Question

conclusion of identifying thermoplastic and thermosetting plastics by flame test.​

Answer 1

Answer:

To initially determine whether a material is thermoset or thermoplastic, heat a stirring rod (to about 500° F) and press it against the sample. If the sample softens, the material is a thermoplastic; if not, it is probably thermosetting. Next, hold the sample to the edge of a flame until it ignites.
