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:how do i make an artillery shell tube?
Sounds like you're abort ready to kill yourself. It's hard to tell what you're talking about. An artillery shell wouldn't have 6 shots it might have a cluster of 6 smaller bombs. hdpe is a type of plastic dont build anything out of plastic that is just stupid. Do you have a picture of what you're talking about? Are you talking about some type of firework(i hope)? OR some civil war artillery shell? Or something else modern ? One of my hobbies is building firearms and other fun projects I can tell you right now this sounds like bad news. I wouldn't play with anything like this. If it's what i think it is.
Q:Remove brass connecter from plastic water tubing?
your best bet is to use a dremal with a metal cutting disk you need a steady hand and you will be able to cut at the rings until you can just snap them with your hand then bend it open and pull it off the tubing. if you don't have a dremal you should be able to get one for around 40 bucks and 5 bucks for some metal cutting disks.
Q:Is it safe to use drain opener in sinks that have plastic tubes?
PVC pipes used for plumbing are very acid resistant I read a while ago that most pipes will be resistant to 99% pure sulphuric acid, (I had a crazy notion about a year ago to make lead acid batteries using pvc pipe for the cells) so the chemicals won't damage the pipe, but if it builds up pressure and the pipes are old and starting to get brittle there is a chance the pressure and heat from the chemical reaction might burst or crack the pipes.
Q:How can I train my cat not to chew on oxygen tank tubing?
Spray bottle or make loud noise when cat does the behavior the cat should take off if you do this every time the cat should get the point soon enough
Q:I know there are two kinds of plastic pipes: thermoplastic pipe and thermosetting plastic pipe. PPR what kind of plastic pipes do you have?
Individuals do not feel where great harm, but also caused by bad habits.PPR no poison, a little basic chemistry knowledge, but also know that the chemical composition of PPR is not poisonous.
Q:Where can I buy inexpensive plastic tubes?
Lowes; you can buy plastic plumbing in 10 foot lengths and different hole sizes too. they will cut them if you ask, but you can do it yourself with an electric knife or small hand saw. I bought them for extra long windows and used them as drapery rods.
Q:What is the strongest cast tube plastic?
polybutylene or chlorinated polyvinyl chloride
Q:Which control method would NOT be suitable for killing mycobacteria in a capped culture tube?
If it were a Glass tube the answer would be A. UV Light does not go through glass well and would not kill much. If it is a plastic tube, D.
Q:Dialysis Tubing HELP!!!?
