Rubber bands are a stretch of rubber and latex in the shape of a loop and are
widely used to hold objects together. Rubber bands are known by various
names like binder, elastic, elastic bands, lacker band or gumband. These
bands are frequently used in many businesses, industries as well as at home.
They are well suited for holding multiple objects together and are reusable
and economical. Rubber band sizes vary according to their intended use.
These elastic rubber band colors too differ. Today, in the 21st century, rubber bands are
considered one of the most convenient rubber products, used by many
individuals and industries for a wide variety of purposes. Industrial rubber
bands are made to perform heavy duty. These industrial rubber bands have
specific sizes and are very strong rubber bands , designed to stabilize
almost any size load.
Manufacturing Process of Rubber Band
Rubber bands manufacturers make them by extruding rubber into a long tube to give its general shape, placing
these tubes on mandrels and curing the rubber with heat, slicing it across
the width of the tube into small rubber bands. For making the long rubber
tube, the rubber band manufacturers use high grade
, which is then sliced
into little bands. Rubber bands are also manufactured using
because of its superior
elasticity. With the vulcanization process and emergence of synthetic
rubber, these bands have become more durable and elastic. The size of a
small rubber band can be less than an inch in diameter, while large rubber
bands can be several feet across. For detailed manufacturing process of

Rubber Bands: The
Rubber Bands Sizes and Measuring
Standard rubber bands are
assigned a "size number" that corresponds to the dimensions of the
elastic rubber band - its length, width and thickness dimensions. Following
are the details of the measuring of rubber band sizes-
- Length: The length of a band is half its circumference.
- Thickness: The thickness of rubber band is the distance from
its inner circle to the outer circle.
- Width: The height of that band or cylinder is its width.
Rubber Bands Sizes
various number of standard rubber band sizes available in the market. If the
appropriate size is not available with the rubber bands wholesale suppliers,
they can get custom rubber bands made through the rubber band manufacturers
according to customers' exact specifications. Customers can specify the
diameter, width, and wall thickness of the rubber band size that they
require. They can also get printed custom rubber bands.
Rubber Bands Size Numbers
Rubber Bands Size Numbers
bands are given a standard number based on dimensions. Usually the are numbered starting from smallest to largest, width first.
Therefore, rubber bands numbered 8-19 are 1/16 inch wide, with length
ranging from 7/8 inch to 3 1/2 inches. The numbers 30-34 are 1/8
inch wide, going again from shorter to longer. Even for long rubber bands,
the numbering starts over for numbers above 100, again starting at width
Types of Rubber Used in Rubber Bands
All rubber bands are not made
of the same material. There are four primary materials used to make them. They are Natural Rubber, Ethylene Propylene
Diene Monomer (EPM, EPDM), Synthetic polyisoprene, and Silicone compounds.
These materials have special properties that make them best for certain
Rubber Bands Uses
The rubber bands are used to hold a large number
of things such as follows:
- They are used to suspend hard drives in a computer case.
Suspending hard drives help in avoiding contact between the hard drives
and the computer case. This in turn results in reducing vibrations to
the case, thereby reducing noise in the computer case.
- They are often used in orthodontics. This helps to realign
teeth over a period of time.
- They can also serve the purpose of an eraser by simply wrapping
a rubber band tightly around the end of a pencil.
- They are used during aerobic exercising as fitness tools. In fact, the wrist rubber bands are an important sports accessories too.
- They are sometimes used to power model aircraft or other
mechanical toys because of its property of stretchable. When the rubber
band untwists itself, it will help to rotate the wings affixed to it.
- They are used as projectiles.
- They are used to hold small objects or file papers or in many
official uses etc.
Applications of Rubber Bands
Rubber Bands have an extensive range
of applications in both heavy and small industries like
agriculture,packaging, stationery, fishery, transportation, leisure trades
etc. the heavy duty industrial rubber bands are used for more demanding jobs.
Rubber Bands Consumption in US
Rubber bands have a large variety
of uses and have become one of the United States business staple over the
years. The largest consumer of rubber bands in the world is the U.S. Post
Office. There is annual order of millions of pounds of bands which
are used in sorting and delivering piles of mail. The newspaper industry
also uses their large quantities to keep individual newspapers
rolled or folded before they are delivered from home to home. Another large
consumer of rubber band is the agricultural products industry. The flower
industry uses them to hold together bouquets. They are also
tied around the petals of flowers (especially tulips) to keep them from
opening in transit. Vegetables such as celery are bunched together with
the help of these bands. The plastic coverings over broccoli, cauliflower, other
vegetables and fruits are often tied with them. All in all, more
than 30 million pounds of rubber bands are sold in the United States alone
