Clear float glass The clear float glass is made by high-quality sand, natural ores and chemical materials by mixing them and melting them at high temperature; The molten glass flow into tin bath where the float glass is spread, polished and formed on the molten tin. The float glass has smooth surface, excellent optical performance, stable chemical capability, and high mechanism intensity. It is also resistant to acid, alkali and corrosion. Features: 1) light transmittance >88%. 2) the thickness tolerance is controlled within± 0.1mm. 3) tolerance for glass in final cut sizes is controlled within ± 1mm. 4) the visible flaw is controlled strictly. The float glass has smooth surface Excellent optical performance, stable chemical capability and high mechanism intensity It is also resistant to acid, alkali and corrosion Package: seaworthy wooden cases with interlayer papers or powder HS Code : 7005 Float Glass and Surface Ground or Polished Glass, in Sheet Standard: Comply with china gb11614-1999, europe en 572, and russia gost 111-2001.
