What makes rubber flexible?

rubber is flexible as its monomer which is isoprene (in case of natural rubber) and isoprene has elastomeric nature and this the resion why rubber is flexible.

What element makes rubber flexible?

What makes rubber so elastic? Like plastic, rubber is a polymer, which is a chain of repeating units called monomers. In rubber, the monomer is a carbon compound called isoprene that has two carbon-carbon double bonds. The latex fluid that seeps from rubber trees has many isoprene molecules.

Is rubber flexible material?

As we know, rubber is flexible. Not just in terms of its elastic and malleable mechanical properties either.

Is rubber elastic or flexible?

Being elastic means being able to be stretched, like a rubber band or a spring while being flexible refers to being able to be bent like a plastic ruler or even a wire. An object that is flexible may not necessarily be elastic as it may be able to bend but it cannot be stretched.

What causes rubber to expand?

The rubber band actually expands when it gets colder! This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract. When the chains cool down, they relax and stretch out, causing the material to expand.

Why does rubber become stiff on stretching?

As the molecules prefer to be coiled to a certain degree, rather than stretched out, the polymer molecules easily get tangled together. When chains become entangled, their mobility decreases. The cross-links inhibit the motion of the polymer chains and so increase the stiffness of the rubber.

What causes rubber to harden?

Most elastomers undergo rubber degradation over time and the most common rubber deterioration causes are exposure to light, oxygen (ozone) and heat. Hardening is more common because free radicals produced due to heat, oxygen and light combine to form new crosslinks, which reduces the flexibility of the rubber.

Why vulcanised rubber is more elastic?

In the process of vulcanization, the added sulfur allows some C-H bonds to be broken and replaced by C-S bonds. Vulcanized rubber is about 10 times stronger than natural rubber and is also about 10 times more rigid. However, it is still very elastic, which means that is can be stretched reversibly.

What rubber is flexible?

Neoprene Rubber. Nitrile Rubber. Synthetic Rubber. Thermoplastic Elastomers (TPE)

What are flexible materials?

Flexible materials can be characterized by the ability to bend or compress easily without cracking under normal conditions. The Gund Company manufactures, converts, and distributes papers, films, and flexible elastomeric materials.

How does elasticity and flexibility differ?

Elasticity means the object will regain its original form as soon as the deforming force is removed. Flexibility means the object is just easily deformed, and will stay that way.

Does rubber expand?
