Rubber

タイトルまたは説明

Rubber is an elastic material that can be produced naturally from various plant sources or synthetically through a variety of chemical processes. It has been in use for thousands of years, during which time it has been produced in numerous variations with distinct characteristics that make them suitable for different applications.

It serves as an essential raw material in the production of everything from automobile tires to surgical gloves. However, successfully producing these components necessitates choosing the right type of rubber for the given part design and application environment. For this reason, weve provided an overview of some of the most commonly available rubber types, outlining what they are, their key properties, and their typical uses. 

Basic Properties of Rubber

As indicated above, rubber comes in several variations, each of which has unique properties. However, most—if not all—rubbers also share a few common characteristics, such as:

• Elasticity: The molecular structure of rubber materials allows them to return to their normal shape after being compressed or stretched. This characteristic is apparent in rubber bands. Stretching or compressing a rubber band temporarily pulls or pushes the individual molecules out of alignment with each other. As the molecules are attached to one another, they return to their original position once the stretching or compressing force is removed.
• Thermal contraction: While most materials expand when heated, rubber contracts. This unusual phenomenon results from how the rubber molecules respond to heat. When heat is applied, the already-tangled molecules become more tangled and twisted. When heat is removed, the molecules return to their resting state and the rubber regains its original shape.
• Durability: Most rubbers are highly durable, resisting damage and degradation from abrasive and tearing forces, impact, low temperatures, and water. They also exhibit a relatively slow heat buildup rate.
