SIMAX glass, by its chemical composition and properties, belongs to the group of clear "hard" borosilicate glasses "3.3", with excellent high temperature and chemical resistance and low thermal expansion, defined by the international standard ČSN ISO 3585. It fully meets the properties prescribed by these standards. SIMAX glass is used to produce a wide range of technical and laboratory glass products, industrial apparatus and household cooking glass, which have become sought after in many countries around the world due to their properties and high utility value. Due to its properties, SIMAX glass is used where the highest demands are placed on products in terms of temperature and chemical resistance and neutrality towards substances or preparations that are in contact with them, i.e. in chemistry, petrochemicals, food, energy, metallurgy, healthcare, microbiology, pharmacy, mechanical engineering, laboratories. Products made of SIMAX glass are smooth and non-porous, perfectly transparent, catalytically indifferent, corrosion-resistant even in demanding operation up to 300°C without sudden temperature changes. SIMAX glass is very environmentally friendly and is completely harmless from an ecological point of view.
