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: Are plastic tubes resistant to cracking?: Yes, plastic tubes are generally resistant to cracking due to their flexible and durable nature. However, the resistance may vary depending on the type of plastic used and the specific application of the tube.

Q: Is it OK to drink water with plastic pipes at high temperature?: If used in high temperature conditions, may cause performance instability, there is a certain risk. Only plastic pipes which meet the requirements of high temperature can be used.

Q: What is the expansion joint in the drain pipe?: From the connection mode, there are welded connections, expansion joints, flange connections, telescopic joints, loose sets, connections, expansion joints

Q: What are the common diameters of drainage plastic tubes?: The common diameters of drainage plastic tubes range from 2 inches to 6 inches.

Q: Is it acrylic or is there some other that wont shatter?: If okorder /... Hopefully this helps!

Q: Do plastic tubes have any limitations in terms of moisture resistance?: Yes, plastic tubes do have limitations in terms of moisture resistance. While some plastic materials used in making tubes may offer good moisture resistance, others may be more susceptible to moisture absorption or degradation over time. Factors such as the type of plastic, thickness, and manufacturing processes can influence the level of moisture resistance. It is important to consider these limitations when choosing plastic tubes for applications where moisture resistance is critical.

Q: I'm Assistant Directing a production of Hairspray! and need to find a piece of tube that a person can stand inside of for the Giant can of Ultra Clutch Hairspray. We thought to use huge cardboard tubes from Home Depot but the largest size they had was only 1' diameter. Corrugated plastic tubes wont work, it needs to be smooth like PVC or cardboard. A wood tube would be okay too: If it exists try Broward Paper in Fort Lauderdale but 36 Diameter is real wide Maybe Ikea has something made from a light weight wood that is used as a table base

Q: Can plastic tubes be used for fluid transfer in manufacturing processes?: Yes, plastic tubes can be used for fluid transfer in manufacturing processes. They are commonly used due to their durability, flexibility, and resistance to corrosion and chemicals. Additionally, plastic tubes offer cost-effectiveness and can be easily customized to meet specific application requirements.

Q: Can anybody tell me what the plastic tubes/lines are that run along the under body of my 2003 GLI? I was driving down the highway the other day, and a Semi truck dropped a big chunk of ice off of it and I took a shot to my under body. When I got home I checked under neath and notice it dented my fuel filter pretty back and pinched a white plastic hose that was next to the fuel filter. I followed the line and it goes into my rear pass. wheel well. I looked in the owners manual but I can't find anything on these lines that are under there. Some are blue and some are white. Anybody know what it is? I unkinked the hose and everything seems to be running fine, I'm assuming it's some type of vent, maybe for the gas tank, but I've never seen anything like this before, and I'm kind of confused why they would run something like that under the body of a car that sits so low to begin with. I would really like to know what these lines are. Thanks!: Ok, There are three lines one black white and green! Two are fuel lines one is fuel feed line and the other is return line to the tank! The other is a vent line or evap line! So I would check them out very closely for damage! If you look under your hood to the right of the coolant bottle are said lines you can follow each one ond see where it goes and what it goes to! Hope this helps.

Q: Can plastic tubes be used for agriculture applications?: Yes, plastic tubes can be used for various agriculture applications. They are commonly used for irrigation systems, where they efficiently deliver water to crops. Plastic tubes are also used for hydroponics, allowing for the controlled growth of plants without soil. Additionally, they can be used for protecting young plants from pests and extreme weather conditions.
