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:Connecting icemaker valve to 1/4" tubing?
Are you sure you're putting the fittings together properly. The ferrule (or collar) is tapered and the smaller side should face away from the nut. Also if it's plastic tubing make sure you use a nylon ferrule and not a brass one.
Q:Plastic pipe gas problem 150 degrees, plastic pipe surface problems?
The most widely used plastic pipe is plastic pipe. There are many kinds of plastic pipes, which are divided into two categories: thermoplastic pipes and thermosetting plastic pipes. It belongs to thermoplastic, including PVC pipe, polyethylene pipe, polypropylene pipe, POM pipe, super high molecular weight polyethylene pipe, etc. it belongs to thermosetting phenolic plastic pipe. The main advantages of plastic pipes are good corrosion resistance, light quality, convenient molding and easy processing. The disadvantages are low strength and poor heat resistance.
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:Can mercury metal in a thin tube be wrapped around iron to make an electromagnet?
There's okorder.com/... What this means is the mercury will waste more energy as heat than ordinary wire. What are you trying to build?
Q:What's the full name of "PPC plastic pipe"?
Carbon dioxide copolymers exhibit excellent biocompatibility. The special design of the copolymer can be used as anticoagulant material or used as a drug delivery agent; surface treatment agent of some carbon dioxide copolymer can be used as a solid pigment or filler, the oxygen barrier material, surface active agent, ceramic adhesive, hot melt adhesive; poly propylene carbonate and nitrile rubber blends have good oil resistant heat oxygen aging property, have the mechanical properties than ordinary nitrile rubber better, is a kind of excellent oil resistant rubber.
Q:vacuum cleaner plastic hose and steel extension tube are stuck.?
the cooking oil is a great idea. also sometimes some of them need twisting
Q:My dad on an oxygen machine 24/7, his cat is biting through the plastic tubing at all hours.?
If you cant get rid of the cat just ask your dad to lock it up in a cage or crate when he goes to sleep. Or if the cat does it other times when hes not asleep spray the cat with a water-vinegar solution until it learns.
Q:coin collecting- remove coins, cents stuck in plastic tubes?
whack them with a hammer. I'm not saying whale on it, but a little more than a love tap may jar them loose.
Q:a molten plastic flows out of a tube 8 cm long at a rate of 13 cm^3/min?
Hello Cedric Mapula, let us use the expression V/t = pi P a^4 / 8 l eta Here V/t = volume flown in one sec = 13 cm^3 / 60 s = 13/60 cm^3 /s pi = 3.14 P = 18*13.6*980 a = 1.3/ 20 cm = 0.065 cm l = 8 cm eta = ? Plug these and find the required eta i.e. coefficient of viscosity of liquid Ans : 0.969 g/cm*s = 0.969*10^-3/10^-2 kg/m*s = 0.0969 kg/m*s
Q:What is the name of the plastic tubing that has electrical wiring in it, and is used under concrete?
I assume you're referring to PVC electrical conduit. PVC (polyvinylcholride) is a plastic formulation that is manufactured by the process of extrusion. I hope that helps.
