Direct Roving for Structural Thermoplastics
Direct roving - also called single-end roving – for structural thermoplastics is used to produce tapes, woven and non-crimp (NCF) fiberglass fabric. During the fiberglass production the direct roving is treated with a special sizing to ensure compatibility with resins such as PP, PA or High-Heat polymers. Tapes are mainly used in winding, tape-laying or cross-ply consolidation processes, while different fabric types are typically used for organosheet production.

"StarRov® is a single-end roving (direct roving) ideal for thermoplastics. It is perfect for fabric processes as it provides a wide and uniform strand width which allows to produce a superior fabric without gaps. StarRov® 490 is the material of choice for PP, StarRov® 895 for PA and StarRov® 853 for High-Heat polymers."
What is a single-end roving (direct roving)?
A direct roving or single-end roving is manufactured by winding fiberglass directly into a clearly defined tex or yield. It is designed to be used mainly as an input for weaving processes, providing easy unwinding due to even tension, low fuzz generation and excellent wettability. It can be utilized in different process technologies, such as pultrusion or filament winding. The end-use composites applications can be found in infrastructure, building, marine, sport & leisure, and water transportation.
