BOROSILICATE GLASS FEATURE
High borosilicate glass material is mainly made of SiO2,B2O3,Al2O3 etc.High borosilicate glass itself have scratch resisitant. High borosilicate glass coefficient of thermal expansion is 3.7~3.8.These raw material can make high borosilicate glass withstand high and low temperature. The high and low thermal shock is up to 130C. High borosilicate glass is Microwave safe,Dishwasher safe,Freezer safe. Oven safe safe temperature can be up to 520C. Heat-resistant high borosilicate glass is a special glass material with low thermal expansion,the main glass-forming constituents silica and boron trioxide,high temperature resisitance,abrasion resisitance,acid and alkali resistant,high strength,high hardness and high chemical stability. Due to its excellent property,it is widely used in daily necessaries,kitchen bakeware,lab glassware and high-temperature industry glassware. The borosilicate glass produced by our company in the SGS test shows the contents of cadmiun and plumbum are both lower than 0.5PPM, far below the 20PPM required by the European standard ROSH,which is recognized as a green EP product by every country in the world.
