  • Capstan comprising polyacetal-based polymer composition for magnetic tape cartridge
    Patent number: 5854330
    Abstract: The invention relates to a method for preparing a polyacetal-based polymer composition with a high impact strength comprising 35-96.5 wt. % of a polyacetal component, 3-40 wt. % of a polyurethane component and 0.5-20 wt. % of a carbon black component with all percentages referring to the mass of the polymer composition, wherein the polyurethane component and the carbon black component are compounded prior to adding the polyacetal component, and the polyacetal-based polymer composition obtainable by such method. The invention further-more relates to a capstan or drive roller for a magnetic tape or data cartridge comprising a polyacetal-based polymer composition which comprises 35-96.6 wt. % of a polyacetal component, 3-40 wt. % of a polyurethane component and 0.5-20 wt. % of a carbon black component with all percentages referring to the mass of the polymer composition.
