Polycarbonate sheet is a solid panel produced by melting and extruding polycarbonate pellets, with a general thickness ranging from 1 mm to 18 mm. Thanks to the inherent properties of polycarbonate, it features excellent flame retardancy, light transmittance, and temperature adaptability. Compared with other sheets, it has more outstanding advantages, especially superior impact resistance.
One may ask: How strong is the impact resistance of polycarbonate sheet? Let’s look at the data:
The impact strength of polycarbonate sheet is 250–300 times that of ordinary glass, 30 times that of acrylic sheet of the same thickness, and 2–20 times that of tempered glass. These figures are remarkable.
For a clearer comparison, tests were conducted using sheets of the same thickness placed on the ground and impacted by hammers dropped from a height of 2 meters. The maximum bearable weight is as follows:
- Laminated glass: 0.02 kg
- Acrylic sheet: 0.2 kg
- Tempered glass: 3 kg
- Polycarbonate sheet: 6 kg
Although not highly precise testing, it is clear that polycarbonate sheet is an excellent choice for applications requiring high impact resistance in outdoor environments.
With these properties, polycarbonate sheet is widely used in:
road sound barriers, basketball backboards, police riot shields, explosion-proof glass, and even transparent viewing panels in large aquariums.
Besides impact resistance, polycarbonate sheet also offers flame retardancy, temperature resistance, anti-aging performance, light weight, and flexibility, opening up broad application possibilities. It can be expected that polycarbonate sheet will become increasingly common in daily life.
