What is the life span of polycarbonate sheet? How do UV rays affect it?
A. A 10 year warranty is the industry standard for polycarbonate sheet products though the working life is normally considerably longer. Actual performance depends on individual applications and local environmental factors, but 20 years and over is now becoming common. Most thermoplastic materials do suffer slow deterioration as a result of UV exposure, usually this initially manifest itself in a gradual yellowing of the sheet rather than a reduction in the mechanical properties. Build ups of moss and dirt will also lead to lower levels of light transmission and thus a lowering of performance.
