One challenge faced by the plastics industry is that crude oil will become scarcer and more expensive in the future. Furthermore, an increase in plastic waste is leading to a strongly growing demand for sustainable alternatives to traditional, crude oil-based polymers in the packaging sector. The aim of this study was to investigate the influence of the incorporation of whey protein isolates (WPIs) on the technofunctional properties of ethylene vinyl acetate (EVA) films. The compounding EVA with WPI was conducted in a co-rotating twin-screw extruder at varying processing temperatures. WPI and hydrolysed WPI with a degree of hydrolysis of 10% were used up to 35% (w/w) as filler. The tensile strength and elongation at break of the resulting EVA-based films decreased significantly with increasing filler content. Because of the hydrophilicity of WPI, the water vapour permeability of the films increased. Advantageously, the oxygen barrier was enhanced by 50-80% compared with that of pure EVA films, which offered the potential of using whey proteins as a filler in compounds for packaging materials for their oxygen barrier properties. In addition, this study provides a promising perspective on the thermoplastic processing of whey protein formulations in the future.

“…Melting peak displacement is an indication of molecular interaction of the components [42] and is already known from other binder systems. [43] It is described in the literature [44] that binary systems of polymers are normally mixtures that split into two metastable phases, in which both component materials are present. Displaced melting temperatures suggest that there is distinct solubility of both binder components in each other, therefore shifting their characteristic melting temperatures.…”

Realization of a Titanium Spinal Implant with a Gradient in Porosity by 2‐Component‐Metal Injection Moulding

et al. 2013

2‐Component‐Metal Injection Moulding (2‐C‐MIM) is a technique derived from plastics industry which has been adapted to metal powders. In the present work, the production of titanium implants with a gradient in porosity was demonstrated by using this technology, starting from titanium feedstocks with and without space holder particles (NaCl, 350–500 µm). Binder systems specially tailored for the application were developed. Compared to established production routes, the net‐shape fabrication of titanium implants by 2‐C‐MIM promises a significant reduction of cost if aiming at large scale production. The feasibility study was accompanied by a detailed characterisation of each production step of 2‐C‐MIM process including influence of MIM processing on mechanical properties.
