Feature
Weatherability
Forming
Forming temperature
Optical clarity
Cost
Duraplex
Excellent weatherability
with no impact or optical
property reduction
Better melt strength
No predrying required
Wide range (275°F-350°F)
Short cycle times
Very clear
Considerably less than poly-
carbonate
Polycarbonate
Yellows and less glossy when exposed
to sunlight, lessens impact strength
after exposure
Low melt strength
Often requires predrying
Distinct high forming temperature
Long cycle times, more energy cost
Less clear, hazy, shows distortion
Expensive
