The graph above shows the result of tensile load applied longitudinally to three laminate samples made with Polystrand™ continuous glass fiber reinforced polypropylene in 2-, 4- and 6-ply configurations, illustrated below.

Maxxam™ FR Polypropylene Solutions provide cost savings and improve data processing capabilities

Drying non-halogenated materials is suggested. 2 hours @ 100 (38) Moisture Range (%) Not required

One example is such a blend is SEBS with polypropylene (PP).

Our extensive portfolio of specialty colorants helps producers of synthetic fibers and nonwovens achieve brilliant colors and optimal dyeing of polyester, polypropylene and polyamide fibers.

Not all GLS™ TPEs will bond to all types of substrates; for example, a Dynaflex™ TPE that bonds to polypropylene (PP) will not adhere to polycarbonate (PC). Most Dynaflex™, Versaflex™, Versalloy™ and OnFlex™ materials are suitable for two-shot or insert molding with a polypropylene (PP) as the insert or substrate. Not all GLS TPEs will bond to all types of substrates; for example, a Dynaflex™ TPE that bonds to polypropylene (PP) will not adhere to polycarbonate (PC).
