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 don't mind cutting the wire but I want to make sure hampster won't get hurt the bubble tube can't be pushed off by her.
- You can fold the wire back so that there are no sharp edges when you cut. You can certainly use zip ties, just check them to make sure your hamster doesnt chew them off. Be creative. Modified cages are fun to make!
- Q: Can plastic tubes be used for veterinary products?
- Yes, plastic tubes can be used for veterinary products. They are commonly used for packaging and dispensing various veterinary products such as ointments, creams, gels, and oral medications. Plastic tubes offer convenience, hygiene, and ease of use, making them a suitable choice for veterinary applications.
- Q: How do plastic tubes perform in extreme weather conditions?
- Plastic tubes generally perform well in extreme weather conditions due to their durability, resistance to corrosion, and ability to withstand temperature variations. However, the specific performance may vary depending on the type of plastic used and the severity of the weather conditions.
- Q: I can never remeber this things name please help! It is a little plastic piece for the tubing.... gt;.lt;
- no return valve is what you're looking for.
- Q: What are the advantages of using plastic tubes in the electrical packaging industry?
- There are several advantages of using plastic tubes in the electrical packaging industry. Firstly, plastic tubes are lightweight, making them easy to transport and handle. Secondly, they provide excellent insulation properties, protecting electrical components from damage and ensuring safety. Additionally, plastic tubes are durable and resistant to corrosion and moisture, making them suitable for various environments. They are also cost-effective compared to other materials, allowing for lower production costs. Lastly, plastic tubes can be easily customized in terms of size, shape, and color, providing flexibility in design and meeting specific packaging requirements.

- Yes, plastic tubes are generally resistant to oil and grease permeation.
- Q: What is the average cost of plastic tubes?
- The average cost of plastic tubes can vary depending on factors such as size, quantity, and quality. However, a rough estimate would be anywhere between $0.50 to $5 per tube.
- Q: Anyone know where I can buy a custom tube (wood, aluminum, or plastic) with the following dimension...??I.D. : 4.0625 inchesO.D.: 4.1875 inchesLength: 1 inch (can be longer, of course)Ive been looking all over the net for custom plastic manufacturers but no success as of yet.Thanks!
- Do you really need spec.s to ten thousanths of an inch and not care about the nature of the material?
- Q: I have a number of plastic tubes of differing sizes that I need to sand the full length of the inside of. The smallest one is less than a centimeter in diameter. I have some long paintbrush handles that fit very well inside, so I've tried to wrap sandpaper around them and insert them into the tubes, but I don't know of a way to sufficiently attach the sandpaper to the brush handles (and getting rolled up sandpaper stuck inside a thin plastic tube is VERY difficult to remove, let me tell you...). Can anyone offer me any help on this?
- take a wood dowel make a cut in one end for a flap of sand paper to fit in, attach loose end to a drill , turn it on run plastic tubes back and forth on sand flap [make a sanding rod]
- Q: My mother is staying with me for a few weeks and was recently put on oxygen, which means a lot of clear plastic tubing. My one cat loves straws and rubberbands. I thought she was ignoring it but she chewed and ruined a long line. Does anyone have some behavioral techniques I can use to stop her from doing this? Thanks so much!
- Make a loud noise to startle the cat whenever she tries 2 chew on the tubes, or a spray bottle would work if u spray them when she tries.
