Excellent toughness even at low temperatures. Not susceptible top stress cracking. Limitations are that natural polymer base causes greater variations in properties than truly synthetic polymer. Tendency to creep under load. Almost unlimited color range- transparent, translucent and opaque.
Limitation is that optical properties are inferior to acrylics.
No dust attraction as a result of electrostatic pickup. Good grease resistance. Limitations are that it is attacked by strong acids and alkalis. Dissolved or swollen by alcohols, esters, ketones, aromatic and chlorinate hydrocarbons. Permeable to water vapor and gasses in varying degrees.
