Polymer
Type
Thermoplastic
Advantages
Outstanding weathering and resistance
to UV radiation. Transparent. High
gloss and hardness. Good rigidity.
Dimensionally stable. Good abrasion
resistance - surface scratches can
be polished out.
Disadvantages
Not a tough material in comparison
with engineering plastics, notch sensitive
and generally brittle. Although not
attacked by alcohol alone, alcohol
with carbon tetrachloride and ether
will cause swelling. Dissolved by
most aromatic and chlorinated hydrocarbons.
Water absorption is low but can have
a considerable effect on dimensions
and a lesser one on mechanical properties.
