Under the trademark SIMAX, the borosilicate glass produced by Sklarny Kavalier is registered. In 1837, the factory with the longest history in the technical glass industry was established. The Sklarny Kavalier company, as early as in the 1930s, was the first to make attempts to manufacture borosilicate glass. Gradually, there was a dynamic technological development, especially in the years 1950-1980. Thanks to achieving the right technological level and comprehensive know-how, Kavalier is one of the leading producers of technical glass, pressed and blown products for domestic use and glass pipes. Simax glass produces a large number of glassware, industrial appliances and brewing glass. They are products valued all over the world due to their properties. It meets the highest requirements in terms of temperature and chemical resistance, neutrality to preparations found in the medical, food and energy industries, microbiology, pharmacy and metallurgy. The surface of SIMAX glass products is smooth, non-porous, corrosion-resistant and homogeneous. The high resistance of SIMAX to sudden changes in temperature is achieved by a low coefficient of linear thermal expansion, a low elastic tensile force and relatively high thermal conductivity.
