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 pneumatic systems?: Yes, plastic tubes can be used for pneumatic systems. Plastic tubes are lightweight, flexible, and resistant to corrosion, making them suitable for transporting compressed air or gases in pneumatic systems. Additionally, plastic tubes are cost-effective and easy to install, making them a popular choice in various industries.

Q:Is there an easy way to remember the color tubes (phlebotomy) and what test they are needed for?: I don't know of an easy way to remember the tube types and tests. Its just something you have to work on - though it does come pretty quickly. Another important item is the draw order of the tubes. It's very important to ensure that tube contents don't contaminate subsequent tubes and cause erroneous results.

Q:Can plastic tubes be used for bottling medications?: Yes, plastic tubes can be used for bottling medications.

Q:How do plastic tubes perform in high-humidity environments?: Plastic tubes generally perform well in high-humidity environments. They are resistant to moisture and do not rust or corrode like metal tubes. However, it is important to choose the right type of plastic material that is specifically designed to withstand high humidity conditions to ensure long-term durability and performance.

Q:Home decoration, the wire is a set of PVC tube or galvanized steel pipe? Why?: Home appliance wiring in the dark needed for the electric tube, according to the needs of different needs to choose, whether it is PVC, galvanized steel pipe or iron pipe, you need to choose on demand.

Q:How can I make plastic pipes harden quickly?: If you need to keep the PVC tube well, you can use that kind of sealed bag with a quilt and squeeze the air inside. It's OK,PVC plastic because of low temperature and harden, do not need to worry, when the temperature picks up, will naturally restore the original hardness.

Q:How do plastic tubes compare to rubber tubes in terms of elasticity?: Plastic tubes generally have lower elasticity compared to rubber tubes. Rubber is known for its high elasticity, allowing it to stretch and return to its original shape easily. Plastic, on the other hand, tends to have limited elasticity and may not stretch as much as rubber.

Q:Are plastic tubes resistant to warping under high temperatures?: No, plastic tubes are not typically resistant to warping under high temperatures.

Q:I'm trying to hang a picture.: I think you mean the anchors. They are used when your wall is plasterboard and you can't find a stud to screw/nail into. Putting just a metal screw into plasterboard does not have much strenght for hanging things. The plastic anchor helps spread out the load.

Q:Im working on an art project right now and I want to buy some 4ft long T8 Blue light bulbs. But I cant seem to find any US companies selling them.
