Alkali-free glass fiber direct untwisted roving (hereinafter referred to as direct roving) is drawn directly from the funnel plate. Depending on the resin used, it is categorized into thermosetting direct yarn and thermoplastic direct yarn. Thermosetting direct yarns are suitable for resins like unsaturated polyester, vinyl, epoxy, and polyurethane. They are used in processes such as fiber winding, pultrusion, hand lay-up, and compression molding. End products include pipes, pressure vessels, profiles, and chemical storage tanks. Thermoplastic direct yarns are designed for resins like PP, PA, and others, and are used in processes like LFT, sheet molding, twin-screw extrusion, and GMT.
Thermoplastic Direct Roving
Alkali-free glass fiber direct untwisted roving (hereinafter referred to as direct roving) is drawn directly from the funnel plate. Depending on the resin matched with the infiltrant, it is classified into thermosetting direct yarn and thermoplastic direct yarn.

Thermosetting Direct Roving
CPIC manufactures direct, untwisted rovings, which are continuous single-strand untwisted rovings used in pultrusion molding, fabrics, and checkered fabrics. They are compatible with unsaturated polyester resins (UP), vinyl ester resins (VE), phenolic resins (Phenolic), and epoxy resins (EP). The products can be made with E-glass, ECT-glass, ECR-glass (excellent chemical resistance), and TM-glass (a clear advantage for large-scale FRP products requiring high modulus).
