With the improvement of people's quality of life and the deterioration of haze weather, the demand for multifunctional screen windows such as environmental protection and dust prevention and haze prevention will increase.

The core technology of screens lies in screens.

Properties of PP: PP is a crystalline polymer. Among the commonly used plastics, PP is the lightest, with a density of only 0.91g/cm3. Among general plastics, PP has the best heat resistance, and its heat distortion temperature is 80-100°C. Boiled in boiling water, the embrittlement temperature is -35℃. Embrittlement will occur below this temperature, and the cold resistance is poor. PP is very sensitive to ultraviolet rays and not resistant to ultraviolet aging, so it will decompose after being irradiated by ultraviolet rays.
