☆ Ultra clear tempered glass is produced by heating annealed glass in a furnace to 620℃. Progressing from the furnace, the glass is rapidly cooled with jets of cold air, inducing compressive stresses to the surface while the center remains tensile.
☆ 4-5 times stronger than annealed glass of the same thickness.
☆ Stronger resistance to thermal breakage than annealed or heat strengthened glass
☆ If breakage occurs the glass breaks up into small, cubical fragments, which are not threatening to humans.
☆ Suitable for use as a safety glass as defined by consumer product safety association 16CFR 1201, ansiz 97.1 1984 and BS6262.
☆ Conforms to CCC, AS/NZS2208-1996, EN12150-1, and ASTM C1048. All work done on glass
(beveling, cutting, bending, etc) must be done before tempering.
