Elastomer

Elastomer

Elastomer (/ɪˈlæstəmər/), derived from the Greek words 'elasin' meaning 'to drive' and 'meros' meaning 'part', is a type of polymer that exhibits elastic or rubbery properties.

Etymology

The term 'elastomer' is a combination of the words 'elastic' and 'polymer'. It was first used in the early 20th century to describe materials that behave like natural rubber. The word 'elastic' comes from the Greek 'elasin', meaning 'to drive', and 'polymer' is derived from the Greek 'poly', meaning 'many', and 'meros', meaning 'part'.

Properties

Elastomers are characterized by their high elasticity, which allows them to return to their original shape after being stretched or deformed. This is due to the flexible, long-chain molecular structure of the polymers, which can be stretched and then return to their original shape when the stress is removed.

Elastomers are also known for their resilience, durability, and resistance to abrasion and impact. They are often used in applications where a high degree of flexibility and toughness is required.

Types of Elastomers

There are many different types of elastomers, each with its own unique properties and uses. Some of the most common types include:

• Natural rubber: Derived from the sap of the rubber tree, this is the original elastomer. It is known for its excellent elasticity and resilience.

• Synthetic rubber: These are man-made elastomers designed to mimic the properties of natural rubber, but with improved resistance to heat, chemicals, and weathering.

• Silicone: A type of synthetic rubber known for its excellent heat resistance and flexibility over a wide temperature range.

• Thermoplastic elastomers (TPEs): These are a type of plastic that behaves like rubber at room temperature but can be molded and shaped when heated.

Applications

Elastomers are used in a wide range of applications due to their versatile properties. They are commonly used in the manufacturing of tires, belts, hoses, gaskets, and seals. They are also used in the medical field for items such as catheters, gloves, and implants.
