Bullet Proof principle
When a high-speed bullet impacts on the bulletproof glass , the hitting position of the glass breaks and forms a radial shape , but the bullet head will be deformed . The kinetic energy of the bullet will be reduced and absorbed .The kinetic energy of the bullet will be reduced and absorbed make it impossible to penetrate the glass , while the glass pieces are stuck , making it difficult to spatter and injure others .
Financial system , museums , postal services , and insurance systems , it is also suitable for places with high safety requirements such as high-end villas and business buildings .
