Manufactured from E-type glass. Offered as a wound which is produced by winding parallel strips of strand. Free from looping. Features low static electrisation compliance and minor fraying. Very good chopping qualities. Designed for processing by means of open mould spraying with the use of polystyrene resins. Very good wet-out qualities and quick release of air bubbles during laminate moulding process.

ZenTron high strength roving is a single-end S-2 Glass roving product that consists of numerous L or T Filament continuous glass strands gathered without mechanical twist into a single bundle and treated with one of two epoxy-compatible size systems.
ZenTron is suitable for a number of composite and non-composite processes and applications, including weaving, filament winding, pultrusion, and texturizing. The 758 size system was developed for composite and reinforcement applications, while the 721B size system was developed for texturizing and thermal applications.
ZenTron products are described with the size chemistry designator as well as the nominal yield in yards per pound.
There are two families of ZenTron products - L Filament and T Filament.

Direct Rovings deliver excellent processing and mechanical properties for the composite part.
The strands offer compatibility with most resin systems including polyester, vinyl ester, epoxy, phenolic, polypropylene and polyamide.
Typical end-use processes for Direct Rovings include:
filament winding to manufacture hollow tubular structures such as pipes, storage tanks, pressure vessels
pultrusion for composite profiles used in consumer goods, sports and leisure, telecommunications and infrastructure parts
knitting and weaving where the semi-finished product (fabric) can be used in a wide range of applications (wind energy, marine, transportation sports and leisure and infrastructure)
Using LFT (Long Fibre Thermoplastic) Direct Roving reinforcement in thermoplastic processes enables moulders to produce structural or semi-structural parts for the automotive industry compounding the fibreglass in-line with injection or compression moulding techniques.
