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 you prevent plastic tubes from discoloration?: To prevent plastic tubes from discoloration, you can try a few methods. First, ensure that the tubes are stored in a cool and dry place away from direct sunlight, as exposure to heat and UV rays can cause discoloration. Additionally, avoid contact with chemicals or substances that may react with the plastic. Regular cleaning using mild soap and water can also help maintain their original color.

Q:How does groundwater flow into a well pipe? It was a small bore well, made of plastic tubing: The deep well is the filter pipe, and the deep well filter pipe is placed in the underground water layer where the water is to be taken. Some unsuitable water quality underground water layer will not place the filter pipe, so as to avoid using it.

Q:I don't need the candy, just the tubes. Do you know where I can buy them in bulk , and at a reasonable price?: I have no idea, but it is a very specific question... I don't even know what sandy candy is...

Q:i would like like with tubes and levels-like a crittertrail two or three but i've heard about good things and bad things in both...i would like one where it's not impossible to clean and they'll have a blast for the short life that they will have--i don't like caged animals and wish to have something big at least for her to run around--i feel bad for the fact that she's in the little habitrail playground maybe i could add anotherbigger cage--suggestions and personal opinions please....: i'm assuming you are trying to declare which you rather choose to have some hamster tubes working during the cage? Sorry if i'm incorrect yet i might only make a lot of loop-dee-loops from one edge of the cage to the different. The cage is only too small however. he will have a tough time. you will get 10-15 gallon glass fish aquariums and use that for a cage. they are able to be exceedingly low-fee looking on the place you purchase it from. you will get a number of the aquariums and get some aquarium covers at Wal-Mart for around $5.00. The aquarium covers incorporate a around disk you are able to punch out and positioned some tubes in. The bite toys might probley help him from chewing on the tubes, yet your hamster comes to a decision what he desires to bite on and whilst. He probley will bite on the tubes slightly however. in the adventure that your apprehensive approximately him chewing the bars of the cord cage there is one answer that particularly some rodent proprietors, professionals, vets, and breeders have informed me. Get a cotton ball and dip it into some white distilled vinegar. Rub it relatively over the bars and the chewing will end for extra or less half-hour. you ought to maintain re-utilising and that does get annoying even though it works! they do no longer purely like the scent of the vinegar and that they shop away. this would not do them any injury as long as you don't get it of their eyes.

Q:This Saturday I'm going tubing in the Guadalupe River and I'm FREAKING out. I know how to swim but I'm just scared of waterfalls and really rough and tough water. Any information about the rivers currents and the flow will be nice. Also any advise would be greatly appreciated. (The cfs is currently 68 if that is important): EXCELLENT tubing on the Guadalupe River in New Braunfels. Rented hard plastic bottom tubes (once you get to the mini rapids, you'll be glad you got the hard bottom to save your butt from pain) to go down this awesome natural lazy river. Rented the tubes from Rockin R Rivers tubes off of Gruene in New Braunfels. So fun. They pick you up at one of two different spots down the river in a caravan, so you don't have to worry about getting back. You can bring a cooler with non trash items, food, and toys. We had a cooler float, drinks, food, and our beach jai alai game It was just across the river from the bed n breakfast we stayed at. The Gruene Hotel. And right next to the fantastic restaurant Gristmill River Restaurant Bar

Q:Are plastic tubes suitable for hydrostatic testing?: Yes, plastic tubes are suitable for hydrostatic testing.

Q:I recently bought a '95 C220, shes my first MB and after a week of driving I have vowed to never buy any other brand of car. I think i've just about figured out all of her idiosyncricies, however this one still confuses me. There is a small 1/4 diameter or so plastic tube comming out of the floor to the left the battery/fuse box in the trunk, about 8 inches long or so. It has an L connector on the end, but it is not fastened to anything, nor can i find anything that it could fasten to. Any clues anyone? Vaccume tube for some component that was never installed?: i own a repair shop,and its called a battery drain off tube in case the battery spews over or something ,this routes in down toward the bottom of the car instead of letting it stay in the battery tray and eating it up,good luck i hope this help,s.

Q:The dishwasher behind my bar at work has a leak. The pipe that's leaking is Parker Parflex PP 3/8 plastic tubing that connects into a metal nut and brings clean water in. The pipe has a leak exactly where it meets the nut, so in theory I could cut off the cracked portion and then re-seal it to the nut. Can I cut it with wire cutters? Should it be sanded after I cut it? Do I use a teflon sealant? Thanks for any help!: That should be a compression fitting. If it's a brass fitting then they are one time use. You can get a new brass fitting, cut the PP tube clean with a knife or a razor blade - be careful not to cut yourself please, then install the nut over the tube, slip the compression ring over the tube and if there's an insert that goes inside the PP, insert that. Then push the hose into the fitting and slide the nut and ring to the threaded portion of the fitting and tighten it. Be careful to tighten it enough to seal but not so tight you cut through the pipe again. It's likely the reason you have the leak in the first place is because someone overtightened it. OR you can simply buy a replacement hose. I'd prefer a wire braid shielded pipe. Stronger and made with a professional fitting on the end, one you don't have to mess with. My opinion, replacing the tube is the better idea. And they're not stupidly expensive either. Good luck with your project. '')
