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:Considering it sort of a plumbing project... also, if possible, keep it as cost-effective as possible? Is there a particular fitting I need to use? And I want the tube to connect internally (tube is inside fitting) as opposed to externally.Thanks in advance!: If it's flexible tubing, there are nylon barbed fittings at nearly any hardware store that will fit your specifications. One end will fit inside the tube, secure with a tightened hose clamp after screwing the threaded end into the female fitting. If it's a pressurized application, wrap the threaded end with teflon tape before tightening. You may have to use a series of bushings to step up the threaded end if the sizes are too far off. Most home stores can fix you right up, must make sure you take all your diameters of the fittings and tube with you.

Q:It comes in a plastic bag, no information is on it such as what plastic number it is. Tried google but nothing relevant is coming up.PLEASE LIST RESOURCE.Thank you.: I had a lot of trouble with my lungs for a number of years after I contracted chicken pox (went into my lungs). I ended up with quiet a bit of tubing. I had fishtanks, and that tubing is perfect for conecting different air hoses in fishtanks. Same stuff you purchase at the pets stores, and pay quiet a bit for. If you don't have fishtanks yourself, you can offer it to someone who does. It can be re-used on fish tanks quiet safely for the fish. You can offer it for free on Craigslist or Freecycle to someone with fishtanks, if you don't know someone personally. ~Garnet Permaculture homesteading/farming over 20 years

Q:How are plastic tubes manufactured?: Plastic tubes are typically manufactured through a process called extrusion, where raw plastic material is melted and forced through a die to form a continuous tube shape. This tube is then cooled and cut into desired lengths. Various additives may be incorporated during the extrusion process to enhance the properties of the plastic tube, such as colorants or UV stabilizers.

Q:Can plastic tubes be used for household plumbing?: Yes, plastic tubes can be used for household plumbing.

Q:Can plastic tubes be used for medical purposes?: Yes, plastic tubes can be used for medical purposes. They are often used as catheters, intravenous (IV) tubes, or as respiratory tubes in medical settings. Plastic tubes are flexible, easy to sterilize, and can be customized for various medical procedures, making them a common choice in healthcare.

Q:So I was eating GoGurt yogurt. And I think I accidentally swallowed a part or the jagged part on the top of the tube. I don't think it was very big. I'm guessing the size was the size of half of a dime or a 1/4 of a dime. I know this doesn't sound too bad, since I've heard people who swallowed pennies, then they were fine, but I don't know how to get rid of it. I can still breathe and drink normally, but when I talk for too long, my throat starts to hurt a little. So far, I've tried drinking lots of water, swallowing some food to push it down (rice. :D), coughing, vomiting, and clearing my throat but I think it's still there. I'm actually not sure if it's still there or if it is gone, or just made a cut so it hurts. But I don't want to go to the doctors or ER, I'm poor. Are there any other ways to get the plastic out? Oh and if I leave it there, how long will it take for it to go down my throat and digest?: I doubt there's anything solid still in your throat. The pharynx in lined with mucus membrane and it's a sensitive tissue as well. It's made to allow things to slide through but it's also sensitive as a protective measure. I expect some very small area in your oropharynx or laryngopharynx was mildly irritated. It will resolve spontaneously. Did you for some reason think this might be the first time this has happened in the history of man? (I'm just teasing you) Don't force the coughing, vomiting (this raises new issues) or throat-clearing anymore, that serves only to further and prolong the irritation. Ignore it and by tomorrow afternoon, you'll suddenly realize your throat no longer hurts. @ Daniel, neither of what you list is CPR. I think you're trying to describe abdominal thrusts and a mouth sweep. These measures can be utilized along with CPR when they are appropriate. You've demonstrated clearly that not only do you do not know to perform either one but that you do not understand the purpose of them.

Q:it has one hose connected to one end and two hoses on the other end. think it might have something to do with heater core or something.: the single end is attached to the lower radiator hose the double end one hose goes to the lower part of the intake and the other goes to the heater core this is just a transfer tube across the front of the vehicle

Q:I recently bought my house in the dead of winter while there was snow on the ground. The snow has recently melted and revealed that there is about a 6-8 inch plastic tube sticking out of a hole in my lawn. Anyone have any idea of what it is? It is flush with the grass and close to the sidewalk.: sounds like a drain pipe for water if and when you get heavy rain...

Q:Can plastic tubes be used for transporting powders?: Yes, plastic tubes can be used for transporting powders. They are commonly used in various industries such as pharmaceutical, food, and chemical industries to transport powdered substances efficiently and safely. Plastic tubes offer advantages like being lightweight, durable, and resistant to corrosion, making them suitable for transporting powders of different types and sizes.

Q:Are plastic tubes suitable for medical diagnostics?: Yes, plastic tubes are suitable for medical diagnostics. They are commonly used in various diagnostic procedures, such as blood collection, urine testing, and sample storage. Plastic tubes are lightweight, cost-effective, and have excellent chemical resistance, making them suitable for handling and transporting biological samples in a safe and efficient manner. Additionally, they are available in different sizes and configurations to accommodate specific diagnostic needs.
