a. Visually examine the sample, looking for recycle codes
b. Try assessing the flexibility by bending, and look at the bending zone
- does the material stretch or is it brittle?
c. Test the hardness, try scratching it with pencils of differing hardness
( B,HB,1-6H ) to ascertain which causes a scratch in the plastic.
Alternatively, attempt to scuff the sample with a fingernail.
d. Cut a small slither with a sharp knife. Does the sample cut cleanly
( thermoplastic )?, or does it crumble ( thermosetting )?
e. Hold sample in small flame, note whether it burns, self-extinguishes on
removal from the flame, colour of the flame, and smell/acrid nature of
fumes when flame is blown out ( Caution - the fumes are likely to be
toxic ). Also attempt to press melted sample against a cold surface, and
pull away - does sample easily form long threads.
f. Drop onto a hard surface, does the sample "ring" or "thud"?
g. Place it in water. Does it float, sink slowly, or sink rapidly?
If it sinks rapidly, it is likely to be halogenated ( PVC, Viton, PTFE )
If it sinks slowly, possibly nylon
If it floats possibly polyethylene or polypropylene.

Are plastic cups organic or inorganic?
Plastic cups are considered inorganic as they are derived from synthetic materials like polymers. Organic compounds are typically associated with living organisms and contain carbon-hydrogen bonds. Plastic, being a man-made material, is not classified as organic.
Does plastic catch fire?
Anything can burn, except for stars. Plastic is one of the easiest things in the world to burn. Though it does give off quite a smelly odor when burned. (though it's actually more pleasant smelling than the burning of rubber)

Is polythene classified as plastic?
Yes，Plastics can be classified by chemical structure, namely the molecular units that make up the polymer's backbone and side chains. Some important groups in these classifications are the acrylics, polyesters, silicones, polyurethanes, and halogenated plastics. Plastics can also be classified by the chemical process used in their synthesis, such as condensation, polyaddition, and cross-linking.
