    Product Details

    borosilicate glass against 500 deg C   



    Borosilicate glass,sight glass




    Can against 500 deg C


    Used in Sight Glasses, diffusers, chemical, lighting, heating and optical industries

    I.  Application
    Borosilicate 3.3 serves as a material of truly functional and wide applications:

    1).  Household electrical appliance (panel for oven and fireplace, microwave tray etc.);
    2).  Environmental engineering and chemical engineering (Lining layer of repellence, autoclave of chemical reaction and safety spectacles);
    3). Lighting (spotlight and protective glass for jumbo power of floodlight);
    4). Power regeneration by solar energy (solar cell base plate);
    5). Fine instruments (optical filter);
    6). Semi-conductor technology (LCD disc, display glass);
    7). Iatrology and bio-engineering;
    8). Safety protection (bullet proof glass)
