The technical plastic polycarbonate meets the highest requirements in terms of brilliance and impact strength. The continuous operating temperature of 90°C, and even up to 140°C for short periods, means that it can also be used under extreme climatic conditions and fitted with high-performance lamps.
This is why Elkamet manufactures the shades exclusively from polycarbonate.
PC is crystal clear and is characterised by good chemical resistance. The high impact strength is maintained even in extreme cold, down to -40°C.
