Sunny Group has offered glassware since 1992 with all kinds of products being exported to more than 30 countries and regions.I believe that we often come into contact with high borosilicate glass material household products in life, so what is high borosilicate glass in the end, next let Sunny glassware take you to understand the knowledge of high borosilicate glass:

  • What is high borosilicate glass

High borosilicate glass is sodium oxide (Na2O), boron oxide (B2O3), silicon dioxide (SiO2) as the basic composition of a kind of glass, expansion coefficient of 3.3±0.1×10-6/K, also known as "3.3 borosilicate glass". The composition of the glass is high in borosilicate content, boron: 12.5~13.5%, silicon: 78~80%, so it is called high borosilicate glass. High borosilicate glass material is mostly designed for cups, teapots and so on.The simple and generous double-layer cup designed by The Sunny glassware design team is shown in the picture below.Sunny glassware Award-winning team of designers has won the trust of many upscale brands like NEST Fragrance. The talented design team is unmatched in China.

  • The process of high borosilicate glass

The process of high borosilicate glass is generally divided into two categories: manual blowing and furnace pressing; Manual blowing is a common double-layer cup in Sunny glassware. Manual blowing process: purchasing tube -- cutting tube -- bottom burning -- manual blowing forming -- mouth burning -- assembly -- sticking accessories -- mouth plugging -- annealing. The abrasive tool consists of 1 Abrasive tool + bottom mold (movable mold, the product can rotate in the mold) 2 Dead mold (with complex shape, the product can not rotate in the mold, and there are patterns). The abrasives are made of graphite mould cast iron mould.

  • High borosilicate glass does not contain heavy metal substances

    The main components of high borosilicate glass are boron and silicon, in which the content of boron is 12.5-13.5% and the content of silicon is 78-80%, so the acid resistance and alkali resistance of high borosilicate glass are also very superior. Therefore, high borosilicate itself does not contain toxic substances. At the same time, high borosilicate's high temperature resistance, acid resistance and alkali resistance can make high borosilicate not easy to precipitate harmful substances in daily drinking water use.
