Tri-component Recycled PVC/PE-HD Material Composite with Keratin Fibres

Presented in the article are some mechanical and processing properties of composites prepared from two recycled immiscible polymers: poly(vinyl chloride) (PVC) and high density polyethylene (PE-HD), and keratin fibres used as a filler. The simplex-centroid design technique was adopted to fix the make-up of the composites. Results of the investigations are presented in the form of triangular graphs which illustrate the content percentage of singular components in the composite. It was found that the blend of PVC and PE-HD is suitable as a matrix in polymeric composites to hold keratin fibres as the filler. On the grounds of results obtained, the opportunity is presented to adopt a composition of the composite that responds to a complex of desired properties (within assumed limits of the singular components).
