Creates new PolyOne Advanced Composites platform within Specialty Engineered Materials New continuous reinforced thermoplastic composite capability establishes PolyOne at the forefront of "next generation" composite solutions as a leading innovator and producer of continuous reinforced thermoplastic composite technology. 

Fiber-reinforced composites add impact resistance and remove weight Corrosion-resistant thermoset and thermoplastic composites stand up to the harshest environments without the need for paint or rustproofing Filled and reinforced composite materials offer lighter weight, equal strength options versus metal

In addition, various rigid thermoplastics can have reinforcements and/or additives, such as fillers and fibers or color masterbatches, which not only can alter the resultant properties of the substrate, but also the surface chemistry. Furthermore, the material has outstanding adhesion to Ultramid B3G6 (glass reinforced polyamide 6) as demonstrated in Figure 10 and 11.
