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: Can plastic tubes be used for vacuum applications?: Yes, plastic tubes can be used for vacuum applications.

Q: Are plastic tubes flexible or rigid?: Plastic tubes can be both flexible and rigid, depending on their material and design.

Q: The babies are 5 days old and we haven't touched them yet. I read that the plastic tubes were bad for the babies ventilation but im afraid if we move them that she will eat them. She built the nest in one of the circles that stands upright. what do i do?: As long as she isn't too stressed out, is getting proper nutrition, and has a roomy cage, she will most likely not harm the babies. I used to breed mice for snake food and messed with the babies all the time. If you move them, the mom will just make a new nest. She might carry them to a different spot where she sees more fit, which is fun to watch, but if you want to remove them from the tube it should be safe :) Good Luck!!

Q: How are plastic tubes filled with products?: Plastic tubes are typically filled with products using various methods such as manual filling, semi-automatic filling machines, or fully automated filling lines. The products are usually pumped or poured into the tubes through the open end, and then sealed using heat or a mechanical process.

Q: What are the advantages of using plastic tubes in the electrical packaging industry?: One advantage of using plastic tubes in the electrical packaging industry is their durability. Plastic tubes are strong and can provide protection to electrical components during transportation and storage. Additionally, plastic tubes are lightweight, which makes them easy to handle and reduces the overall weight of the packaging. Another advantage is that plastic tubes can be easily molded into various shapes and sizes, allowing for customization and efficient use of space. Furthermore, plastic tubes are non-conductive, providing electrical insulation and reducing the risk of damage or short circuits.

Q: Are plastic tubes suitable for automotive applications?: Yes, plastic tubes are suitable for automotive applications. They offer several advantages such as being lightweight, corrosion-resistant, and cost-effective. Plastic tubes can be used for various automotive purposes such as fluid transfer, ventilation, and electrical wiring.

Q: Is it difficult to sell plastic pipes now?: A good sense of propriety will not be too annoying. As long as the other side does not hate you, you have a chance.A lot of problems are easier said than done. If you do, you have the chance, not do it! No chance.

Q: how do you get 2 pieces of plastic tube unstuck?: Try this, make one end cold and the other end hot. The cold pipe will contract and the warm pipe will expand, making it easier to separate.

Q: Something that can coil up.: hardware stores, home depot or lowes, or any marine/boating store.

Q: It needs to be a bit smaller than a pringle tube, min 2mm thickness bout 30cm length maybe 5cm diameter. I need to be able to seal both ends and its got to be sturdy not squashy and preferably shatter proof.Ive seen mailing tubes and poster tubes even baseball bat tubes but there all either too big or come in packs I only need 3...can anyone help? P.s im in the U.K: you smoked something that you didnt even know what the hell it was? are you CRAZY!? it could have been anything, the equipment used doesnt really point to what was used. it could have been Meth amphetamine, Crack, Marijuana, or any manner of chemical/drug. i suggest that next time if your going to use, you atleast find out what it is. Edit_ if it was a tube like a small pipe, it probably wasnt marajuana, it's usually placed in a bong (google it), made into a ciggrette/joint/spliff/blunt or made into a food to consume.
