High stress glass, usually referring to tempered glass, is formed by special physical or chemical treatment methods to create a compressive stress layer on the surface of the glass and a tensile stress layer inside. This stress distribution enables glass to quickly release energy and form uniform small particle fragmentation when impacted, thereby improving its safety and strength.
High borosilicate glass is a special type of glass, whose main components include a high proportion of boron and silicon. This type of glass has extremely high heat resistance, good chemical stability, and excellent mechanical strength. It is commonly used in environments that require resistance to high temperatures and chemical corrosion.
Tempered glass is usually manufactured using quenching method. After heating ordinary glass to the softening temperature, it is rapidly cooled to harden the surface and form a compressive stress layer. This method significantly improves the strength of glass.
The production process of high borosilicate glass is more complex. It requires melting raw materials such as borax and silica at high temperatures, and undergoing precise formulation and strict temperature control. This process ensures the high heat resistance and chemical stability of the glass.
Strength: 4-5 times higher than ordinary glass.
Safety: When broken, small particles are formed to reduce harm to the human body.
Heat resistance: Limited heat resistance range, usually suitable for room temperature environments.
Heat resistance: can withstand high temperatures of up to 1000 ° C.
Chemical stability: Excellent acid resistance, alkali resistance, and salt corrosion resistance.
Mechanical strength: higher than ordinary glass and tempered glass.

Although tempered glass has high strength, it may explode at high temperatures. Its fire resistance mainly depends on its high strength and safety during breakage, but its structural stability is limited in extreme high temperature environments.
High borosilicate glass performs well in high-temperature environments due to its excellent heat resistance. It can withstand prolonged exposure to high temperatures without breaking or deforming, making it more advantageous in fire protection applications.
The production cost is low and the market price is relatively affordable. Widely used in daily life and the field of architecture.
The complex production process and high raw material costs result in higher market prices. Mainly used in professional fields with high performance requirements.
The energy consumption is high during the production process, but the waste is easy to recycle and reuse.
The energy and resource consumption during the production process is relatively high, but due to its excellent performance and long service life, the overall environmental impact is relatively small.
Overall, although tempered glass performs well in daily applications, high borosilicate glass has more advantages in terms of fire resistance due to its excellent heat resistance and structural stability. Therefore, in situations where high-performance fire-resistant materials are needed, high borosilicate glass is a more ideal choice. Through the above multi angle analysis, we can clearly see the differences in characteristics, applications, and fire resistance between high stress glass (tempered glass) and high borosilicate glass. The choice of glass depends on specific usage requirements and environmental conditions.
