What is a polyethylene tube?

polyethylene tube is a type of flexible pipe that is commonly used in laboratories, as well as for water transport, including drinking water. Its main ingredient, polyethylene, is a polymer chain made of ethylene molecules that consist of carbon and hydrogen. It can be made in different densities depending on the way it will be used. Polyethylene is the most widespread plastic in the world.

There are two common categories of polyethylene pipes: low density and high density. The polyethylene tube is considered to be a low density if it weighs between 0.0814 oz and 0.0839 oz on a cubic thumb (0.91 and 0.94 grams per cubic centimeter). The low density polyethylene (LDPE) has the advantage of being very flexible and highly resistant to cracks. It is also possible to use a wide range of temperatures. Many types are approved for use with drinking water and other food handling applications.Y greater than 0.084 oz on a cubic thumb (0.941 grams per cubic centimeter). It's not as flexible as LDPE, but stands with sterilization of cooking. This may be an important advantage, especially when used to handle food. Corrosive chemicals also resist the HDPE chemicals better than LDPE, making them preferred for scientific applications.

polyethylene is a compound that does not occur in nature and must therefore be synthesized in a laboratory or industrial environment. For this reason, its wide range was limited to the 20th century and further. The first person to synthesize polyethylene was German chemist Hans von Pechmann in 1898. Several other scientists were able to produce it in laboratory conditions in the next few decades. Only in 1935 was the practical method for the production of polyethylene on a larger scale was invented.

Polyethylene as a compound actually has many more uses than just as part of polyethylene pipes. Is also strongly used inMany consumer products, including dairy cartons, shopping bags, shrink containers and garbage containers, to name at least some. Some types of polyethylene have a very high molecular weight, resulting in a very stiff material. It is strong enough for use in bulletproof vests and cutters. Yet it is also sufficiently chemically inert to create parts of implants used in hip and knee replacements.
