Explained: Can Bulletproof Glass Use In Phones?

if you have a phone so you buy a back cover and tempered glass to protect your phone from screen or body damage but do you ever think why the phone company doesn't use bulletproof glass to protect the phone.

Can we install bulletproof glass in phones? 

tomorrow when I use my phone I was thinking that why normal phones don't have a bulletproof glass if you don't know what is bulletproof glass I tell you a bulletproof glass is a type of glass but its so strong even bullet can't pass through it away. interesting but where the bulletproof glass used  Bulletproof glass is used in windows of buildings that require such security, such as jewelry stores and embassies, and of military and private vehicles. 

so now I think you know a lot about bulletproof glass and if you want to know more you can click here for more and deep information so now let us know how bulletproof glass made I was also thinking how can a glass stop a bullet I tell you a bulletproof glass is not an only glass it is a collaboration of glass and polycarbonate layer by layer and polycarbonate makes bulletproof glass flexible and easy to band it okay let me goes some deeper now you are thinking what is Polycarbonate. Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed (source Wikipedia). the polycarbonate used in many electrical appliances because polycarbonate is a good insulator of current and heat-resistant  

Most important question? 

Okay now you know a lot about this glass but why they didn't use it in making phone screen first bulletproof glass made by many layers of glass and polycarbonate and it becomes so thick if you are thinking how much thick it doubles thicker than your phone so the screen doesn't work and the phone becomes so heavier and the sensors of the phone won't work normally like before, phones become heavier and non-convenient for use in daily life and you cant play games. And bulletproof glass is not much bendable as normal glass and it's not suitable for flip screen phones.

Environmental effects 

The properties of bullet-resistant glass can be affected by temperature and by exposure to solvents or UV radiation, usually from sunlight. If the polycarbonate layer is below a glass layer, it has some protection from UV radiation due to the glass and bonding layer. Over time the polycarbonate becomes more brittle because it is an amorphous polymer (which is necessary for it to be transparent) that moves toward thermodynamic equilibrium.

An impact on polycarbonate by a projectile at temperatures below −7 °C sometimes creates spall, pieces of polycarbonate that are broken off and become projectiles themselves. Experiments have demonstrated that the size of the spall is related to the thickness of the laminate rather than the size of the projectile. The spall starts in surface flaws caused by bending of the inner, polycarbonate layer and the cracks move “backward” through to the impact surface. It has been suggested that a second inner layer of polycarbonate may effectively resist penetration by the spall

 

Which glass is most durable?

Gorilla glass is the most durable glass yet it can protect your phone from scratch and a little bit of dent.
