PCT numbers PCT/DE94/00007 seconds. 371 conclude the age of second on the 24th July in 1995. 102 August 4th PCT publication numbers on January 7 WO94/17004 PCT publication dates of 1995 (e) date PCT 1994 on July 24 submit, the method that 1994In is used to generate the insulating materials of the bound control with environmental protection, one long chained starch is used as adhesive, in addition to silicone. Starch is heated up to 50 degree to 60 degrees Celsius, keeps in this temperature and respectively sprays on the glass fibers from silicone; It is made of using 6 to 8% adhesive starch and silicone, then one pulls into Filamentous glass mat or slab and can be shaped and dry at about 180 degrees Celsius. One to pull into Filamentous glass mat (16), insulated target or slab or absorber be that thus obtained its surprisingly waterproof and is uniquely combined, resin and silicone by starch, can unquestionably using and always with a uniform bulk density. It is providing in that purpose plant (1), providing for water (9), for starch (10) and for the supply ring of silicone (11). Nozzle (13) for supply ring 10 has large opening and separation edge. Premixing container (17) and feed pipe (15) are heatable or heat-insulated. In another embodiment, a latex is made of silicone resin, silicone oil, a dust binder and starch, is atomized and is sprayed to 200 degrees Celsius at 18 degree on the stream of the process of glass fibre.
