How to determine type of plastic

WebThe deformation measures how much an object deforms from its original dimensions or size in a given direction. Depending on which deformation you measure, you can calculate different types of strain. A deformation is called elastic deformation if the stress is a linear function of strain. In other words, stress and strain follow Hooke’s law. WebTo initially determine whether a material is thermoplastic (meltable) or thermoset (non-meltable) type, heat a metal or glass stirring rod until it glows red or orange (to about 500°F / 260°C) and press it against the sample. If the sample softens, the material is a thermoplastic; if it does not, it's probably a thermoset.
