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?
The diameter of the pipe refers to the inside diameter of the tube. Because the wall thickness is different, so the outer diameter is also different1.2 inch internal diameter of about 32mm, outer diameter of about 42.25mmPipe dimensions (British and metric tables)
Q:how we can design a simple total head tube?
A tube with an open ends and connected straight (at right angle) into the side of a pressure container like a pipe or a vessel is called a piezometer. Fluid will rise in the tube equivalent to the static pressure in the container. In a pipe the fluid will probably also be moving and so will have some dynamic energy. If the tube tip has been bent 90 deg. and inserted ( preferably to the center) so that active end is facing upstream, the impact of the moving fluid will convert to additional height of fluid in the tube so that the total head will be the sum of the static equivalent plus the velocity equivalent in feet or meters. That tube is sometimes called an impact tube. The best arrangement is to close the active end of the tube and drill a hole at 90 deg near the end. This allows for the straight tube to be more easily inserted through a small round opening with a sealing gland to stop leakage. This short part can be metal and a clear plastic or glass tube extension fitted to it. A Pitot tube is a combination of the two types of tube and is commonly utilized to measure velocity by subtracting the two heads. It is used in any fluid, water or air, open or contained. However, the Pitot like most other pressure devices usually employs a gage rather than open tubes. The open tubes will limit the amount of pressure to be measured because for each pound of measured pressure (psig), water will rise 2.31 feet.
Q:Plastic Tube in my Lawn?
sounds like a drain pipe for water if and when you get heavy rain...
Q:Does anyone know where I can get an aluminum or plastic square tubing with a 0.5 inch nominal diameter?
McMaster-Carr okorder.com is usually where I go if you need a small length. Almost everywhere you go has a local steer supplier though, they can probably help you out and you can help local business! You might want to re-phrase your question though square tubing with a .5 inch diameter doesn't make a whole lot of sense, but I think I know what you mean.
Q:How much should it cost to replace the Mass Airflow tube on a 2000 Mazda Protege?
the position do you stay? i'm getting my aspects from certi in good structure or nicely in good structure .... search for aftermarket body aspects or merely bypass to a salvage backyard.... round a $one hundred ok because you stay at Wichita, KS i'm effective you does not favor to force to Kansas city because it is the nearest area for Certifit vehicle aspects yet you'll get one on OKorder for $one hundred and free delivery, it is best for you except you are able to contact some salvage yards on your section and likely hit upon a used one which suits your colour. if you're uncertain in case you are able to or can't replace this bumper via your self and also you do not favor to spend a ton of $$ then submit an upload on craigslist lower than gigs/exertions and grant someone like a $one hundred to go back and replace it and that i'm effective someone will do it because it takes about 0.5-hour in case you recognize what you're doing. sturdy success.
Q:What are those painos with a tube in them called?
An organ?
Q:Is the PVC tube a plastic tube or a plastic tube?
PVC is a VCM monomer (vinyl, chloride, monomer), in the peroxide, azo compounds and other initiators; or under the action of light and heat, polymerization by the principle of free radical polymerization of polymers.
Q:Can you catch re-catch chlamydia through a metro gel tube?
Relax, you're fine. A woman indeed may reinfect herself with chlamydia, but don't worry, this condition can be completely prevented. Chlamydia is sensitive to heat, the pathological bacterium can only live for 5~10 minutes in degree 50~60. Plus, away from our body, pathogen of chlamydia will die soon. Except for intercourse, clamydia can spread through sharing the infected toys. And for a certain condition, a pregnant woman can give chlamydia to her baby. Anyhow, do not have to worry about it, you'd be ok!
Q:How do you connect the white plastic tube with the PPR tube?
After heating, the quicklyinsert pipe joint exerts light pressure.Any deviation shall be corrected immediately after insertion in order to avoid any pressure at the weld.Allow combined cooling and cooling time for the given table.This type of connection ensures perfect sealing even in harsh workCondition. BER can be activated to make future federation.
Q:can water colors come in tubes?
Yes, okorder.com/... I hope I've been of some help. Artist and Designer, U.S.
