Borosilicate glass, Environmentally Friendly Manufacturing

Entering the product exhibition hall of Honghua Company under Yaohua Group, a dazzling array of high borosilicate special glass and application products are dazzling. After years of research and development, the company’s leading product is high borosilicate glass, because the linear thermal expansion coefficient is (3.3 ± 0.1) × 10-6/K, called “borosilicate 3.3 glass”. It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Because of its excellent performance, it is widely used in household appliances, environmental engineering, medical technology, safety protection and other fields, making it a “sweet cake” favored by the market.


As a national high-tech enterprise, Honghua always adheres to the concept that scientific and technological innovation is the first productive force. Give play to the technical advantages of the Borosilicate Center, actively explore new fields such as the full electric melting float process of low expansion coefficient borosilicate glass, the full electric melting float process of borosilicate fireproof glass, the full electric melting float production process of large tonnage borosilicate glass, and the exploration of the toughening technology of borosilicate glass, and obtain 22 utility model patents and 1 invention patent through independent research and development.
The company focuses on technological innovation and green development. The full electric melting technology is adopted, and its main energy is clean energy, reducing the dependence on traditional fossil fuels; The energy saving technology of vertical cold roof and low-temperature forming with completely independent intellectual property rights is adopted to effectively reduce energy consumption.


The company has continuously promoted technological innovation and expanded its leading products from borosilicate 3.3 to borosilicate 4.0 and borosilicate fire-proof glass. The borosilicate fire-proof glass has passed the authoritative testing of the national standard testing authority. The single piece of borosilicate fire-proof glass with the thickness of 6mm and 8mm still maintains the integrity of the glass after the fire exposure time reaches 180min, reaching the level of advanced products of the same kind abroad.
