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: What are the advantages of using plastic tubes in the electronic packaging industry?: There are several advantages of using plastic tubes in the electronic packaging industry. Firstly, plastic tubes are lightweight, which makes them easy to handle and transport, reducing shipping costs. Secondly, plastic tubes provide excellent protection against moisture, dust, and other contaminants, ensuring the safety and longevity of electronic components. Additionally, plastic tubes are customizable, allowing for various sizes and shapes to accommodate different electronic devices. Lastly, plastic tubes are cost-effective compared to other packaging materials, making them a cost-efficient option for the electronic packaging industry.

Q: Can plastic tubes be used for electrical wiring?: No, plastic tubes cannot be used for electrical wiring as they lack the necessary insulation properties to safely carry electrical current. Electrical wiring typically requires materials such as copper or aluminum conductors with appropriate insulation to meet safety standards.

Q: Can plastic tubes be used for DIY hydroponics systems?: Yes, plastic tubes can be used for DIY hydroponics systems.

Q: Can plastic tubes be used for transporting gases?: Yes, plastic tubes can be used for transporting gases. Plastic tubes are commonly used in various industries for this purpose as they are lightweight, flexible, and resistant to corrosion. Additionally, plastic tubes can be easily customized to meet specific requirements, making them a versatile option for gas transportation.

Q: i finally bought a new faucet, and changed it. it seems that there is no more leaking from the faucet.but now, it seems that there is some water leaking right under that white plastic screw. around the plastic looking tube. inside of it, there is a dark rubber kind of ring around it. i can't take out the white plastic screw (i don't know the those special names.) otherwise, i will just put some plastic tape, and seal it. that shouldn't be so hard. so my question is 1. what do you recommend? should i buy a new tube? or is there any other way to fix this thing?extra question.2. the new faucet has the top iron thing and a black plastic base. i put the plumb's putty on the edge of top and bottom of the black plastic base. i am thinking what if there are some water leaking inside of the faucet, if i sealed the whole plastic base, the water will accumulate inside of it. did i do the right thing at all?: Looks like the plastic connector has a duff washer in it. It will keep weeping and its annoying. PTFE plastic tape may assist but to be fair id do this: Remove the tube and make sure the threaded brass tail of the tap is flat and smooth wioth no burrs. Second, make sure the threads on the tube arent frayed or have been cross threaded so it goes on slightly crooked. third, make sure the black rubber washer in the tube connector end isnt twisted, split or slipping inside the tail when tightened up fully (common with some makes) fourth, make sure you havent overtightened it, this can cause the above. fifth, where the white plastic braded tube meets the shiny metal crimp section (before the white plasic) it can sometimes fail. Manufaturing fault but not uncommon. Done worry about your question 2. Its 99% question 1. Plumbing and heating engineer for 12 years - a little tip - if you have to force it, your probably doing it wrong. Its a good motto for plumbing.... and in life!!! Yeah baby! Good luck

Q: If a kid has to be intubated due to a respiratory infection, what do they do? Do they keep you asleep until you can breathe on your own while you're intubated or can you be awake while the tube is in? How long do they usually leave it in? How do they put it in if you're in respiratory distress?: When someone needs to be intubated, they place narrow plastic tube down into their throat, just above the patients lungs. This can be done in respiratory distress. How long the tube stays in place all depends on how sick the patient is. That can be days to weeks. The patient is usually sleeping to help them breath more easily with the ventilator, but if someone is able to remain comftorble, they may allow them to be more awake.

Q: Where can i get a spare light saber blade(just the tinted plastic tube)a phone # or url would help?: I okorder does conversions they put in a stronger removable blade specifically for dueling. So if you use your Force FX for fighting. they will be a great place to go. They have many different kinds of blades so you will need to contact them for what you need specifically.

Q: I have a hole ins a plastic tube that contains water how do I seal the hole?: You may find that you could A: use a water bed repair patch and than wrap tightly with duct tape or B: get a tube of some silicone like they use to repair aquariums. apply liberally and than wrap with plumbers tape. Let it dry as good as possible before putting any real force to it. Good Luck!

Q: What are the different end closures available for plastic tubes?: There are several different end closures available for plastic tubes, including screw caps, snap-on caps, flip-top caps, pump dispensers, dropper tips, and squeeze dispensers.

Q: Does the PVC-U drain plastic pipe need to be fabricated and installed?: PVC-U plastic drainage tube placement should be calculated or not should be laying pipe support method, pipe diameter and special credentials resettlement environment and position to determine the situation: 1, laying underground drainage pipeline laying is not needed to calculate; includes 2 stent drainage pipeline, resettlement quota items should not be calculated. 3, debugging, placement, stability methods, such as integrated pipe laying, drainage pipe support or hanger, need to extend the distance of the support and hanger should be converted to increase.
