The present invention therefore relates to a composition comprising: A) 100 parts by weight of a thermoplastic resin (A); and B) at least 0.5 part by weight of a siloxane blend (B) consisting essentially of 50-99 % by weight of the siloxane blend of a high molecular weight siloxane having a viscosity of greater than 60 Pa.s and 1-50 % by weight of the siloxane blend of a low molecular weight siloxane having a viscosity of 10 to 330 Pa.s, wherein said high molecular weight siloxane has a viscosity greater than the viscosity of said low molecular weight siloxane. These compositions exhibit surprisingly improved properties, such as having reduced coefficient of friction, consistent coefficient of friction over time, increased hydrophobicity and improved abrasion resistance. |
