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:I once saw a tunnel tube part that is just a small flat part with holes in it. It would allow you to connect, say, two cages together and allow the hamsters in those cages to see and smell each other but NOT pass through. I have been looking for this part but I cannot seem to find it again. If anyone has a website, I would appreciate it very much: you're turning out to be a multitude and it will stink i does no longer do it sounds cool yet nasty all the way around you mustn't be waiting to get the hamster poo or pee up out of the flooring partitions tubes think of of ways your homestead will scent

Q:Just curious, when there is only a bit of toothpaste left, I have to squeeze little by little from bottom up. But then after using it, I'll have to do the same thing next time around. Obviously the toothpaste has to settle down the tube. Why and how does it do that?: The plastic material has internal stresses that retain the shape it was cast in originally. Since it is attached to a round head it tends to form a sort of flattened cone. The toothpaste moves back up the tube to fill the available space as it is a type of really thick fluid. The shape may also lead to the toothpaste moving upwards due to capillary action (similar to how water moves up a very thin straw) To combat this effect, you can buy a little squeezy thing that rolls over the tube to prevent the toothpaste from moving backwards, or you can fold/bend it over as you use it like many people do. I store mine upright on the cap so the toothpaste settles at the end I squeeze it out of. The tube also uses less counter space when you store it upright as compared to laid over on its side.

Q:Can plastic tubes be used for wastewater treatment plants?: Yes, plastic tubes can be used for wastewater treatment plants. Plastic tubes, such as PVC or HDPE pipes, are commonly used in wastewater treatment plants for various purposes including transporting wastewater, distributing air in aeration tanks, or transferring treated water. Plastic tubes are preferred due to their durability, resistance to corrosion, cost-effectiveness, and ease of installation.

Q:Plastic pipe joint leakage of water can be done with glue: Not recommended, you are the water inlet pipe, the water inlet pipe is confined to, even if you use the glue water well, did not leak, soon will leak, you do not know what is the tube, a live connection in Water Leakage place

Q:This is for silver eagles, silver maple leafs, and silver rounds that i have stored in plastic coins tubes. I have been using cotton balls stuffed into the top to take up air space and prevent sliding around; but will this damage the silver?: Cotton balls work fine, and won't damage the silver IF they are clean and you don't shake the tubes a lot. (Coin companies use cotton balls when shipping coins in tubes if needed.)

Q:Can plastic tubes be used for transporting gases?: Yes, plastic tubes can be used for transporting gases.

Q:Are plastic tubes suitable for display stands?: Yes, plastic tubes can be suitable for display stands. They are lightweight, durable, and versatile, making them ideal for various types of displays such as signage, banners, or product displays. Plastic tubes can be easily customized to different sizes, shapes, and colors, offering a wide range of design possibilities for display stands. Additionally, plastic tubes are often cost-effective and easy to assemble, making them a popular choice for both temporary and permanent display solutions.

Q:Can plastic tubes be used for electrical wiring?: No, plastic tubes cannot be used for electrical wiring as they do not provide adequate protection and insulation for the wires.

Q:i have 200$ to spend i am 90 lbs and 4 foot 11 inches. I want to know what i should get-- this float tube: I have used a float tube for several years and regularly fish with a friend who has a pontoon, if you have the money, go for the pontoon. I love my float tube and it does the job, but I bought it because I'm too cheap to get the pontoon. The pontoon, keeps more of you out of the water (great here in northern regions to stay warmer longer), comfortably carry more gear, and are more manuverable, overall a better choice

Q:How do plastic tubes compare to silicone tubes in terms of flexibility?: Silicone tubes are generally more flexible than plastic tubes.
