Physical properties[edit]

Polyethylene is a thermoplasticpolymer consisting of long hydrocarbon chains. Depending on the crystallinity and molecular weight, a melting point and glass transition may or may not be observable. The temperature at which these occur varies strongly with the type of polyethylene. For common commercial grades of medium- and high-density polyethylene the melting point is typically in the range 120 to 180 °C (248 to 356 °F). The melting point for average, commercial, low-density polyethylene is typically 105 to 115 °C (221 to 239 °F).it is transprant.

Chemical properties[edit]

Most LDPE, MDPE and HDPE grades have excellent chemical resistance, meaning that it is not attacked by strong acids or strong bases. It is also resistant to gentle oxidants and reducing agents. Polyethylene burns slowly with a blue flame having a yellow tip and gives off an odour of paraffin. The material continues burning on removal of the flame source and produces a drip.^[3] Crystalline samples do not dissolve at room temperature. Polyethylene (other than cross-linked polyethylene) usually can be dissolved at elevated temperatures in aromatic hydrocarbons such as toluene or xylene, or in chlorinated solvents such as trichloroethane or trichlorobenzene.^[4]

Q:Can plastic tubes be used for pool equipment?: Yes, plastic tubes can be used for pool equipment. They are commonly used for applications such as pool filters, pumps, and plumbing systems due to their durability, resistance to corrosion, and ability to withstand water pressure.

Q:Can plastic tubes be used for household products?: Yes, plastic tubes can be used for a variety of household products such as toothpaste, lotions, creams, and even food items like sauces and condiments.

Q:What is the maximum temperature plastic tubes can withstand without deformation?: The maximum temperature that plastic tubes can withstand without deformation depends on the specific type of plastic being used. However, many common plastics have a maximum temperature range of around 150-200 degrees Celsius before they start to deform.

Q:What are the different sizes available for plastic tubes?: There are various sizes available for plastic tubes, ranging from small diameters like 1/8 inch to larger diameters like 4 inches or more. The specific sizes depend on the manufacturer and the intended use of the tube.

Q:What is the minimum wall thickness for plastic tubes?: The minimum wall thickness for plastic tubes can vary depending on the material and manufacturing process used. However, in general, it is recommended to have a minimum wall thickness of around 0.5 millimeters to ensure structural integrity and prevent potential issues like leakage or collapsing.

Q:I already have a plastic water line with a on off switch coming up through the floor. I bought a new fridge and when they delivered it they said they could not install it because of the plastic tube- they said I had to change it- I've been to home depot etc and have no clue how to do it because everything else seems to be for the actual installation of a brand new line whereas in this case I need to know how to change the existing line. Any answers??: You shouldn't have to change the tubing all refers as far as I know come with a 1/4 in line. Get a adapter from Home Depot or Lowe's and you should be good to go. You might cut off a small piece of you old tubing and the fitting on the refer and take them with you that should help a lot. Good Luck

Q:Can plastic tubes be used for pneumatic applications?: Yes, plastic tubes can be used for pneumatic applications. Plastic tubes are often used in pneumatic systems due to their lightweight, flexible, and durable properties. They can effectively transmit compressed air or gases and are resistant to corrosion. However, it is important to consider the specific requirements of the application and select a plastic tube material that is suitable for the desired pressure, temperature, and chemical resistance.

Q:Do plastic tubes have any limitations in terms of gas permeability?: Yes, plastic tubes do have limitations in terms of gas permeability. While some plastics have low gas permeability, others may allow certain gases to pass through. The permeability depends on the type and quality of plastic used. Therefore, it is important to consider the specific application and requirements when selecting plastic tubes for gas containment.

Q:Can plastic tubes be used for agriculture applications?: Yes, plastic tubes can be used for agriculture applications. They are commonly used for irrigation systems, drainage, and as protective covers for plants. Plastic tubes are durable, lightweight, and can be easily installed, making them a practical choice for various agricultural needs.

Q:Owner of Toyota Corolla 95 4AFE: What do you call the (rubber/plastic) tube connecting the air filter to the engine?: Intake.
