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 polyurethane resin systems. The new roving reportedly offers superior processing qualities with a higher flexural and ultimate shear strength than competitive glass, which allows 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% percent 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 direct long fiber thermoplastic (DFLT) molding, where the glass roving allowed good adhesion to PP can improve composite mechanical properties by up to 80 percent. Another product, TeleStrand 2000 UV series glass roving brings benefits to customers producing optical fiber cables, where the impregnated glass fiber acts as a central strength member in the cable assembly. Owens Corning see significant demand for this product in areas of the world where communication and digital networks are being expanded.

The project intends to improve pultrusion technology so that it can manufacture in a continuous way and out of autoclave.
