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 use in the aerospace industry?: Plastic tubes are generally not suitable for use in the aerospace industry due to their limited strength and resistance to extreme temperatures and pressures. Aerospace applications require materials that can withstand high stress, extreme environments, and have excellent mechanical properties. Therefore, more durable and high-performance materials like metals and composites are preferred for ensuring safety and reliability in aerospace components and systems.

Q:My 2000 ford focus broke down last week and me and a family friend determined its the fuel pump so as we were replacing it we noticed the nozzle hooking into the top of the fuel pump was snapped it is connected to a hard plastic tube and I need to know either what the tube is called or what the nozzle is called PLEASE HELP!!!: you should have 2 lines to the pump. a supply to the fuel system and a return back to the tank. the red clip is the supply fitting, id believe.

Q:i saw that history of middle ear surgery is a disqualifying factor. will they check records from when i was a toddler?: Do you still have tubes in your ears? If they have been removed, you would be OK. If they are still in. They will know as soon as you are asked to Valsalva.

Q:Can plastic tubes be printed on?: Yes, plastic tubes can be printed on.

Q:the tubes are bout 1cm ID with only about a 1mm thickness. I don't think threading them will be possible, and the seal between that has to be water tight.: you need coupling or socket to connect the two pieces and then apply adhesive to connect, there is a traditional way which you heat up on side to form a spigot or cone shape little wider than 1cm and insert one end while it is hot then press for tightness, this is not good from quality point of view.

Q:Can plastic tubes be used for holding powders?: Yes, plastic tubes can be used for holding powders.

Q:Is rigid PVC double wall corrugated plastic pipe with HDEP pipe one kind?: The materials used are different, the process and formula, and the processing temperature are different. The PVC formula has hundreds of thousands. Hope to adopt, thank you

Q:Okay this is a really horrifying scenario and I'm panicking. I have two 6 weeks old baby alexandarine parrots. I feed them by hand through a syringe. I attach a small rubber tube at the end of the syringe and feed them slowly. However as I was just feeding one, the tube got loose and is now stuck in the parrot's throat. I'm very worried. I can't go to a vet as there is no avian vet in our area. What should I do? Please Please help!! I'll be really thankful.: Go to a regular vet. Though they are not bird-specific, it is still a better chance than trying to remove it yourself and risk damaging their esophagus. Hopefully it's not too late. Please at least call a vet; if you can't go to them, it's possible they can at least tell you how to safely remove the tube.

Q:Are plastic tubes suitable for use in the automotive industry?: Yes, plastic tubes are suitable for use in the automotive industry. Plastic tubes offer several advantages such as being lightweight, resistant to corrosion, and easy to install. They are widely used in various automotive applications, including fuel and brake lines, coolant systems, and air intake systems. Additionally, plastic tubes can be manufactured to meet specific performance requirements and are often more cost-effective compared to other materials.

Q:Are plastic tubes suitable for freezing temperatures?: Yes, plastic tubes are generally suitable for freezing temperatures.
