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 tube flies? Where can you get them?
if you are talking about tying your own anglers workshop online has many materials to choose from.
Q:How do you securely connect a plastic tube to a male threaded fitting?
You would be looking for a Compression fitting that is suited for plastic tubing. Ask at your hardware store.
Q:what are those 5-6ft light stand up tubes filled with water with a bubble and light affect?
I know just what you're talking about, in fact I used to have one. I figured you could find them just doing a google search, but no, there doesn't appear to be anything out there. I suspect the company went out of business.
Q:What are some things to buy to take the focus off going to the register with only a tube of Preparation H?
Buy some boxes of jello, a large bowl, a large meat fork and some live goldfish.
Q:How can I rescue a plastic tube flushed down the toilet?
Wet vac! Or else it's gone!
Q:what kind of tube do they put in people's ears?
I believe the best way to protect your ear from getting water in it is to purchase moldable wax like ear plugs. It's cleaner and safer than cotton mixed with vaseline which may clog the tube and attract dirt in the ear canal. They are fine for swimming and showering.
Q:Where can i get a spare light saber blade(just the tinted plastic tube)a phone # or url would help?
I okorder.com 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:will the vapor from weed melt a plastic tube?
It's a great source for more information about the many benefits of portable herbal vaporizers.
Q:2. Two identical strong magnets are dropped simultaneously by two students into two vertical tubes of the same?
hi Ducky, Hehehehehehehehehehehehehehehehehehehehe... i admire this one..the place IS GOD!!! which will coach those boys a element or 2..a huge celeb My pal.. a chum, poppy1 happy Easter My friends..shop a especially Easter Egg for Me. Lol..
Q:Do Chap Stick tubes need to be so long? Aren't they a waste of plastic?
There are so many other problems in this world. Bigger ones. Plastic is plastic man. If the tube was half the size, that's half the stuff, so you'd buy twice as much. Same amount of plastic. More work in production. Pointless. *shrugs*
