1. Impact resistance

The maximum impact force of the endurance board can reach 3kg/cm, with a specific gravity of 1.34g/cm – sup3, which is 250-300 times
that of ordinary glass and 8 times stronger than acrylic board, with almost no risk of fracture.

2. Transparency

Excellent lighting, with a transmittance of up to 75-89%, and its transparency comparable to glass.

3. Weathering resistance

PC board can maintain the stability of various physical indicators within the range of -40 ℃ to 120 ℃ . The artificial climate aging test
lasted for 4000 hours, with a yellowing degree of 2 and a decrease in transmittance of only 0.6%.

4. Flammability

The endurance board itself is not flammable and has self extinguishing properties, as confirmed by the national standard GB50222 95. PC boards
are classified as Class 1 flame retardant, i.e. Class B1. The ignition point of the PC board itself is 580 degrees Celsius.

5. Heat resistance and cold resistance

Within the testing range of -30 ℃ to 130 ℃ , it will not cause quality changes such as deformation.

6. Sound insulation

The sound insulation capacity of PC board is 3-4DB higher than that of glass, making it the preferred material for highway sound barriers
internationally.
