Direct Rovings consist of continuous filaments bonded into a single strand and wound onto a bobbin shape. 3B Direct Rovings are made out of Advantex® E-CR glass or HiPer-tex™ glass both recognized as benchmarks in the fibreglass industry for their environmental green manufacturing footprints.
Advantex® glass is a boron-free E-CR glass that shows significantly improved corrosion resistance properties over standard E-glass. Advantex® E-CR glass complies with ASTM D578 and ISO 2078 standards.
HiPer-tex™ glass is a high performance R-glass. Designed for high load bearings it also offers an improved thermal resistance over Advantex® glass. HiPer-tex™ glass is also a boron-free glass that presents improved corrosion resistance. Our products show excellent processability in your composites processes whatever they are:
- filament winding (manufacturing of hollow tubular or cylindrical structures): pipes, storage tanks, pressure vessels
- pultrusion (production of profiles): tools, industrial profiles, telecommunications cables, infrastructure parts
- knitting & weaving (manufacturing of woven rovings and multi-axial fabrics): semi-finished products used in various applications such as windmill blades, marine, transportation, etc.
- Texturisation: acoustics components
- In-line compounding injection or compression moulding: long fibreglass reinforced thermoplastic (LFTP) for semi-structural & structural parts.
Chopped strand products are Advantex® glass fibre bundles of consistent shape and size. They are made by chopping, into a specified length, continuous glass filaments coated with a chemical sizing, which ensures the compatibility with the resin to reinforce.
They are densified using a unique manufacturing technology. The direct result is a high bulk density enabling these engineered products to offer excellent feeding properties and very low level of fine fibres. Benefits for customers are lower operating costs and better manufacturing efficiency via reduced cleaning downtime and maintenance. That is also how 3B contributes to a more sustainable future. Chopped strands are used to reinforce thermoplastic and thermoset resins in various processes, such as compounding, injection-moulding, compression moulding, etc.
