3B Fibreglass R25H

3B Fiberglass R25H consist of continuous glass filaments bonded into a single strand and wound onto a bobbin shape. A proprietary sizing applied on the fibers assures excellent resin-to-glass bonding.Corrosion resistant R25H Direct Rovings made of Advantex® glass are specifically designed for filament winding processes (continuous or discontinuous) for the manufacturing of composite pipes. The silane sizing of R25H is designed for excellent adhesion to thermoset resins and is also drinking water contact approved. Also, combination of high temperature resistance of E-CR Advantex® glass and easy texturisation of R25H Direct Rovings make them ideal for muffler filling.R25H Direct Rovings made of Advantex® glass are also used in pultrusion or weaving-knitting processes under specific conditions; contact us for further assistance.

Packaging & Availability

Packaging

Bobbins are individually wrapped with a stretched plastic film for protection, improved handling and to allow optimum transfer from bobbin to bobbin. Nominal weights of C and V bobbins are respectively 25 kg and 34 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 bobbins handling for operators.

Storage & Handling

Storage: Storage in a cool and dry warehouse into the original packaging is formally recommended. If this condition is maintained, the glass fiber 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%.
