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: I remember big coloring posters, 24 by 36, that come in a plastic tube so you can roll it up and store it. The big posters came with 10 markers you could use on it, but you could use anything you wanted to color it. Where can I buy those now? I can't find them at Walmart anymore, and there's a really small selection on OKorder.: I am not sure of the size but you can find some at Office Depot or Office Max. You can also try a toy store like Toys R Us.

Q: Do not pipe plastic pipe connection: Buy a metal. With the elbow sealing machine and plastic pipe connected together by threads in the two ends and two pipes on the line.

Q: the tube is running from the cold water tap of the laundry sink. there is always a trickle of water. the tube appears to have been placed in the cement floor at the time of construction. i can think of nothing it feeds. would like to get rid of it but want to know why its there first.: there is probably a sump of sorts that leads outside, pour water down the hole that has dye in it and see where it comes out

Q: i was wondering what would cause oil to lightly spray out of the plastic tube that hangs down out of the top end of the piston. the tube comes out of the top end right before the exhaust header bolts onto the piston.: The link doesn't work - session is timed out. Always give year, make, engine size and model # when asking questions. We need all of that info to give an informed answer. I know what tube you are talking about. That tube is the breather hose for the power valve. As the piston rings start to ware, the oil in the premix doesn't get fully burned and accumulates on the power valve and lt's linkage. The engine is probably overdue for a top end rebuild and power valve cleaning. Remove the cover to see how much crud is in there. 2 stroke engines require rebuilds quite often, to prevent damage to the cylinder. If the top end is fresh, remove and clean the power valve. Otherwise clean the valve and replace the piston rings.

Q: A meat baster consists of a squeeze bulb attached to a plastic tube. When the bulb is squeezed and released, with the open end of the tube under the surface of the basting sauce, the sauce rises in the tube to a distance h, as the drawing shows. It can then be squirted over the meat.Using 1.013e+05 Pa for the atmospheric pressure and 1100 kg/m3 for the density of the sauce, find the absolute pressure in the bulb when the distance h is each of the following.(c) h = 0.140 m Pa=?(d) h = 1.10 10-1 m Pa=?: Meat Baster

Q: What is the maximum temperature plastic tubes can withstand without deformation?: The maximum temperature that plastic tubes can withstand without deformation varies depending on the type of plastic used. Generally, common plastics like PVC (polyvinyl chloride) can withstand temperatures up to 140°F (60°C) without deforming, while more heat-resistant plastics like PTFE (polytetrafluoroethylene) can withstand temperatures up to 500°F (260°C) without deformation. However, it is important to check the specifications of the specific type of plastic tube being used to determine its maximum temperature tolerance.

Q: Can plastic tubes be used for transporting powders?: Yes, plastic tubes can be used for transporting powders. They are commonly used in various industries such as pharmaceutical, food, and chemical industries to transport powdered substances efficiently and safely. Plastic tubes offer advantages like being lightweight, durable, and resistant to corrosion, making them suitable for transporting powders of different types and sizes.

Q: does it matter where you pur the fluid and how much should be poured in my vanhave a radiator caop and then like a long plastic tube that goes down to the engine and says coolant on it...where do i pour the antifreeze??: By the looks of all your questions recently you really seem to be doubting yourself with answers. So quite frankly, I would get someone to help you look into your cooling system problems if you are running hot. Or, stop by a good reputable repair shop for a coolant top-off and maybe a diagnosis of any overheating you may have. Good Luck to you..

Q: how long will cigars keep in tubes?: Cigars are hydroscopic, that means they tend to match the relative humidity of the enviornment in which they are kept. A tubed cigar in a tube that is hermetically sealed outside of a humidor will keep for 3 - 6 months. After that, even the best seal will begin to fail. In a humidor, a tubed cigar hermetically sealed will keep nearly indefinately. In a plastic tube, you may as well not even have the tube.

Q: Fly fishing question, I am taking up the hobby :): Tube okorder in a few weeks. You will find many proven options for many situations. If you want to buy some as a first time tube fly fisher then you will be in good hands. We also have a wonderful tube fly box out. The Tribute tube fly box is new for the 2009-2010 season. You will find this box will hold a bunch of tube flies and you can push heavy cone heads in snug. If you are looking for a gift, this would be great for any fly fisherman. You can also contact Clarke at Puget Sound Fly Company. Besides being a great soccer coach he is well schooled in tube flies. His shop will have some great patterns for you until I am finished the first tubes for the public. Puget Sound Fly Company is one that Irideus tips its hat at for the many long hours testing put in over the years. Good luck, we are all happy to help you get going. Tim Owner Irideus
