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:Long story short.....I would like to create my own pen from scratch. Where can I find the empty plastic tubes for the ink?: Pen Tubes

Q:theres a list on one end of the tube with the objects in the tube, you have to shake the tube and look for the different objects. what is this game called? i'l like to buy it for a friend: I don't actually know of a place that sells them. I have had one made for me here is wat they did.... What you need... An Empty water/soda bottle (remove the wrapper logo thing) Some Sand 10 or more little objects that will fit in the bottle to be found A piece of string and a list of the items you put in the bottle. Ok take the bottle and put some sand and a few items shake it up and keep doing that until it is full... make sure you write down all the items you put in... the super glue the cap on... the punch a hole in the list and put the string through it and tie it around the neck of the bottle. There you go you got one that means even more because you made it.

Q:Can plastic tubes be used for sewer lines?: Yes, plastic tubes can be used for sewer lines. Plastic pipes such as PVC (polyvinyl chloride) and HDPE (high-density polyethylene) are commonly used in modern sewer systems due to their durability, corrosion resistance, and ease of installation.

Q:I have a Katadyn Vario pump for camping and haven't used it in eons (7 years or so) and I took it apart to clean it.For now, and for future reference, how can I clean the actual intake/outlet plastic tubes? The inlet tube is inserted into gross pond/lake or running stream water, so it's already contaminated. I would love to be able to wash this tube for SURE, safely at home.(The O-rings are still well-lubed, and I've ordered new activated carbon to refill the glass fiber filter.): Sure, just use dishwashing liquid (not the type that goes in the dishwasher - too caustic). And you can also rinse it with a weak bleach solution (a teaspoon in a gallon of water) to disinfect it, then flush it well with fresh tap water. I did exactly those steps with my neglected filter before taking it on vacation last summer and it worked fine.

Q:OK I am trying to make one of those soda drinking hats (because I have all of this spare clear plastic tubing from Menards from another project, and I couldn't think of anything else to do with it). When drinking out of it, it gives that plastic-like taste which I hope will go away over time. Anyway is this bad for me because I don't know if there is a different cleaner tubing that the real hats use and if it is safe to drink from their tubes. Should I just buy one of the hats off OKorder or just make my own... I don't want to poison myself or anything.: what kind of tubing was it? was it sitting in the garage for months? the plastic taste isnt bad, but if it was sitting in your garage for months, you might wanna run soappy water throught it a few times then run clean water throught it for a few mins....just to be safe

Q:im just wondering: I guess you are asking about the small plastic tubes inserted in the ear to drain them. My husband had to have one several years ago because there was so much fluid in the Eustachian tube. When you go swimming or shower, you have to put cotton in the ear and cover it with Vaseline so no water will get in. It gets messy. Many times these tubes will fall out on their own. Otherwise, they're left in for a couple of months at a time. They are very tiny tubes.

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:Hehehe I love freeze pops. My favorite flavor is lime. :): The red ones, I don't even care if they're strawberry or cherry, never really noticed! I just like em the most!

Q:This will be more efficient since right now the bed covers the vent, just wanted to somehow route the cool air away from under the bed so my roommate won't have to turn the air really cold to cool down at night. Thanks in advance.: Move the bed. It's usually easier to do that than deal with a blocked diffuser. Or, since a small window A/C is so cheap nowadays, block the vent and put a window unit in that room.........

Q:I recently purchased a 1972 Volkswagen Super Beetle and I found that the plastic tube above the fuel tank is cracked. I know that it is some sort of vapor trapping device, but i cannot find a replacement: Plastic? check with dealer parts department. More than likely it is a rubber hose that goes back to the air cleaner in the engine compartment.
