Neoprene vs. Elastomer — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Updated on May 2, 2024
Neoprene, a synthetic rubber known for its stability and heat resistance, contrasts with elastomers, which refer broadly to elastic polymers used in various applications.

Key Differences
Neoprene is a specific type of synthetic rubber developed as an oil-resistant substitute for natural rubber, while elastomers encompass a wide range of polymers, both natural and synthetic, characterized by their elasticity.
Due to its chemical structure, neoprene exhibits excellent chemical stability and remains durable under a wide range of temperatures, whereas elastomers in general may vary significantly in their thermal and chemical stability based on their composition.
Neoprene is particularly noted for its resistance to oils, solvents, and weathering, making it ideal for industrial and automotive applications. On the other hand, the resistance properties of elastomers can vary; for instance, silicone elastomers are highly resistant to heat but less resistant to petroleum-based oils.
In applications requiring specific performance attributes such as flame retardancy and low smoke emissions, neoprene stands out, whereas other elastomers might need additional treatment or blending with other materials to achieve similar properties.
The production of neoprene involves the polymerization of chloroprene, making it more specialized, whereas the production methods for elastomers can range from simple extrusion to complex molding processes depending on the type.

Neoprene was quickly adopted in many industrial applications.
Elastomer
Used widely in the manufacturing of flexible products.
Elastic bands are typically made from elastomers.
Neoprene
Commonly used in wetsuits due to its thermal insulation properties.
Surfers prefer neoprene wetsuits for cold water.
Elastomer
Includes both natural and synthetic varieties.

Neoprene
Neoprene (also polychloroprene) is a family of synthetic rubbers that are produced by polymerization of chloroprene. Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range.
Elastomer
An elastomer is a polymer with viscoelasticity (i.e., both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus and high failure strain compared with other materials. The term, a portmanteau of elastic polymer, is often used interchangeably with rubber, although the latter is preferred when referring to vulcanisates.
Neoprene
