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: 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: Can plastic tubes be easily labeled or branded?: Yes, plastic tubes can be easily labeled or branded. They provide a smooth surface that allows for clear and durable printing of logos, text, or any other desired branding elements. Additionally, various labeling techniques such as adhesive labels, screen printing, or direct printing methods can be used to customize and brand plastic tubes efficiently.

Q: How do you remove labels from plastic tubes?: One way to remove labels from plastic tubes is by soaking them in warm soapy water for a few minutes. Afterward, gently scrub the label with a sponge or a soft cloth to peel it off. If any residue remains, you can use rubbing alcohol or nail polish remover on a cotton ball to remove it.

Q: Can plastic tubes be used for oil and gas industries?: Yes, plastic tubes can be used in the oil and gas industries. Plastic tubes, specifically those made from high-density polyethylene (HDPE) or polyvinyl chloride (PVC), are commonly used for various applications in the oil and gas sector. They are suitable for transporting fluids, chemicals, and gases due to their resistance to corrosion, chemicals, and abrasion. Plastic tubes can offer cost-effectiveness, durability, and ease of installation, making them a viable choice for certain oil and gas industry needs.

Q: What industries use plastic tubes?: There are several industries that use plastic tubes, including plumbing, construction, manufacturing, automotive, pharmaceutical, and food packaging industries.

Q: I'm going to make manicotti and the recipe calls for a stuffing tube. Can I use a spoon or maybe a plastic bag with a tip cut off?: Another method that works when the plastic bag idea doesn't is a cookie dough press. Just fit one of the tips on the end, load it up with your product, and press the product into what you're stuffing. I find this works extremely well when making stuffed, thick cut pork chops.

Q: My 2000 ford focus broke down last week and me and a family friend determined its the fuel pump so as we were replacing it we noticed the nozzle hooking into the top of the fuel pump was snapped it is connected to a hard plastic tube and I need to know either what the tube is called or what the nozzle is called PLEASE HELP!!!: You will notice the quick disconnect line is disconnected from the fuel pump housing. It should be able to be bought at a Ford dealer separate from the hanger, if your auto parts place does not have a repair kit for Ford quick disconnects.

Q: Can plastic tubes be used for DIY crafts?: Yes, plastic tubes can be used for DIY crafts. They are versatile materials that can be easily cut, shaped, and glued to create various craft projects such as jewelry, wind chimes, planters, and even sculptures.

Q: PVC flame retardant pipes have three kinds of ABC, heavy duty is not rigid flame retardant tube?: Pipe length 4m/ root, the color is white, pure white, bending needs special bending spring. Pipe connections using special joint insertion connection, the connection with the special surface coating adhesive, sealing interface.
