Property Improvement of Recycled Nylon 6 by Thermoplastic Poly(Ether-Ester) Elastomer and Wollastonite

Abstract:

Recycled nylon 6/thermoplastic poly (ether-ester) elastomer (Hytrel) (R-N6/H) composites filled with various contents of wollastonite (WT) (10, 20 and 30 phr) were prepared using the twin-screw extrusion and injection molding process. In this study, the blend and composite materials were characterized in terms of mechanical and morphological properties. The results showed that the impact strength of the R-N6/H blend was improved with the addition of Hytrel, whereas the tensile strength, tensile modulus, flexural strength and flexural modulus of the R-N6/H blend were decreased. Then, the R-N6/H blend was filled with WT to prepare composites. Interestingly, the incorporation of WT in the R-N6/H blend overcame the inferior properties of recycle blend materials by the mechanical properties enhancing. Despite the good mechanical properties of WT composite materials, they were still affected the elastic properties due to the stiffness characteristic of WT.
