Impact Resistance.
Of all glazing materials polycarbonate exhibits greatest resistance to impact over a temperature range of –20 to +100oC. It is approximately 200 times more resistant to impact than glass.

The impact test illustrated demonstrates the impact resistance of MARLON FS Longlife.

A striker of diameter 16 mm contacts a sample of sheet placed on a support ring with an inner diameter of 38 mm. A weight of 1.8 kg is dropped on to the striker from a height of 1.5 m. The resulting impact energy of 27 Nm only dents the sample, it does not crack or penetrate.
