#1 What are elastomers? - A comprehensive introduction
Elastomers are fascinating materials that are characterized by their extraordinary ability to return to their original shape after being deformed.
This property makes them an indispensable component in many applications, from the automotive industry to medical technology.
The definition of elastomers
Elastomers, often referred to simply as “rubber”, are polymers with the unique ability to expand when stretched or compressed and then return to their original shape.
This property, known as elasticity, distinguishes elastomers from other materials such as plastics or metals.
Types of elastomers
There are two main categories of elastomers: natural and synthetic. Natural elastomers, such as latex, are obtained from the sap of certain plants.
Synthetic elastomers, such as neoprene or silicone, on the other hand, are produced chemically and often offer improved properties for specific applications.
| Type of elastomer | Type of elastomer Description | Typical application |
|---|---|---|
| Natural rubber (latex) | Obtained from plant sap | Tires, tubes |
| Neoprene | Synthetic, oil-resistant | Diving equipment, seals |
| Silicone | Heat-resistant, flexible | Cooking utensils, medical devices |
#2 The science behind elastomers
Elastomers are not only interesting because of their practical applications, but also because of the fascinating science behind their unique properties.
In this section, we will take a closer look at the composition and function of elastomers.
Composition and properties of elastomers
Elastomers consist of long polymer chains that can be deformed under tension or pressure and then return to their original shape.
This flexibility is due to the chemical structure: The polymer chains are cross-linked, which allows them to stretch and contract again.
- Chemical structure: Elastomers consist of polymers with a flexible, cross-linked structure.
- Physical properties: They are known for their high elasticity, resistance to environmental influences and damping properties.
How elastomers work
When an elastomer is stretched, the polymer chains expand. After the force is removed, these chains return to their original position.
This property enables elastomers to be used in a variety of applications where flexibility and resistance are required.
- Behavior under stress: Elastomers can stretch to a certain extent without being damaged.
- Recovery after deformation: After relief, they return to their original shape.
Environmental factors and their effects
The properties of elastomers can be influenced by various environmental factors. Temperature, chemicals and UV radiation can affect elasticity and durability.
- Temperature: Extreme cold or heat can affect elasticity.
- Chemical influences: Some chemicals can attack and weaken elastomers.
- UV radiation: Long-term exposure to UV radiation can lead to embrittlement.
