Project ID: G4RD-CT-2001-00495
Funded under: FP5-GROWTH
Country: France


A new polymeric material based on n butyl polyacrylates and a Latex Interpenetrated Polymer Networks (LIPN) have been designed, synthesised and characterised. The glass transition of the n butyl acrylate is 100°C. Between 80°C and 170°C, the tan d is 0.7 and shows a plateau like behaviour. The LIPN displays a mean tan d of 0.65 between -11°C and +122°C.With such properties, the n butyl polyacrylates material can be used as high temperature vibrations damping materials. Whereas the LIPN can be used in a more widen range of temperature.

Both materials will be especially suitable for applications requiring temperature independent performances, for instance in aeronautic, civil engineering and automobile industries. Next steps in the R&D program include processing of laboratory samples, pilot unit set up and industrialisation with SPADD device as target application.

Depending on the market spreading of SPADD system from now to 50 months, processing of laboratory samples step will be focused on study and selection of suitable processing technologies of latex film production. The pilot plan step aims at pre-industrialising materials production and processing for specific applications including SPADD device but also SSND, SDM etc. The work will consist in designing, manufacturing and testing.
