The objective of this project is to develop and validate formulations with characteristics and proprieties for using it in rotomoulding process. Its wish to propose to the industry an appropriate materials row for the plastic pieces conception and fabrication, innovative and differentiated, with new characteristics which are not present on the market. For this, we envisage to implement the following types of formulations: a) more environmentally friendly: based on recycled materials, biobased and integrating natural residues. b) Formulations with hydrophobicity or superhydrophobicity properties. c) Formulations more slight with better thermic, dimensional stability and isolation properties.
