Supercritical CO2

Use of supercritical CO2 as an alternative to organic solvents :

• non toxic, non flammable, can be recycled
• adjustable solvent capacity, function of T° and P
• excellent diffusivity
• excellent transport properties
• weak critical parameters (Tc = 31°C, Pc = 74 bar)

Three processes are under development :

• The synthesis of organomodified nanocharges base on clay for the improvement of mechanical thermal and barriers properties of polymers
• The synthesis of mixtures polyester/clay for the synthesis of nanocomposites
• A continuous foaming process of nanocomposites by CO2 expansion.
