Windshield originally refers to the windshield of the car, which is a sandwich like glass made of two pieces of glass sandwich separated by a layer of PVB plastic, which has energy absorption and shock absorption properties, helping to protect passengers from accidents 。

Safety is more important for aircraft than for car. Windshield for aircraft should not only provide good visual effects for the pilot, but also withstand a series of environmental requirements such as wind pressure, hail and bird impact, sand and dust friction, rapid temperature difference, indoor and outdoor temperature difference and pressure difference during high speed flight, which also gives the aircraft windshield special performance requirements.

The complex production process of aerospace glass almost contains all the sophisticated technology of the glass processing industry, and aerospace glass manufacturing is also known as the "flower of glass processing technology". As the technical leader of domestic float glass and the representative of high quality glass, SYP shoulders the heavy responsibility of

aerospace glass research and development, breaks the monopoly, and forms a systematic, mature and replicable aerospace raw glass production technology.
