Polycarbonate surfaces have similar properties with regard to thermal and mechanical loads as protective surfaces made of glass.

Advantages of Polycarbonate Surfaces

Very sturdy

Polycarbonate - surfaces are highly resistant to mechanical stress and do not create splinters in case of damage. As a result, they are preferably used in applications that are at risk of vandalism, such as kiosk systems, or in applications such as handhelds, which can often fall to the floor and therefore require a robust and splinter-free protective surface.

Highly heat-resistant

Another advantage of polycarbonate surfaces is the very high temperature resistance. They can be used in temperature ranges from -90°C up to +135°C without being damaged. This means that they even exceed the temperature tolerance of borosilicate glass.

High optical quality

While almost all thermoplastics have only limited optical quality, polycarbonate has excellent optical properties and a high level of transparency that is retained for a very long time.

Disadvantages of Polycarbonate Surfaces

Polycarbonate has only limited resistance to chemicals or cleaning agents. Frequent contact leads to the surface being attacked and the optical quality and transparency of the material being impaired.

"PCAP touchscreens with polycarbonate surfaces are not suitable for use in cleaning-intensive environments or for hospital applications where equipment is permanently exposed to strong cleaning agents. This is where we offer our customers alternatives." Christian Kühn, Glass Film Glass Technology Expert
In addition, continuous loads above 20 Mpa or high dynamic loads on the surface can lead to breakage of the surface.
