Polypropylene-based composites are prepared using hydrolyzed collagen (HC) from wastes of the leather industry. Blends of polypropylene and HC were studied as a function of the blend composition ratio with the aim of developing a formulation with optimal physical-chemical and mechanical properties. The prepared mixtures were characterized by thermal analyses and mechanical test. Blends with content up to of 20-30% of collagen hydrolizate are susceptible to be melt processed to provide transparent, cohesive and flexible films. In front of positive results the reutilization of collagen hydrolizate derived from the tannery industry appears feasible for production of thermoplastic items for applications in packaging and agricultural segments.

Abstract

Polypropylene-based composites are prepared using hydrolyzed collagen (HC) from wastes of the leather industry. Blends of polypropylene and HC were studied as a function of the blend composition ratio with the aim of developing a formulation with optimal physical-chemical and mechanical properties. The prepared mixtures were characterized by thermal analyses and mechanical test. Blends with content up to of 20-30% of collagen hydrolizate are susceptible to be melt processed to provide transparent, cohesive and flexible films. In front of positive results the reutilization of collagen hydrolizate derived from the tannery industry appears feasible for production of thermoplastic items for applications in packaging and agricultural segments.
