Abstract
The invention relates to polyacetal compositions comprising a mixture of (i) a polyacetal resin, (ii) p-aramid particles and (III) a vinyl-terminated dimethyl siloxane polymer. These compositions are useful in preparing molded articles exhibiting a good balance between high self-lubricating properties and wear resistance, and especially useful in articles that are in motion with respect to other parts they are in contact with.
