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. It is widely used in apparatus, radio, building slot, yacht making, car frame and hand-lay-up GRP products.
