Abstract

See full text

A composition [composition (C)] comprising at least one poly(aryl ether ketone) polymer having a melt flow rate (MFR) equal to or higher than 8 g/10 min at 400.degree. C. and under a load of 2.16 kg, [(PAEKHMF) polymer], from 0.1 to 50 wt. % of at least one poly(tetrafluoroethylene) polymer having a D50 particle size equal to or below 10.mu.m, and having a melt viscosity equal to or lower than 1.times.105 Pas at 372.degree. C., from 0 to 50% wt. % of at least one poly(aryl ether sulfone) polymer having a melt flow of at least 15 g/10 min at 365 degree C. and under a load of 5.0 kg, [(PAES) polymer], from 0 to 50% wt. % of at least one reinforcing filler, with the proviso that—should the composition (C) comprise a (PAES) polymer having MFR of more than 22 g/10 min, then the (PTFE) polymer is present in an amount of less than 40 wt. %, and—should the composition (C) comprise a (PAES) polymer having MFR of 22 g/10 min or less, then the (PTFE) polymer is present in an amount of less than 30 wt. %, and wherein all % are based on the total weight of the composition (C).
