Tempered glass, semi-tempered glass is the ordinary glass heating and cooling treatment after the glass surface has a strong uniform compressive stress, mechanical strength exponentially increased glass. The surface compressive stress of tempered glass is above 90MPa, and the surface compressive stress of semi-tempered glass is between 24-52MPa.

Toughened glass features

◆ Safety: glass broken into honeycomb like small obtuse particles, will not cause significant harm to the human body.

◆ High strength: the strength of tempered glass is 4 ~ 5 times that of ordinary glass.

◆ Deflection: 3 ~ 4 times larger than ordinary glass.

◆ Thermal stability: tempered glass has good thermal stability, can withstand the temperature is 3 times that of ordinary glass, can withstand the temperature difference of 300℃.

Semi-tempered glass features

Semi-tempered glass is also called thermal reinforced glass or reinforced glass, it and tempered glass surface compressive stress difference, its mechanical strength is 1.6 to 2 times of ordinary annealed glass, has good thermal stability. The degree of smoothness and transmittance of semi-tempered glass can be closer to ordinary annealed glass and is far better than tempered glass. Its Z big advantage is that there is no self-explosion.

Toughened glass for use

Widely used in places with high mechanical strength and safety requirements. Such as: glass doors, building curtain walls, facade Windows, indoor partition and close to the heat source and by hot and cold impact more intense position partition.
