Abstract
NAVIA P., DIANA PAOLA; VILLADA C., HÉCTOR SAMUEL and AYALA A., ALFREDO ADOLFO. MECHANICAL EVALUATION OF SEMIRRIGID BIOPLASTICS MADE WITH CASSAVA FLOUR. Rev.Bio.Agro [online]. 2013, vol.11, n.spe, pp.77-84. ISSN 1692-3561.
Abioplasticsemirrigid material was developed from native flour of fourcassava varieties(MBRA 383, MPER 183, CM 4574-7 and CM 7951-5), incorporating fique dust, by thermo-compression technique. The material was obtained by subjecting the raw material mixturein a moldand subsequently it was compressed at 200ºC. The cassava variety suitable for use in thematerial development was MPER 183, with results of lasttensile and flexural resistance of 1,8 MPa ± 0,2 and 3,5 ± 0,2 MPa, respectively, and resistance to impact of 21,2 ± 0,1 J/m. Compression molded samples, obtained in this work are technologically feasible and favorable performance characteristics presented as an alternative to the use of polystyrene foam food packaging applied.
