The invention relates a plasticized polymeric composition comprising (i) PHB with the proviso that the PHB and its co-polymers of PHB are produced by a bio-polymer extraction process, characterized by the fact that the concentrated cellular material, previously dried or not, is mixed to an adequate solvent, specifically superior alcohol, preferably with a chain with more than 3 carbon atoms, or any other of its acetates, preferably the isoamyl alcohol, amyl acetate, isoamyl acetate or the fusel oil as described by the Brazilian Patent PI 9302312-0 published in 04/30/2002 (ii) a) Fatty alcohols of chain length from 6 to 30 carbon (C6-C30) with the proviso that the fatty alcohols can be saturated or olefinically unsaturated linear or branched and b) glycerol esters of fatty acids with 6 to 24 carbon atoms with the proviso that the fatty acids can be saturated or olefinically unsaturated, linear or branched and optional (iii) additives with the proviso that the additives are composed by thermal stabilization system, constituted by: primary antioxidant as Phenol hindered; secondary antioxidant as organic phosphites; thermal stabilizers as lactone; sorbitol and sodium benzoate as nucleants and starch, wood powder, cane bagasse fibers, rice pod fibers and sisal fibers as fillers. |
