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: The dishwasher behind my bar at work has a leak. The pipe that's leaking is Parker Parflex PP 3/8 plastic tubing that connects into a metal nut and brings clean water in. The pipe has a leak exactly where it meets the nut, so in theory I could cut off the cracked portion and then re-seal it to the nut. Can I cut it with wire cutters? Should it be sanded after I cut it? Do I use a teflon sealant? Thanks for any help!: That should be a compression fitting. If it's a brass fitting then they are one time use. You can get a new brass fitting, cut the PP tube clean with a knife or a razor blade - be careful not to cut yourself please, then install the nut over the tube, slip the compression ring over the tube and if there's an insert that goes inside the PP, insert that. Then push the hose into the fitting and slide the nut and ring to the threaded portion of the fitting and tighten it. Be careful to tighten it enough to seal but not so tight you cut through the pipe again. It's likely the reason you have the leak in the first place is because someone overtightened it. OR you can simply buy a replacement hose. I'd prefer a wire braid shielded pipe. Stronger and made with a professional fitting on the end, one you don't have to mess with. My opinion, replacing the tube is the better idea. And they're not stupidly expensive either. Good luck with your project. '')

Q: Can plastic tubes be used for waste management systems?: Yes, plastic tubes can be used for waste management systems. They are commonly used in various applications such as sewer lines, drainage systems, and underground piping for transporting and managing waste materials effectively. Plastic tubes offer advantages such as durability, resistance to corrosion, and ease of installation, making them suitable for waste management purposes.

Q: I need it fast, so I want to just go and buy it - no time for shipping.: a plumbing supply house. it's not common but they do use it for pneumatic tube systems for delivering things in capsules, like the bank and pharmacy uses on their drive-thru.

Q: Hey i am looking for solid tubing because i am trying to construst a Gravity Vortex Bong i am looking for two tubes which i can use as the two chambers. I am wondering which stores will carry then because i have checked home-depot and Michaels craft store. Neither of them ahve what im looking for. I am unable to purcase somthing offline.: tap plastics has exactly what your need

Q: Can plastic tubes be used for storing cleaning agents or detergents?: Yes, plastic tubes can be used for storing cleaning agents or detergents. Plastic tubes are commonly used for packaging various products, including cleaning agents and detergents, due to their durability, flexibility, and resistance to chemical substances. They provide a safe and convenient container for storing and dispensing these products while ensuring their quality and preventing leakage.

Q: Where can I find plastic tubing that is durable, and about a half-inch in diameter? Preferably from some place like Wal-Mart?: I dunno...maybe Walmart??

Q: Which drain is more effective, plastic pipe or concrete drain?: The same effect, that is, plastic pipe easy to build a little, concrete drainage pipe construction more trouble, plastic pipe on your point, concrete drain pipe is cheaper.

Q: While changing the toilet paper my daughter accidentally flushed down the toilet the inner rod that goes through the cardboard tube to keep the roll in the holder. Unfortunately it’s large enough to cause a blockage so I need to get it out. It’s also made of hollow plastic, and will float – so the fact that I can’t see it means it is at least on the other side of the U-bend. A wire hook won’t help, there’s nothing to hook on to. How can I get it out?: Wet vac! Or else it's gone!

Q: How do plastic tubes compare to acrylic tubes in terms of transparency?: Acrylic tubes are generally more transparent than plastic tubes.

Q: What is the maximum diameter-to-length ratio for plastic tubes?: The maximum diameter-to-length ratio for plastic tubes can vary depending on the specific type of plastic and manufacturing process used. However, in general, plastic tubes typically have a maximum diameter-to-length ratio of around 1:100 to 1:200.
