Question

Bakelite is an example of which plastic?

Answer 1

Hint: We have to know that the plastic can be widely categorized into two types: thermoplastic and thermosetting plastic. Plastics have a high stiffness and a lack of reverse elasticity. Condensation polymers are any kind of polymers formed through a condensation reaction.

Complete answer:
We need to know that the definition of a plastic material is a compound of polymer plus additives that has the capabilities of being shaped or molded into a valuable product. This is done in conditions of moderate temperature and pressure.  Thermoplastic products have the ability to be continually softened, melted and reshaped/recycled, for instance in injection molding or extrusion resins. However, thermoset products do not have this property. In terms of tonnage, thermoplastics are undoubtedly the most significant. If the polymer in the plastic is based on one monomer, it uses the term ‘homo polymer.’ If the polymer used is based on two or more monomers, it is referred to as a ‘copolymer.’ Thermosetting plastics are made up from long chains of molecules that are cross-linked. They have a very rigid structure. Once heated, thermosetting plastics can be molded, shaped and pressed into shapes. Once set they cannot be reheated since they are permanently set.

Bakelite is a thermosetting plastic as it can be molded, reshaped and pressed into different shapes.

Note:
 We have to know that the bakelite is a condensation polymer. A thermosetting plastic is a polymer that irreversibly becomes rigid when heated. Such a material is also known as a thermoset or thermosetting polymer. In condensation polymer molecules join together—losing small molecules as byproducts such as water or methanol.
