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: Are plastic tubes suitable for freezing temperatures?: Plastic tubes are generally not suitable for freezing temperatures as they tend to become brittle and can crack or break under low temperatures.

Q: What is the maximum length of plastic tubes?: The maximum length of plastic tubes can vary depending on the specific type and manufacturing capabilities, but it can range from a few feet to several hundred feet.

Q: I have a bear hamster she hates cardboard tubes she already has a wheel and a ball and a play pen even a little house dont sugest plastic tubes because i have her in a little fish tank like cage tubes wont work thx: Years ago I owned a hamster and she had a treadmill and never got bored with it.If I didn't have so many cats I wouldn't mind owning another hamster.

Q: How to remove the odor of plastic pipe?: Remove the odor of plastic pipe, it is best to use hot water more than a few times, more bubbles a few times, add some fragrance agents, I tried with hot water, the effect can also be... Mainly is to use hot water bubble

Q: A piece of plastic tubing is 19 inches long and must be divided into 6 smaller pieces each at least 2 inches long. What is the largest length of tubing possible?: you have 19 inches total. assuming that five of them can be 2 inches long 5 * 2 = 10 so subtract that from total length you can have one piece 19 - 10 = 9inches

Q: Can plastic tubes be used for geothermal heating systems?: Yes, plastic tubes can be used for geothermal heating systems. Plastic pipes, such as high-density polyethylene (HDPE) or cross-linked polyethylene (PEX), are commonly used in geothermal installations due to their excellent resistance to corrosion, flexibility, and durability. These tubes can effectively transport the geothermal fluid (water or antifreeze solution) between the heat pump and the underground geothermal loops, ensuring efficient heat transfer and system performance.

Q: Are plastic tubes suitable for use in the packaging industry?: Yes, plastic tubes are suitable for use in the packaging industry. They are lightweight, versatile, and offer various sizes and shapes to suit different products. Plastic tubes provide excellent protection, are cost-effective, and can be easily customized with labels and closures. Additionally, they are resistant to moisture, chemicals, and impact, making them ideal for packaging a wide range of products such as cosmetics, pharmaceuticals, and food items.

Q: Can plastic tubes be used for pneumatic conveying?: Yes, plastic tubes can be used for pneumatic conveying. Plastic tubes are commonly used in pneumatic conveying systems due to their lightweight, corrosion-resistant, and cost-effective properties. They are suitable for transporting various materials such as powders, granules, and pellets, making them a versatile choice for pneumatic conveying applications.

Q: Can plastic tubes be used for solar panel installations?: Yes, plastic tubes can be used for solar panel installations. They are commonly used as conduits to protect and route electrical wires from the solar panels to the electrical system. Plastic tubes are lightweight, durable, and resistant to weather elements, making them a suitable choice for outdoor solar panel installations.
