| 20090018235 | ENVIRONMENTALLY DEGRADABLE POLYMERIC COMPOSITION AND PROCESS FOR OBTAINING AN ENVIRONMENTALLY DEGRADABLE POLYMERIC COMPOSITION - The present invention refers to a polymeric composition prepared from a biodegradable polymer defined by poly-hydroxybutyrate (PHB) or copolymers thereof, and at least one other biodegradable polymer, such as polycaprolactone (PCL) and poly (lactic acid) (PLA), so as to alter its structure, and further at least one additive of the type of natural filler and natural fibers, and, optionally, nucleant, thermal stabilizer, processing aid, with the object of preparing an environmentally degradable material. According to the production process described herein, the composition resulting from the mixture of the modified biodegradable polymer and additives can be utilized in the manufacture of injected packages for food products, injected packages for cosmetics, tubes, technical pieces and several injected products. | 01-15-2009 |
| 20090023836 | ENVIRONMENTALLY DEGRADABLE POLYMERIC COMPOSITION AND METHOD FOR OBTAINING AN ENVIRONMENTALLY DEGRADABLE POLYMERIC COMPOSITION - The environmentally degradable polymeric composition is obtained from the biodegradable polymers poly (hydroxybutyrate)-PHB and copolymers thereof and poly (lactic acid)-PLA and, optionally, at least one of the additives defined by: plasticizer of natural origin, such as natural fibers; natural fillers; thermal stabilizer; nucleant; compatibilizer; surface treatment agent; and processing aid. | 01-22-2009 |
| 20090082491 | ENVIRONMENTALLY DEGRADABLE POLYMERIC BLEND AND PROCESS FOR OBTAINING AN ENVIRONMENTALLY DEGRADABLE POLYMERIC BLEND - The present invention refers to an environmentally degradable polymeric blend, comprising biodegradable polymers defined by polyhydroxybutyrate (PHB) or copolymers thereof and Polycaprolactone (PCL) and, optionally, at least one additive defined by a filler, nucleant, thermal stabilizer, processing aid, with the purpose of preparing an environmentally degradable polymeric blend. According to the production process described herein, the blend resulting from the mixture of the biodegradable polymers, PHB and PCL, and at least one additive, can be utilized in the manufacture of injected food packages, injected packages for cosmetics, tubes, technical pieces and several injected products. | 03-26-2009 |
| 20090118398 | Material to be injection molded, process thereof, and use therefore - The present invention refers to an adequate composite material to be prepared by an injection process and to an injection process of a composite material. In accordance with the process of the present invention, the composite material is prepared by carrying out the steps of (i) making the length of the natural fibers uniform; (ii) treating the surface of the natural fibers and of the lignocellulosic residues, if present; (iii) premixing the components of the composite; (iv) extruding and granulating the composite material; and (v) injection molding the material of the composite for the conformation of the parts. | 05-07-2009 |
