CA 2545735

A method of improving the wear resistance of a polymer is disclosed comprising the steps of evenly dispersing an ultrafine inorganic particulate material in the polymer at a loading rate of 0.01 to 20wt% of the total weight of the particulate polymer composite. The mixing or dispersing is preferably carried out under sub-atmospheric pressure conditions to ensure little or no bubbles form in the mixture prior to curing.

L'invention concerne un procédé d'amélioration de la résistance à l'usure de polymère, par dispersion uniforme de matériau particulaire inorganique ultrafin dans le polymère à un taux de charge compris entre 0,01 et 20 %, par rapport au poids total du composite polymère particulaire. De préférence, on conduit le mélange ou la dispersion en pression sub-atmosphériq ue pour assurer une présence faible ou une absence de bulles dans le mélange avant le traitement.
