Abstract
A self-lubricating polymer composition is provided. The self-lubricating composition comprises a polymer matrix formed from a homopolymer or copolymer selected from the group consisting of a polyamide, a polyester, a polycarbonate, and combinations thereof, and a particulate siloxane slip agent substantially homogeneously distributed in the polymer. Also provided are self-lubricating articles, such as electrical wire and optical cable, coated with the self-lubricating polymer composition.
Claims18
A self-lubricating polymer composition, the composition comprising:
- a polymer matrix formed from a nylon;
- and
- a particulate siloxane slip agent substantially homogeneously distributed in the polymer,
- wherein the siloxane concentration is between about 0.05 percent by weight and 1 percent by weight based on the total weight of the polymer and siloxane, the average particle size of the particulate siloxane is from about 0.5 μm to about 25 μm.
