Will tempered glass cups break?

It will break. Tempered glass will break into pieces without acute angle under a certain external force, which will reduce the damage, but it will still break.

Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, compressive stress is usually formed on the surface of glass by chemical or physical methods. When the glass bears external force, the surface stress is first offset, which improves the bearing capacity and enhances the wind pressure resistance, cold and heat resistance and impact resistance of the glass itself.

Tempered glass cups are safe to use, and the increase of bearing capacity improves the fragility. Tempered glass is a small fragment without acute angle even if it is damaged, which greatly reduces the harm to human body. Compared with ordinary glass, the quenching and heat resistance of tempered glass is improved by 3~5 times, and it can generally withstand the temperature difference of more than 250 degrees, which has obvious effect on preventing hot cracking.

Classification of glass

1, structural classification

Glass is divided into double-layer glass and single-layer glass, and the production process is different. Double glazing mainly meets the needs of advertising cup, and the inner layer can be printed with the company's logo, promotional gifts or gifts, which makes the insulation effect more prominent.

2. Classification of materials and uses

Crystal Cup, Glass Office Cup, Glass Mouth Cup, Cup with Tail and Cup without Tail. The heat preservation time of the tail cup is not as short as that of the thermos cup. The tailless cup is a thermos cup with long heat preservation time.
