Low friction systems and devices |
| 摘要 |
Disclosed herein are compositions and systems having a low coefficient of friction. The low friction system comprises a first surface and a second surface, where the first surface comprises (i) a polycarbonate and a first additive, or (ii) a polybutylene terephthalate and a second additive; and the second surface comprises a polyoxymethylene and a third additive. The low friction compositions and systems are valuable for producing devices, such as medical devices. |

1. A device comprising a first solid component in frictional surface contact with a second solid component,
wherein the first solid component consists of a polybutylene terephthalate and silicone oil, wherein the second solid component consists essentially of a polyoxymethylene, and wherein friction at the surface contact due to relative motion in any direction between the first and the second components is less than or equal to about 0.06, when measured using a contact pressure of 3 MPa and a sliding speed of 0.02 meters per second. |
