It is a Fiberglass roving produced by directly winding a certain number of individual fibers form the bushing without twist,it is coated with a silane-based size and is designed for reinforcing unsaturated polyester, epoxy,vinyl ester and phenolic resins. it is specially used to produce GRP pipes, pressure vessels, gratings and profiles and, when converted into woven roving, boats and chemical storage tanks, with filament winding, pultrusion and weaving process
Assembled roving represent an untwisted strand, made up of several evenly strained complex yarns.
Rovings are manufactured according to Technical Specifications 5769-026-00204990-2005.
Assembled roving represent an untwisted strand, made up of several evenly strained complex yarns. Complex yarns for assembled roving are made of basalt crumb.
