  • Thermosetting resin stationary tape guides for magnetic tape cassettes
    Patent number: 4821135
    Abstract: A tape guide for magnetic tape cassettes, comprising a thermosetting resin composition, such as a polyester resin having a glass transition point of not lower than 100.degree. C. containing an inorganic filler such as silicon powder and, optionally, a resin powder such as a tetrafluorethylene resin powder in a proportion of from 60 to 75% by weight based on the total composition. The tape guide has an increased thermal conductivity of 10.times.10.sup.-4 cal/cm.deg.sec or more and a low coefficient of friction and is, therefore, free from undesirable frictional heat generation.
