Delrin/Acetal (Polyoxymethylene) vs Acrylic/Lucite/PlexiGlass (polymethyl methacrylate) vs Lexan (Polycarbonate)
I work with Delrin, Acrylic, and Lexan alot and been trying to find strengths and weakness of the three types of plastics. Since plastics are all slightly different depending on it's use and make, I was wondering if the below is a good general assumption of the three:
Hardness
Acrylic > Delrin > Polycarbonate
Density
Delrin > Acrylic > Polycarbonate
Transmittance (Clearity)
Acrylic > Polycarbonate > Delrin
Refraction (Reflection)
Polycarbonate > Acrylic > Delrin
Yellowing (Yellowing Due to UV)
Polycarbonate > Acrylic > Delrin
Chemical Resistance
Delrin > Acrylic > Polycarbonate
Thermal Expansion (Retains Shape as Heated)
Delrin > Polycarbonate > Acrylic
Tensile Strength (Pull until break)
Polycarbonate > Delrin ~ Acrylic
Flex Strength (Bend until break)
Acrylic > Delrin > Polycarbonate
Compression Strength (Crush until break)
Delrin > Polycarbonate > Acrylic
Shear Strength (Tear until break)
Delrin > Polycarbonate > Acrylic
Modulus of Elasticity (Rigidity)
Delrin > Acrylic > Polycarbonate
Coefficient of Friction
Acrylic > Polycarbonate > Delrin
Corrections and additional plastics or comparisons are appreciated.
