Thermoplastic and thermoset materials both fall under the broad category of Polymers. The biggest difference between a thermoplastic and thermoset is that a thermoplastic can be recycled. Whereas a thermoset irreversibly cure. Thermoplastic: PE, PP, PVC. Thermoset: Bakelite, Epoxy.
A Thermoplastic can be used for several things that require a certain temperature. For example one use of a thermoplastic could be to see the temperature of a liquid in a mug. Another use of thermoplastic could be used in the storage of foods to check what temperature it is being kept at.
Polyesters are a group of organic polymers that contain the ester functional group in their main chain. Polyesters can be either thermoplastic or thermoset, depending on the rest of their structure, but the most common polyesters are thermoplastic.
Wikipedia has an whole article on the topic thermoplastic extrusion. Thermoplastic extrusion is a high volume manufacturing process in which raw plastic material is melted and formed into a continuous profile.
the difference between thermosetting plastic and thermoplastic is thermosetting plastic is a plastic that can irreversibly cures the cure may be through heat) and thermoplastic is a type of plastic that can be vacuum formed. hope this helps you :)
Thermoplastic olefin is a plastic that helps absorb the energy from a crash or bump. And when you crash into something that is also made of thermoplastic olefin, it will bump back to you which will cause different forces. Like in Newtons first and third law of motion
