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: it comes this plastic tube (it isn't in the pic) but i have no idea where it goes or what is it for?: Does the tube you're referring to have a little hole in it? If so it's for hooking up an airline to help oxygenate the water.

Q: Do plastic tubes require any special handling or storage?: Yes, plastic tubes may require special handling and storage. It is important to avoid exposing them to extreme temperatures as they can melt or become brittle. Additionally, they should be stored in a dry and clean environment to prevent contamination. It is also advisable to handle them with care to avoid any physical damage that could compromise their functionality.

Q: I recently bought a '95 C220, shes my first MB and after a week of driving I have vowed to never buy any other brand of car. I think i've just about figured out all of her idiosyncricies, however this one still confuses me. There is a small 1/4 diameter or so plastic tube comming out of the floor to the left the battery/fuse box in the trunk, about 8 inches long or so. It has an L connector on the end, but it is not fastened to anything, nor can i find anything that it could fasten to. Any clues anyone? Vaccume tube for some component that was never installed?: it goes to the battery as a vent....but since your car is older.....it probably had a replacement one without the need for it . the OEM battery was not a sealed top

Q: How about plastic pipes for water pipes in the house? With PVC or PPR or something?: PVCPVC pipe is divided into PVC, water supply and drainage pipe two kinds, with better tensile and compressive strength, but its flexibility is not as good as other plastic pipes. Used for municipal water supply and drainage, industrial water supply and drainage, civil water supply and drainage, irrigation, vegetation watering, etc..

Q: Are plastic tubes suitable for use in the pharmaceutical packaging industry?: Yes, plastic tubes are suitable for use in the pharmaceutical packaging industry. They offer several advantages such as being lightweight, flexible, and easy to handle. Plastic tubes also provide excellent barrier properties, ensuring the protection and preservation of pharmaceutical products. Additionally, they can be customized to meet specific requirements, such as tamper-evident features and child-resistant closures, making them a popular choice for pharmaceutical packaging.

Q: Are plastic tubes transparent?: Yes, plastic tubes can be transparent.

Q: I have a fairly old A/C unit in my home. Thanks to my lovely new puppy's curiosity a white tube running from the unit into the house is now broken. It appeared to be a plastic tube about an inch or so in diameter. What is this tube for and what would be the easiest method of repairing it? It is broken clean off and there is now about a 10-14 inch piece missing.: That is a drain tube that comes off your unit and drains codensation outside. To repair it just cut it off, get a coupling, glue it in one side then however long a piece you need on the other side.

Q: Can plastic tubes be used for food and beverage applications?: Yes, plastic tubes can be used for food and beverage applications. However, it is important to ensure that the plastic used is food-grade and meets all necessary safety standards to avoid any potential contamination.

Q: How is dialysis tubing different from the plasma membrane? Give two reasons.: dialysis tubing is a thin plastic tube that is compared to the plasma membrane. dialysis tubing is not a part of cells, it is a plastic prop used for experiments such as testing selective permeability. so there alot of differences, the main one being that the plasma membrane is actually in cells, where as dialysis tubing just reinacts what the cell membrane does.

Q: How do you prevent plastic tubes from warping in direct sunlight?: One way to prevent plastic tubes from warping in direct sunlight is by using UV-stabilized plastic materials. These materials contain additives that protect the plastic from the harmful effects of UV rays, ensuring that the tubes maintain their shape and integrity even when exposed to sunlight for extended periods. Additionally, providing shade or covering the tubes with a protective layer can also help prevent warping by reducing the direct exposure to sunlight.
