“…This is consistent with earlier work, which suggested that better consolidation would result in somewhat lower moduli. 1 The injection rate had no clear effect on secant modulus and was opposite to the effect on elongation at break. If the material were more ductile, the elongation at break would have increased while the secant modulus decreased.…”

“…Alternatives have been developed that are sustainable and biodegradable and are often based on vegetable or animal proteins. 1 Some of these compete against food production, which has led to second-generation biopolymers, which are produced from byproducts. Blood meal is available in large volumes and does not compete against food production.…”

“…It has a high protein content (85 wt%), which makes it a good starting material to produce thermoplastics that may also be compostable. 2 Blood meal-based thermoplastics have been developed previously, 1 but to widen the range of industrial applications, production must be cheap and possible in large quantities. Injection molding is well suited for high volume production; the process is cyclical and has three distinct stages: plasticization, mold filling, and cooling.…”

Protein-based thermoplastics offer an attractive alternative to petroleum-based plastics if their properties allow for large volume production using processes such as injection molding. A fractional factorial design was used to analyze the influence of injection-molding parameters (melt temperature, tool temperature, injection rate, holding pressure, and cooling time) on the injection-molding process (maximum injection pressure, injection pressure curve) and mechanical properties (tensile strength, elongation at break, secant modulus) of blood meal-based thermoplastics. Optimal mechanical properties were obtained at higher tool and melt temperatures while the injection rate was unimportant. The most important injection parameter was the holding pressure, which has to be lowered when using a higher melt temperature, which was preferred for better elongation at break. A lower holding pressure also produced moldings with a higher modulus, which could be good for demolding. Blood meal-based thermoplastics behaved mostly like standard thermoplastics, without any significant deviations. Within a workable processing window, its mechanical properties were largely unaffected by processing conditions, but as with any thermoplastic, care must be taken to select the best injection-molding parameter settings to achieve optimal part quality and high processability.

“…Novatein Thermoplastic Protein (NTP) is a new developed material from bloodmeal by Novatein Bioplastic Technologies in Hamilton, New Zealand [1], [2]. Previous research by Verbeek and van den Berg [3]- [5] showed that dry processing techniques, such as extrusion and injection moulding were successfully used to produce NTP with good mechanical properties.…”

Abstract-The use of dual compatibilizers, poly (2-ethyl-2-oxazoline) (PEOX) and polymeric methylene diphenyl diisocyanate (pMDI) in Novatein thermoplastic protein from bloodmeal (NTP) and PBS blends were investigated. A composition of 50% of NTP was used for all formulations with different percentage compatibilizer. Mechanical, morphology, thermal and water absorption were used as analysis methods to study blend properties. To improve compatibility, two different approaches to blending the compatibilizers were used. Firstly, PEOX was added before extrusion this has improved the blend's tensile strength. Secondly, addition of PEOX during NTP production followed by pMDI added before injection molding, showed a futher improvement in tensile strength. SEM revealed that PEOX has improved the dispersion of NTP and pMDI has strengthened the adhesion between phases consistent with mechanical property results. A broad tan δ peak in DMA analysis was obtained indicated improved compatibility in blends using two compatibilizers. In spite of that, the addition of dual compatibilizer has reduced the water resistance of PBS.

Short‐Term Viscoelastic Properties of Bloodmeal‐Based Thermoplastics

ABSTRACT:The effects of sodium sulfite (SS) content and injection molding temperature on the viscoelasticity of bloodmeal-based thermoplastics were assessed using creep, recovery, and stress relaxation. Both SS and processing temperature affected standard mechanical properties and time-dependent behavior. Increased SS content led to greater creep, greater strain at break, and reduced modulus and mechanical strength of the material. Furthermore, the use of a higher injection molding temperature also reduced modulus and strength. Higher molding temperature also caused an increase in the fraction of creep recovered in 20 min. These results confirmed that increased SS increased chain mobility and that injection molding at 140• C instead of 120• C did not cause excessive thermal cross-linking. C
