Question

polythene is a thermoplastic whereas melamine is a thermoset.compare their structures and designs. how do their properties depend on their structures

Answer 1

denoting substances (especially synthetic resins) that become plastic on heating and harden on cooling, and are able to repeat these processes.

Answer 2

Answer:

Introduction - Thermoset vs Thermoplastic

Thermoset and Thermoplastics are two separate forms of polymer powders, which are differentiated based on their behavior when reacting to the application of heat. The primary difference between the two is that Thermoset is a material that strengthens when heated, but cannot be remolded or heated after the initial forming, while thermoplastics can be reheated, remolded, and cooled as necessary without causing any chemical changes. As a result of these physical and chemical properties, thermoplastic materials have low melting points while thermoset products can withstand higher temperature without loss of its structural integrity.
