The modification of properties of thermoplastic starch materials: Combining potato starch with natural rubber and epoxidized natural rubber

摘要: Abstract In this paper, natural rubber (NR) and epoxidized (ENR) are used as potential modifiers of thermoplastic potato starch (TPS). The mechanical thermal properties, water absorption, biodegradability were tested. results show that ENR can be a compatibilizer for NR TPS. As the content (mainly content) increases, tensile strength material decreases elongation at break increases. With increasing content, changes in various properties unexpected. development ternary blend enables modified to have an expected good property. Low blends exhibit high biodegradability. developed processed via compression molding. TPS, unvucanized NR, all-natural green materials, so provides new ideas environmentally friendly materials.
