Elastomers are very elastic polymers. The cross-linking of the monomers in them is very light and is arranged in an irregular pattern. Thus, the intermolecular forces between the chains of polymers are quite weak. Elastomers are expected to be one large molecule having macroscopic size.
The chains present in the structure are very flexible and when a small force is applied to them, it results in deforming the structure. There are three classes of elastomers i.e. diene, non-diene, and thermoplastic elastomers. Injection molding, transfer molding, and compression molding are three ways through which the manufacturing of elastomeric parts is achieved.
