Composite Material Based On Polyamide And Submicronic Mineral Particles



Published September 12, 2006
Related Searches: composite
Composite material comprising a matrix based on polyamide and mineral submicron particles has been patented. The polyamide is obtained by polycondensation of a diamine with a dicarboxylic acid. The particles comprise a silica-based core and an at least a discontinuous layer of an oxide, hydroxide or hydrated oxide of zirconium, whose isoelectric point is greater than that of the core. The particles are free of a silane coupling agent.
