ABSTRACT:
Compositions and materials for use in load/unload ramps in magnetic disk drive assemblies are disclosed, particularly compositions or materials to improve at least one of the desired characteristics of low wear, low cost, high mechanical stability and high moldability. Thermoplastic polymers, such as acetal homopolymers, acetal copolymers, polyetherimides, polyphenylene sulfides, and polysulfones, are combined with other compositions, such as polyaramides, to improve the characteristics of a load/unload ramp constructed therefrom. Additionally, another material may be added, such as a polytetrafluoroethylene or perfluoropolyether.
