About this product

Direct Roving

3B Direct Rovings consist of continuous filaments bonded into a single strand and wound onto a bobbin shape. A proprietary sizing applied on the fibres assures an excellent resin-to-glass bonding. Corrosion resistant 111A Direct Rovings made of Advantex® glass are specifically designed for weaving processes. The silane sizing of 111A Direct Rovings offers excellent adhesion with thermoset resins and is also drinking water contact approved. 111A Direct Rovings are also used in filament winding processes, and in production of uni-directional fabrics under specific conditions.

FEATURES - Boron-free E-CR glass - Polyester, Vinylester, Epoxy compatible - High strand integrity - Potable water approved - Globally available

BENEFITS - High corrosion resistance - Maximum flexibility on workshops - High efficiency in weaving operations - Suitable for manufacturing of composite drinking water parts - Get flexibility in manufacturing the highest quality wherever you are

PACKAGING Bobbins are individually wrapped with stretched plastic film for protection, improved handling and allowing optimum transfer from bobbin to bobbin. Nominal weights for R and C bobbins are respectively 21 and 25 kg. Two pallet configurations are available: - Bulk Pack: standard packaging, consists of individual bobbins. - Creel Pack: bobbins are connected together for continuous unwinding and no bobbin handling for operators. For detailed information about bobbins, pallet weight, dimensions and layout, please contact us.

STORAGE Storage in a cool and dry warehouse into the original packaging is formally recommended. More precisely ideal storage conditions are a temperature between 15°C and 35°C and a relative humidity comprised between 35% and 75%. If these conditions are maintained, the glass fibre product should not undergo significant changes when stored for extended periods of time. It is also strongly recommended to condition it in the workshop for at least 24 hours before use to prevent condensation. For an optimal processing it is recommended to use the product in ambient conditions (20°C-23°C and a relative humidity of 60%-65%).

Direct Roving Direct Rovings consist of continuous filaments bonded into a single strand and wound onto a bobbin shape. 3B’s Direct Rovings are available in both corrosion resistant E-glass and R-glass formulations. 3B’s Direct Rovings are designed for excellent processability in composites technologies like: filament winding pultrusion knitting & weaving texturisation Long Fibre Technologies (LFT) Our high performance R-glass, HiPer-tex®, is designed for high load bearings thanks to its high stiffness and strength. HiPer-tex® also displays an improved thermal resistance over standard E type glass, and is corrosion as well as acid resistant. Depending on the technology they are designed for, 3B’s Direct Rovings are compatible with Thermoplastic or Thermoset resins as presented in our product portfolio below.
