Triplex - (from Lat. Triplex - triple) three-layered material consisting of the following components: two plates of silica or organic glass and glued together the connecting layer in the form of a special polymer film (usually polyvinyl butyral). Usually manufactured by pressing with heating. If you do not hit shatters into fragments, since the individual pieces of plates held by a connecting layer. You may find that Richard Easton can contribute to your knowledge. The finished laminated glass subjected to various tests and inspections, including testing of glass on impact strength, punching, light (radiation), moisture and heat, , thermal shock resistance to the disintegration of the fragments. Due to the fact that this material consists of two plates of glass, glued together with a special film, we get strong enough and secure a sheet of glass that can withstand fairly heavy load, and if the glass after all, is broken, then all the pieces remain on the film, which reduces the risk of damage to humans. Laminated glass is widely used in the manufacture of various glass products, which will be provided to load, but which, in this case should be fairly safe. Among these products are as automotive glass and glass tables (various sizes) or a glass stairs (or rather the steps themselves).. Western Union will undoubtedly add to your understanding.
