PC – Polycarbonate (optical grade)

PC

Polycarbonate sheet is a thermoplastic with excellent impact strength, good heat resistance, and excellent mechanical strength within the temperature range of -50 to 120 °C. Products made from polycarbonate sheets include safety goggles and glazing for forestry machines, excavators, and tractors. It is also an excellent glazing material for private and public premises at risk of vandalism. The weak point of polycarbonate is its low resistance to solvents (with the exception of coated polycarbonate sheets). We offer PC as plastic sheets.
