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:Intubation due to respiratory infection?
When someone needs to be intubated, they place narrow plastic tube down into their throat, just above the patients lungs. This can be done in respiratory distress. How long the tube stays in place all depends on how sick the patient is. That can be days to weeks. The patient is usually sleeping to help them breath more easily with the ventilator, but if someone is able to remain comftorble, they may allow them to be more awake.
Q:Why did they quit making pink plastic tubed popsicles?
Pink still remains the Fla-vor-ice brand's most popular flavor ( punch ). I can find no information on the possible retirement of that flavor. I think that would be silly to retire your most popular flavor. That is my daughter's favorite too. In our last box of 100, they had some in it. But if you switch to the tropical box it is a different set of flavors.
Q:Can plastic pipe be adhered with PVC?
Plastic pipes can be adhesive with PVC glue.PVC adhesive for launching water has the advantages of simple operation, high bonding strength, good sealing performance, cold resistance, heat resistance and strong dielectric resistance.
Q:What sensors can be used to measure changes in the water level in a transparent plastic pipe?
A magnet can be considered to be wrapped with foam plastic to float on the surface of the water. It is placed inside the transparent plastic tube, and a magnetic reed switch is used outside the plastic tube to induce the magnetic field switch.
Q:My antenna on my Nitro Rustler 2.5 ripped off at the top of the plastic tube, is that bad?
Better get it replaced. Don't try to run it with the proper length antenna. You won't have any range and the truck will go out of control.
Q:Reinforced plastic pipe is high density polyethylene PE pipe to enhance it
This is not necessarily.The plastic pipe has many kinds, such as PE, PP pipe, PVC pipe, glass pipe and so on, there are many methods to enhance
Q:PR plastic tubes, everyone said, permanent, a great harm to health, even drinking water is a problem?
1) change the water pipe: the longer the PPR pipe is used, the greater the poison, or the regular flushing and disinfection of the old pipe.2) install pre filter and cabinet water purifier in old pipe line3) new home water pipes customers can study in Europe and the United States, the family installed plastic copper pipe (slightly higher price) or lined with copper PPR tube (moderate price). Because copper has excellent sterilization function and self-cleaning function, it is most suitable for family use.
Q:what can I do to control the toothpaste for a one way flow to the tube exit orifice?
use a rolling pin to squeez the stuff out...and there is a gadget on the market that looks like 2 fingers, you slip the bottom of the tube between the 2 fingers and just turn up so that the tube rolls around and over the fingers and the paste doesn't backflow..got he idea?..but you can always by toothpast in a pump
Q:What is this tube near the battery/fuse box in my w202?
yep it is for the battery, look for a hole in the side of the battery towards the top of it. if it is a genuine mercedes benz battery it will have the hole. some aftermarket batterys have it and others dont. it is ok to leave it disconnected it will not affect how the car functions
Q:How do I reach the plastic tubing where it attaches to the water dispenser in the door of my fridge?
there is almost always a screw located behind the water bar that you can remove the push levers than you will see the other screw to remove the plastic front cover the problem is usually more than tubing pulling off it is more likely a broken part however you can get almost any part from frigidaire ?? less than a year isnt it under warrantee?? dont try to open it if it is that can void your warrantee
