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:the teacher in item 5 needs to order plastic tubing.if each of the 60 students needs 750mm of tubing?
1000 mm = 1m 60*750mm(1m/1000mm) = 45 m best answer?
Q:How to make mice tubes???? :)?
what about plastic vitamin bottles? they are often tube-like? btw, can def show u how to make fun tube hotel out of the core of toilet paper rolls tho... 1. save 3 or more toilet paper roll cores. 2. make some holes on top of the cores so that the mice can climb from one tube to another. 3. get double sided tape (or staple the tubes together if its not sticking) and attach two toilet paper cores together, with the holes on opposite sides of the core so the mice can climb. you can just stack them all together on top of one another and voila! toilet paper core hotels... lol ps. mice loves to chew on things so to grind their teeth to a good length so its perfect for a chew toy too.
Q:How can the pipe support for water supply and drainage be calculated?
The quota regulation is this: the indoor pipe support is all included in the quota, the outdoor pipe support, regardless of the diameter of the pipe, according to the designed pipe support, is calculated by ton.
Q:How can a PPC plastic pipe be broken?
If it is found that the water pipe is broken, and is out of water, splashing water everywhere, then do not panic, to timely close the home tap water valve and turn off the valve, timely cleaning appliances or electrical outlet near the water, to prevent electric shock or cause damage to electrical appliances, and then promptly find repairman repair
Q:where can i buy a small piece of latex tubing?
Jb, Hardware stores have flexible plastic tubing displays of all different diameters of tubing. Would that do?
Q:Is there a safe & secure way to add plastic bubble tubes to a wire hampster cage?
yes use zip ties, they come in all colors and are very strong and nontoxic
Q:Two identical strong magnets are dropped simultaneously into two vertical tubes of the same dimensions?
The magnet from plastic tube would emerge first. This is so because electric emf will be produced in both due to changing magnetic field. But eddy currents will be stronger in copper tube because of free electrons. These currents will apply a retarding force on the moving magnet. In other words copper tube will itself become a stronger electromagnet with a polarity that opposes the motion of the magnet. this effect will be negligible in plastic tube because it has almost no free electrons.
Q:I got a tattoo yesterday n dude used plastic tubes n dnt clean the machine between use...is this ok?
Yay, stirring up some controversy. it extremely is the hip-hop way. Lol only kidding. Umm technically speaking, there's a 2-letter distinction. yet heavily, think of roughly this. A black guy is going as much as his white chum and says, what's up my n*gga?. The white guy responds, Chillin. What you're asserting is that the black guy stated the white guy became right into a n*gger...(and that's faulty) So in a fashion, the be conscious has progressed previous it extremely is slang version of the be conscious n*gger and has now been used as a noun for a individual, regardless of race. there'll constantly be people who do no longer in undemanding terms like the be conscious getting used even though it extremely is been proliferated to the element which you won't have the capacity to do plenty approximately it. And only keep in mind this, i did no longer exchange the which potential of the be conscious, society did. what number songs(extremely rap songs) have used the be conscious?
Q:How to clean the moss in the plastic pipe?
The algae removing agent has the advantages of strong adaptability, wide spectrum of algae removal, simple and convenient use and no pollution. To solve the frequent artificial cleaning, get rid of moss and algae trouble, and ensure the normal and safe operation of the system. Removal of mud, algae and harmful microorganisms from the inner wall of the pipeline equipment; inhibition of circulating water cooling fluid system; propagation of bacteria and algae; unaffected by water quality; strong stability.
Q:Copper tubing 1x 36, threaded on both ends, one end has a plastic ball?
On this description alone, I think it's a valve for a hose. It goes to a connection inside the house and sticks outside the house for the hose. These are built this way so that in winter, the actual mechanism of the ball valve can't freeze.
