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 can a PPC plastic pipe be broken?
Secondly, to observe the severity of rupture, if a crack, crack from overflowing. It is simple, can go to the door of the hardware store specially used for repairing plastic pipe rupture glue, be careful not to use any special glue to glue, not professional dyeing water pollution.
Q:What's the diameter of the white plastic tube in the kitchen, about 10cm? What should I do if the water leaks?
PVC-U drain, dn110.PVC drain water leakage, the best and most thorough solution is to replace the damaged part of the pipe. If you do not want to change the tube, you can also use glue glue or welding rod and hot air gun welding.
Q:Where can i get a Tornado tube?
Tornado Tube
Q:Is the white plastic pipe hanging on the outside of the air conditioner broken?
The plastic pipe is discharging the condensed water, long time outside bare weathered, if your air conditioner indoor machines Water Leakage, Flanagan plastic outdoor water pipe flow does not affect the downstairs neighbors if you can not ignore it. The 2 copper tubes are the refrigerant inlet and return pipe. If a large area of leakage in the outside, affecting the cooling effect, it is best to find a maintenance for you to do the next insulation.
Q:Attempting to change the spark plugs in '00 Jeep Grand Cherokee. How do I get the plastic tubes off the plugs?
kind of turn them as you pull no them,they will let go ,but they can be really stubborn to get off,especially if they haven't ever been changed before,don't pull on the wire part its self,it will pull the wire out of the holder and tear the end off of it,keep twisting it and it will eventually get loose,good luck on it.
Q:How do i get a plastic bottle cap out a bottle cup sized hoover tube???????? (some methods already tried)?
Take the tube off the hoover and fit it as tight as you can over an outdoor water spigot. The combination of a bit of lubrication from the water and pressure will sometimes push the obstruction out the way it came in. If that doesn't work you will probably have to find a blunt end stick or rod long enough to force it out. Do not use wire or a straightened clothes hanger. It is too easy to puncture the corrugated hose if it should slip to the side of the cap.
Q:Crazy Glue, why it no stick inside tube? Evaporated Milk, how can the stores sell milk that's evaporated?
The answer to the milk is easy, that is the process that the milk goes through before it is put into the can, FYI Evaporated milk has been around for many generations and was and still used in baking [ask you parents how long a generation is] As for the glue it does not stick to the container because there is no air in the container. Leave the cap off and it will like any other glue get hard.
Q:Plastic Jar, Tubing, PVC?
Peanut butter comes in a container about that size....
Q:C-PAP mask and tubing........smell like plastic......?
At first it will smell but as the other person stated, wash it a few times. The smell will go away. If the mask is leaking, you may not have it adjusted correctly. It could be too loose. Try to tighten the straps a little. Keeping the silicone seal clean helps it have a better seal. If is the air pressure bothering you, dont turn the machine on until you are ready for bed. Try waiting until you are quite tired. Go to bed, turn the machine on, hit the ramp up, put the mask on and go to sleep. By the time the pressure increases, you will be asleep and wont be bothered by it. It does take a little getting used to, but it is well worth the work. If you are still having problems, talk to your dr, that's what they are there for! Remember, people DIE from apnea, if you didnt need the cpap, your dr would not have given it to you. Be proud to be a hosehead!
