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: I've usually see em in the movies and stuff like that. Little long tubes like hand held flares which upon breaking or twisting emits faint green light sort of like the radium stickers and stuff like that and are these available in military surplus stores?: Here in NZ I think they're called cyanolume sticks. They're widely available in shops and they're useful in civil emergency kits, along with candles and a torch. They're useful as a replacement for a torch where there's flammable vapour and you don't want sparks. They get their name from the colour of the light they emit; cyan, or blue-green.

Q: My child left her pierced earrings on way too long. The plastic backs are hardened onto the post. They are not the flat round ones. These are small clear plastic tubes. There must be a softener of some kind, no? Please help.: omg i had this exact same thing happen to me a few weeks ago it took my boyfriend and i forever to get them off... i really dont know the best way to get them off but the way i did it was i sat there and wiggled them back and forth until they finally wiggled down far enough to get pulled off. i know this will be hard to do with a child so i hope someone on here has a better solution to this.

Q: Can plastic tubes be used in high-pressure applications?: Yes, plastic tubes can be used in high-pressure applications. However, the suitability of plastic tubes for high-pressure applications depends on the specific type of plastic and its pressure rating. Some plastic materials, such as reinforced nylon or high-density polyethylene (HDPE), are designed to withstand high pressure and can be used effectively in such applications. It is essential to consult the manufacturer's specifications and guidelines to ensure that the plastic tube chosen is suitable for the desired pressure range.

Q: I'm looking to make my own gas mask bong like the one pictured here . I've looked as jumbo sized plastic test tubes but they are not big enough. I just need a link to buy tubes that big. preferably plastic.: I'd say your best bet is a head-shop or smoke-shop as they sell all sorts of accessories for smoking, the tubes could be homemade or makeshift made in a shop by a tradesmen. Lastly smoking out of plastic is not as good as glass it has more carcinogens or something i remember reading about it somewhere. Hope that helps

Q: What are the advantages and disadvantages of PPR plastic pipes compared with steel pipes?: Copper plastic and stainless steel composite pipes, etc. and plastic pipes (including PE, PPR, PVC, etc.) are compared. Strength comparison, the most commonly used stainless steel water industry, plastic pipe expansion coefficient is too large, is its Achilles heel, not suitable for hot water pipes. In the condition of environmental temperature change, plastic pipe leaks easily and so on

Q: Can plastic tubes be threaded or connected?: Yes, plastic tubes can be threaded or connected using various methods such as push-fit connectors, compression fittings, or by using specialized threading tools and techniques for certain types of plastic tubes.

Q: Is the PPR plastic pipe really poisonous? Is the news true?: The main component of the PPR tube is polypropylene, is non-toxic, but individual manufacturers due to the pursuit of high profits, the production of inferior water, most people will lead to misunderstanding, to distinguish between true and false, false tube has a pungent odor, if not smell, you can intercept a short combustion to see whether there is a pungent odor, if any, that is inferior tube, is harmful to the human body. In addition, if you don't worry about using the PPR tube, you can replace the PPR tube with copper core, but the price is a little more expensive.

Q: would it be toxic?could u melt the tubing to the cups with a lighter?: air line tubing is probobly to thin to make an effective vacuum hose, but no it wouldnt hurt them to try, you could fuse it with a lighter, sound like a lot of work though. what are the cotton balls for? mollies can eat, algea wafer, shrimp pellets, pellet food, granules, flake food, live frozen or freeze dreid= daphnia, shrimp, worms, fruitflies... sliced raw or blanched veggies like cucmber squash, zucini, spinich

Q: Plastic pipe joint leakage of water can be done with glue: Not recommended, you are the water inlet pipe, the water inlet pipe is confined to, even if you use the glue water well, did not leak, soon will leak, you do not know what is the tube, a live connection in Water Leakage place

Q: How do plastic tubes compare to fluoropolymer tubes in terms of chemical resistance?: Fluoropolymer tubes generally exhibit superior chemical resistance compared to plastic tubes. This is due to the unique properties of fluoropolymers, such as PTFE (polytetrafluoroethylene) or FEP (fluorinated ethylene propylene), which have excellent resistance to a wide range of chemicals, solvents, and corrosive substances. Plastic tubes, on the other hand, may vary in their chemical resistance depending on the type of plastic used. While some plastics may offer decent resistance to certain chemicals, they are generally less resistant than fluoropolymers and may be prone to degradation or reaction with certain chemical substances.
