  • Aqueous medium of a water insoluble additive for mineral fiber insulating materials
    Patent number: 5217529
    Abstract: Insulating materials consisting of artificial mineral fibers are impregnated with water insoluble additives, e.g. dust binders and/or water repellant finishing agents in that they are wetted with an emulsion of the water insoluble additive in an aqueous solution of a cellulose ether. Impregnation takes place easily and is effective and resistant.
    Type: Grant
    Filed: May 25, 1990
    Date of Patent: June 8, 1993
    Assignee: Isover Saint-Gobain
    Inventors: Hartmut Tiesler, Joseph Schirmeisen
  • Glass fibers decomposable in a physiological medium
    Patent number: 5108957
    Abstract: Glass compositions useful for forming fibers which are readily able to be degraded in a physiological medium such as that found in a human body. Advantageous compositions formed according to the present invention comprise the following components, set forth in percent by weight:SiO.sub.2 : 57 to 70%Al.sub.2 O.sub.3 : 0 to 5%CaO: 5 to 10%MgO: 0 to 5%Na.sub.2 O+K.sub.2 O: 13 to 18%B.sub.2 O.sub.3 : 2 to 12%F: 0 to 1.5%P.sub.2 O.sub.
