The Sabic Global Technologies B.V. patent solves the following problem:
Ultra-high molecular weight polyethylene (UHMWPE) has a very high melt viscosity that makes conventional processing techniques such as screw extrusion and injection molding difficult to fulfill. Thus, the use of UHMWPE limited. Polyetherimide (PEI), and polyetheretherketone (Peek) is used in a variety of lubricated applications such as gears, bearings, and rollers, for example.
Our analysis of this patent is as follows:
Sabic Global Technologies B.V.’s patent US 9181430 B2 deals with Wear and friction properties of engineering thermoplastics with ultra-high molecular weight polyethylene.
Said here is the composition comprising a polymer comprising polyetherimide, polyetheretherketone, polyamide, polyoxyalkylene or polyalkylene terephthalate, or a mixture thereof, and ultra-high molecular weight polyethylene, where the ultra- high molecular weight polyethylene covers a surface modifier. Also disclosed are articles containing one or more of the species composition. abstract It is intended as a scanning tool for purposes of searching in the particular art and is not intended to limit the present invention.
