Characteristics:
(1) these are safe products because of P.V.B film, the middle film. when the glass is broken, fragments of the glass are not scattered .
(2) In spite of adding the P.V.B film, the light transmission of the glass is as same as the flat board glass.
(3) It can be cut easily and processed aline.
(4) P.V.B film can be produced with various colors
(5) It can be used as quarium glasses
(6) These glasses are bullet proof and protecting from a thief.
Usage:
(1) for doors of the sky scrapers
(2) for places needed safety
(3) for show window; prevention from chmes
(4) for cars and trains (subway's windows)
(5) for boats and aquariums
(6) for places for keeping valuables.

In the production of flat glass the molten silica-based mix is cooled slowly under carefully controlled conditions. This annealing procedure removes undesirable stresses from the glass. Cooling occurs in an annealing "lehr"; hence, the glass is termed "annealed" or "ordinary" glass. Annealed glass which has been heated to a temperature near its softening point and forced to cool rapidly under carefully controlled conditions is described as "heat-treated glass." The heat treating process produces highly desirable conditions of induced stress (described below) which result in additional strength, resistance to thermal stress, and impact resistance.

Heat-treated glasses are classified as either fully tempered or heat strengthened. According to Federal Specification DD-G-1403B, fully tempered glass must have a surface compression of 10,000 psi or more or an edge compression of 9,700 psi or more. Heat-strength glass must have a surface compression between 3,500 and 10,000 psi, or an edge compression between 5,500 and 9,700 psi. The fracture characteristics of heat- strengthened glass vary widely from very much like annealed glass near the 3,500 psi level to similar to fully tempered glass at the 10,000 psi level.
