A thermoplastic starch (TPS) material is developed, based on corn starch plasticized with glycerol and citric acid in a 9:3:1 ratio and further bonded with isinglass and mono- and diglycerides of fatty acids (E471). In TPS, leather fragments, in the amount of 7.5 15 or 22.5 g/100 g of dry matter, were also introduced.

Maleated polypropylene (MAPP) was supplied by ExxonMobil (USA) (ρ = 0.9 g/cm 3 and MFI of 125 g/10 min (1.2 kg, 190 °C)) and had a maleic …
The samples were subsequently mixed using a two-roll mill (PI-140, Pirom-Olarn Co. Ltd., Bangkok, Thailand) to apply shear and induce reaction at 130 °C for 10 min. Table 1 lists the composition and code names of the TPS blends with CHG. The samples were compressed into sheets for evaluating their properties using a hot compress at 130 °C for ...
The coagula was thoroughly washed with water and dried at 80[degrees]C until the moisture content was less than 2%. The dried compound was mixed with stearic acid, which acts as a softener, and curing agent, and sulfur, by using two-roll mill, followed by vulcanization process at 70[degrees]C 17].
The development of bio-based materials has been a consequence of the environmental awareness generated over time. The versatility of native starch is a promising starting point for manufacturing environmentally friendly materials. This work aims to compile information on the advancements in research on thermoplastic starch (TPS) nanocomposites after the addition …
The values were in the range from 0.87 × 10 −3 m/s to 4.30 × 10 −3 m/s and 6.5 × 10 −11 m 2 /s to 3.3 × 10 −10 m 2 /s, for nisin apparent desorption and diffusion coefficients, respectively.
The diameter of bamboo fiber bundles was about 200 μm, while that of MFC was just a few microns, which was much smaller. Using gap settings in decreasing order of 70, 50, 35, 25, 15, 10, and 5 μm, they processed the mixture of the MFC and PLA in the three-roll mill.

The samples (GMs) were compounded by using two roll mill …
Starch is commonly pretreated with a plasticizer to make it thermoplastic thus enabling melt-processing. However, thermoplastic starch (TPS) alone often cannot meet all the requirements of a packaging material and an environmentally acceptable filler is called for to improve the properties of TPS in such applications.
