Owens Corning has developed a glass-fiber roving aimed at electrical applications for glass-fiber-reinforced plastics.
The Toledo, Ohio, firm said its SE 8400 LS is suited to pultruded FRP long-rod insulators for medium- and high-voltage electrical transmission. Compared with previous boron-free glass fibers, the new product has low levels of microscopic bubble voids, which interfere with insulation.
Owens Corning said the fibers have high corrosion and temperature resistance, quick wet-out for polyester, vinyl ester and epoxy resins, and improved glass-to-resin bonding.
