WebThe intermolecular forces may be hydrogen bonds or dipole-dipole interaction. Fibres have sharp and high melting points. A common example is that of Nylon-66, which is used in carpets and apparels. The above was the general ways to classify polymers. Another category of polymers is that of Biopolymers. WebApr 10, 2024 · Plastic is any synthetic or semisynthetic organic polymer. In other words, while other elements might be present, plastics always include carbon and hydrogen. While plastics may be made from just about any organic polymer, most industrial plastic is made from petrochemicals. Thermoplastics and thermosetting polymers are the two types of …

WebIn Simple words, it is a plastic that solidifies and takes on a permanent "set" in shape as a result of a chemical reaction that occurs when it is heated. As a result, unlike thermoplastics, thermosetting plastic cannot be melted down and reshaped after being moulded into a certain shape. Instead, it keeps its shape and characteristics forever.

As a result, unlike … WebUnlike thermoplastic resins, once they have set, thermosetting resins maintain their excellent physical properties and cannot be reworked. They can have different colours and different surface finishes. They offer good performance in terms of resistance to weight. They conduct heat. They are corrosion- and water-resistant.
