define the folliwing term polythene and artificial silk ,thermoplastics ,thermosetting plastic
Answers
Answer:
Polythene=a tough, light flexible synthetic resin made by polymerizing ethylene, chiefly used for plastic bags, food containers, and other packaging.
Artificial silk=Artificial silk or art silk is any synthetic fiber which resembles silk, but typically costs less to produce. Frequently, "artificial silk" is just a synonym for rayon. When made out of bamboo viscose it is also sometimes called bamboo silk.
Thermoplastics=A thermoplastic is a material, usually a plastic polymer, which becomes soft when heated and hard when cooled. Thermoplastic materials can be cooled and heated several times without any change in their chemistry or mechanical properties. Whenthermoplastics are heated, they melt to a liquid.
Thermosetting plastic=A thermosetting plastic is a polymer that irreversibly becomes rigid when heated. Such a material is also known as a thermoset orthermosetting polymer. ... Heat provides energy for chemical reactions that increase the cross-linking between polymer chains, curing the plastic
