Owens Corning (Toledo, OH, US) launched five new products at the JEC Europe show. These included PulStrand 4100 single-end roving for pultrusion, compatible with polyester, vinyl ester, epoxy and polyure- thane resin systems. Compared to competitive glass fibers, the new roving reportedly offers superior processing qualities, with higher flexural and ultimate shear strength, and enables faster pultrusion line speed, while providing better modulus and durability in pultruded parts.

Another new offering, HydroStrand 258 chopped strands, provides good properties in polyamide resins, particularly in glycol-resistant PA formulations. Up to a 22% increase in impact strength and 13% increase in impact after hydrolysis is reported, in applications such as oil and fluid pump housings and oil pans.

Also on offer for the automotive market was Performax SE4850 roving for polypropylene (PP) direct long fiber thermoplastic (D-LFT) molding, where the glass roving’s good adhesion to PP reportedly improves the resulting composite’s mechanical properties by as much as 80%.

Another product, TeleStrand 2000 UV-series glass roving, brings benefits to customers who produce optical fiber cables, where the impregnated glass fiber acts as a central strength member in the cable assembly. Owens Corning sees significant demand for this product in areas of the world where communication and digital networks are being expanded.
