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's the outer diameter of the 1 inch 2 tube?
Equivalent to the usual 1 to 7 charge, smaller sizes are represented by 1/16, 1/32, and 1/64, units or inches. If the denominator and numerator to elements (such as 2, 4, 8 molecules, 16, 32) have to.The inch is shown in the upper right corner by two, such as "1/2""For example, DN25 (25mm, the same below) water pipe is the British 1 "water pipes, but also the previous 8 water pipes.".DN15's pipe is the water pipe of the British 1/2, and it's also the 4 water pipe.For example, the water pipe of DN20 is the water pipe of the British 3/4, and it is also the 6 water pipe in the past
Q:the teacher in item 5 needs to order plastic tubing.if each of the 60 students needs 750mm of tubing?
1000 mm = 1m 60*750mm(1m/1000mm) = 45 m best answer?
Q:Plastic pipe for concrete wall column
This should be a heat pipe or a temperature measuring tubeMass concrete of thickness greater than 1m, in order to avoid excessive build-up of temperature due to hydration heat of cementUsually need to set up cooling water pipe, concrete pouring, cold water in the pipeline to achieve cooling effectThe temperature measuring tube is used to measure the temperature inside the concrete and is often used as a temperature measuring conductor
Q:i plan on getting a syrain hamster are critter trail cages safe for them with tubes?
Well, I have a syrian hamster and he has a Habitrail Ovo Studio. The tubes are bigger than the Crittertails and he walks through the tubes without even touching them. it was an expensive cage, but definatly worth it
Q:How do i get a plastic bottle cap out a bottle cup sized hoover tube?????
If the part of the tube where the cap is lodged is all metal for 8-10 inches in either direction, try heating it up. Position the tube on the reverse port, leave the vacuum off, then heat the tube to the point of weakening and distorting the cap. Then turn it on and blast that sucker out. WARNING: This method may very likely destroy your hoover!
Q:Where can I buy the big coloring posters that come in plastic tubes?
I am not sure of the size but you can find some at Office Depot or Office Max. You can also try a toy store like Toys R Us.
Q:Ear Tubes?!?!?!?!?
I never had tubes, but my son did. They are tiny plastic tubes that your ears will push out over time as they grow. You will not feel them at all, and if you want to swim, you just have to put some swimmer's ear plugs in, which you can buy at the drug store to seal your ears shut. My son used that and he swam all the time with no problems. You'll be fine!
Q:can u keep 6 goldfish in a plastic goldfish tank with out the air tube?
depends on the size of the tank I would say just move them to a bigger tank or put more plants in the tank.
Q:What is a Paintball Power Tube used for?
The power tube is the part that holds the valve in the marker and helps direct air flow. Getting a new power tube will do NOTHING to performance. It has no performance valve what so ever. The front bolt is the part that helps push the ball out or the chamber. And getting a new one will help very very lil. So lil that it doesn't really matter. THis is because the stock front bolt on the tippmann markers is made so well that changing it doesn't make it any better because they will perform just about the same. Replacing the stock power tube to a full aluminum power tube is a good idea because after a while the stock plastic power tube does tend to break and when that happens it will cause air or co2 to leak. The aluminum one wont do that and lasts a lot longer.
