Abstract

L'INVENTION CONCERNE UNE COMPOSITION DE MOULAGE ET DES PIECES MOULEES A PARTIR DE CETTE COMPOSITION. ON DISPERSE DANS UNE MATIERE POLYMERE A BASE DE STYRENE DES PARTICULES DE PTFE QUI PRESENTENT UNE DIMENSION GRANULOMETRIQUE PARTICULIERE ET SELON UNE PROPORTION DETERMINEE. LES OBJETS QUI SONT MOULES A PARTIR DE CETTE COMPOSITION THERMOPLASTIQUE RESISTENT BIEN A L'USURE ET AU FROTTEMENT ET IL EST POSSIBLE DE LES UTILISER DANS DES MILIEUX AQUEUX, PAR EXEMPLE DANS UN COMPTEUR A EAU.
