinylester resins. Product applications Spun roving is especially designed for applications requiring additional reinforcement in the transversal direction: pultrusion of profiles, weaving for shipbuilding, etc. Product Reference Example E C 2800 K247 : EC 4000 K247 : glass type : type of process (continuous) : nominal linear weight of roving (tex) : OCVTM Reinforcements code for sizing system Features and PRODUCT Benefits • Good ability to take up complex shapes of profiles by • Good surface aspect on composites • Homogeneous structure; should allow a normal unwinding of the rovings • Even glass / resin distribution Visual characteristics or possible defects • • • • • The rovings have the form of cylindrical cheeses with straight sides and plain faces The color of the rovings should be regular and white Breaks in the basic strands are not glued, but are joined by intermingling the fibers with each other When the rovings are chopped, they should open up into the basic strands in order to obtain a good dispersion of the filaments Rovings should not contain significant defects (spots, damages, deformations, accumulations of strands) which would affect their use, or which would reduce the value of the final product TECHNICAL CHARACTERISTICS (nominal values) Linear weight (TEX)
