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 difference between the plastic thing they put in your nose, an oxygen mask, and a breathing tube?
They're just different levels of helping you breathe. The cannula (the thing that goes in your nose) helps you get a little bit of extra oxygen. The mask comes into play when you really need help, and can give you many different levels of concentrated oxygen. When you can't breathe enough on your own to stay alive, they put a breathing tube down your throat, hook you up to a ventilator, and the machine breathes for you.
Q:melted plug tubes '95 civic?
unless the melted plastic interferes with the new tubes or spark plugs, there is no reason to try to clean the plastic out. if you can get the plugs out and put new ones in and put the wires on with no problem then just leave the residue in there...it won't hurt anything. you are talking about a major undertaking if you want to remove the tubes to clean them. The valve cover has to come off to get to the tubes and the tubes are usually pressed into the base of the head so the head may have to come off as well. you might want to just pull the wires and try to use a rat-tail file down into the tube to scrape away the excess plastic on the inside of the tube (leave the spark plugs in place if you try this so the filings don't get into the engine). Then use a vacuum cleaner to suck the filings out of the tube before you put the wires back on. I'd recommend that as the best thing to do if the burnt plastic is a concern. Otherwise, I'd leave it alone. hope that helps
Q:What glue can I use to glue the plastic in toothpaste tubes, potato chip bags etc?
I use E-6000 clear glue for almost everything. I am a sewer and needed some weights so I used this glue on huge metal washers putting two of them together for more weight. I have had these weights for quite a few years. The trick to this glue is to let is set. According to the label is it flexible, paintable, non-flammable, waterproof, safe for photographs, etc. I would suggest not using this in an enclosed area for any length of time. Good luck - Hope that helps.
Q:Why does a cow magnet go slower through a copper tube than a plastic tube?
A magnet is not attracted to copper, so you might expect that it would not have any effect. But there is another property of magnets to keep in mind: a moving magnet produces an electric field. So, as the cow magnet moves through the copper tube, it creates an electric field that sets up small electric currents in the copper tube. These moving eddy currents in the copper have their own electric fields that work against the field of the magnet. These interacting fields are what slows down the cow magnet. The plastic tube is not affected by the moving magnetic field of the cow magnet, because plastic is not a conductor so no electric field is created in the plastic tube. We are most familiar with a moving magnet creating an electric current in a wire, the way a spinning magnet in an electric generator creates a flow of electricity, but a moving magnet will create an electric current in any conductor. It doesn't have to be a wire, and it doesn't have to be ferromagnetic. Hope this helps a bit.
Q:Can PVC pipes be used with drinking water?
At present, the domestic PVC processing is good and bad, there may be lead salt as a stabilizer for the water supply pipe.It is safe to use PVC water pipes that are not guaranteed by lead salts as stabilizers. Its physical and chemical properties still have advantages in plastic pipes.
Q:What are the raw materials for plastic pipes?
Plastic pipe raw material is plastic particles, according to the pipeline production processing performance requirements, with the different requirements of finished products, there are different manufacturers grades, grades and performance differences.
Q:Why aren't all plastics recycled, such as the plastic tubes that many skin care products come in?

Q:How do I make air flow continuously thru a 1 plastic tube connected to itself using an electric blower?
The problem is not how to connect the blower, the problem is how to get the small ball to go through the blower (which you can't). What you have to do is to deflect part of the air in the tube to the blower input without allowing the ball to go that path. And then the blower pressurizes the air and injects it downstream of the pick off port. A high pressure low volume blower or pump might be best. That means a small pick off port and a small injection port.
Q:securing a hollow tube to a flat wooden surface?
you can try small brackets
Q:are glass blood collection tubes are better than plastic s ?
Not that I know of. Some of the benefits of using a plastic tube is that they are single-use, disposable, incineratable, and doesn't shatter when dropped, all lowering the risk of contamination.
