EFFECT OF AGAR AND KAPPA-CARRAGEENAN ON THERMAL AND MECHANICAL PROPERTIES OF THERMO PLASTIC STARCH (TPS)

Effect of Agar and kappa-Carrageenan on Thermal Mechanical Properties Thermo Plastic Starch (TPS) Thermoplastic starch needs to be blend with other materials because its limited properties. In order gain the desired properties, interaction between added component (filler, plasticizer, second polymer, etc) must concerned as it can affect performances final product. has been successfully made mixing compression molding addition agar kappa-carrageenan. The effect material studied FTIR, Tensile, DSC, TGA investigate their mechanical thermal FTIR spectrum shown shifting around methyl group (C-H), a carboxyl (C-O), hydroxyl (O-H). analysis results presented different patterns in melting degradation behavior. tensile strength value did not show significant improvement presence It is that kappa-carrageenan affects behavior but does significantly impact
