HDPE, NR and thermoplastic tapioca starch (TPS). Several previous studies have reported that blends with starch exhibit a marked decrease in tensile properties because the incorporation of starch interferes in the adhesion between the component phases.Therefore, based on this research work, the mechanical properties were improved by NR vulcanization, which compensated for the deterioration in properties due to TPS loading.

Some commercial thermoplastic starch polymer based products were highlighted in Table 6.1, and some of them can be examined in more detail in this section. Probably one of the first starch based products developed was the National Starch expanded starch foam packaging material ECO-FOAM . ECO-FOAM materials are derived from maize or tapioca starch and include modified starches. This relatively short-term, protected-environment packaging use is ideal for thermoplastic starch polymers. National starch now has additional thermoplastic starch materials, blends and speciality hydrophobic thermoplastic starches for a range of apphcations including injection moulded toys, extruded sheet and blown film apphcations.

It is an aliphatic polyester derived from renewable resources, such as com starch, tapioca roots, chips or starch, or sugarcane. Polylactic acid or polylactide (PLA) can withstand temperatures up to 110 °C [69]. PLA is soluble in chlorinated solvents, hot benzene, tetrahydrofuran, and dioxane [70]. It can be processed like other thermoplastics into fiber (for example, using conventional melt spinning processes) and film. Due to the chiral nature of lactic acid, several distinct forms of polylactide exist ... 

Synthesis PL A is a thermoplastic aliphatic polyester which is formed by condensation polymerization of lactic acid, as mentioned in the preceding. Lactic acid is isolated from tapioca, corn and other plant root starches, sugarcanes, or other resources. Bacterial fermentation is normally used to produce lactic acid... 

Starch. Starch, thermoplastic (qv) (41,42) is a major agricultural commodity and, by far, the most inexpensive commercial biopoljuner it is the only biopolymer that is competitive with polyethylene in price. Annual world production, over 32 million metric tons, is from corn (maize), potatoes, rice, tapioca (cassava), barley, wheat, and other crops. Approximately 16 million metric tons are produced in the United States each year, mainly by extraction from corn but also from potatoes, wheat, and other sources. 

Starch-based polymers can be produced from potato, com, wheat, cassava, or tapioca. In the United States and Europe, com starch is the predominate source for starch-based polymers. Corn starch is mostly used for animal feed. Starch-based polymers can be processed on traditional thermoplastic forming operations of injection molding, extmsion, blow molding, compression molding, rotational molding, etc. Starch can be made from corn or vegetable oils and other renewable sources. The most common plasticizers for starch are water and glycerol. 

This is a thermoplastic starch made from potatoes, wheat, maize or tapioca. The applications are found in food packaging, dog toys and veterinary accessories, and for injection moulding of complex parts.
