1, high borosilicate is a very strong and heat-resistant glass material. The weight is much lighter than traditional glass, but it is more durable than ordinary Shi Ying glass.

2. High borosilicate glass uses boron to replace silicon oxide in traditional glass. Boron plays a role in bonding silicate. Because boron is a smaller particle, it can be condensed more closely together, thus forming a harder borosilicate glass.

Therefore, double-layer glasses are lighter, thinner, brighter and stronger than ordinary glasses.

4, but because of the high cost, it is usually only suitable for scientific research and military equipment.
