Fibreglass weaving
Product: E -glass Woven Roving
 1.COMPOSITION AND PRESENTATION
E-glass Woven Rovings are bidirectional fabric made by interweaving direct rovings. Woven Rovings are compatible with many resin systems such as polyester, vinyl ester, epoxy and phenolic resins. Compared with C-glass Woven Roving, it is high in price, and applicable in production of electrical-resistant FRP products and Engineering plastics products while C-glass Woven Rovings are used in general FRP products and Engineering plastics products.
2.PROPERTIES & APPLICATIONS.
Properties:
Free of fuzz,dirt,impurity and other stains, Good covering and degassing properties, High wet strength retention, High mechanical strength Even thickness, Fast wet-out.
Application:
E-Glass Woven Roving is the elementary material of GRP with reinforcement, corrosion-resistance and insulation. Widely used in apparatus,radio, building slot, yacht making, car frame and hand-lay-up GRP products.
