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: How do plastic tubes compare to ceramic tubes in terms of weight?: Plastic tubes are generally lighter in weight compared to ceramic tubes.

Q: Can plastic tubes be used for paint or adhesive packaging?: Yes, plastic tubes can be used for paint or adhesive packaging.

Q: Can plastic tubes be used for irrigation purposes?: Yes, plastic tubes can be used for irrigation purposes. They are often used as an affordable and durable option for transporting water to crops and plants in agricultural settings. Plastic tubes are lightweight, resistant to corrosion, and can be easily installed, making them a popular choice for irrigation systems.

Q: The water dispenser tube on the outside front has a hard yellow substance on the end of the tube. I don't know what it is or how to get the tube out to clean it.: Sounds like sulphur. You must have sulphur in your water. Scrap it off and expect to have to do it again. Good luck I believe the GE models the tube is foamed in place not changable by itself. The entire door would have to be changed out. very expenssive. Try a small bottle type brush to clear it. Good luck

Q: I want to bleed my clutch but I was wondering if I can do it without the plastic tube that goes on the bleed nipel??? Help?: Yes, but it is a bit messy. Same procedure - person A opens the nipple about 1/2 turn, person B presses the clutch pedal down, A closes the nipple finger tight, B pulls the pedal up with his foot, repeat.... Use rags, paper towels, shop towels, or whatever to soak up the brake fluid as it comes out. An important note is that brake fluid is subject to spontaneous combustion when soaked up. (Brake fluid is a notorious part of the arsonist's toolbox.) Wet the soaked rags with water and seal them in a zip-lock bag or something else to keep air out before disposing of them.

Q: How much should it cost to replace the Mass Airflow tube on a 2000 Mazda Protege? The tube is ripped, so it's messing with the MAF sensor. The mechanic quoted me $50 for the part (not including labor), and I just want to make sure they're not over-charging me. I mean, it is just a plastic tube...: www.okorder / Click this:

Q: How do you cut plastic tubes to size?: To cut plastic tubes to size, you can use a few different methods depending on the thickness of the tube and the tools available.
