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:Gerbils are chewing on plastic tubes connecting cages. Help!?
No matter what you do, I'm afraid they're not going to quit chewing until they're bored with it. I went through the same deal. What I suggest is take them out and place them in a pin of sorts and place different objects (that you don't mind being chewed on) in the pin with them. Try to get them to find something they like more than that. If not then hell, you tried. It won't hurt them eating the plastic dear so don't worry about that. They don't always eat natural wood anyway they prefer, well, whatever they can get their paws on :) Good day and good luck
Q:Can mercury metal in a thin tube be wrapped around iron to make an electromagnet?
yes and no. copper is 60 times more conductive. that means that mercury wouldn't work nearly as well. in addition, the tube to contain mercury would be much thicker than the insulation around copper. so, while it would work to some degree, it wouldn't work very well.
Q:How do you get a gerbil to climb the plastic tubes in a cage?
Well is the tube just straight up and down? try putting it at an angle that it's not very steep for it. You could stack a few card board boxes or something like stairs if you're really concerned about it not going up. But it knows there's food up there and it will go when it's hungry or thirsty.
Q:What is Dialysis Tubing?
? Ok, its for people with kidney failure to hook them up to dialysis machines which filter blood for impurities. That's pretty generic, but its correct.
Q:Plastic tube how to link three links?
If it is PPR pipe, you can only call outside the master of water and electricity, should be PPR water pipe joints need welding machine, very troublesome.
Q:i had have tubes put in my ears when i was young. Can i still be a military pilot?
Good okorder.com/... Cameron, do not be concerned about your past myringotomy. The plastic tubes were put there to PROTECT your hearing from any damage. The plastic tubes should have fallen out by themselves after a few years? Good luck future military pilot. You and your family have a beautiful day. Peace, from Los Angeles.
Q:when u have laproscopic surgery do they stick a tube down your throat. if so what does it help do.?
Laparoscopic surgery, also called minimally invasive surgery (MIS), bandaid surgery, keyhole surgery, or pinhole surgery is a modern surgical technique in which operations in the abdomen are performed through small incisions (usually 0.5-1.5cm) as compared to larger incisions needed in traditional surgical procedures. .Laparoscopic surgery also referred to as minimally invasive surgery describes the performance of surgical procedures with the assistance of a video camera and several thin instruments. During the surgical procedure, small incisions of up to half an inch are made and plastic tubes called ports are placed through these incisions. The camera and the instruments are then introduced through the ports which allow access to the inside of the patient. The camera transmits an image of the organs inside the abdomen onto a television monitor. The surgeon is not able to see directly into the patient without the traditional large incision. The video camera becomes a surgeon’s eyes in laparoscopy surgery, since the surgeon uses the image from the video camera positioned inside the patient’s body to perform the procedure Benefits of minimally invasive or laparoscopic procedures are less post operative discomfort since the incisions are much smaller quicker recovery times shorter hospital stays earlier return to full activities much smaller scars there may be less internal scarring when the procedures are performed in a minimally invasive fashion compared to standard open surgery. The ET (endotracheal tube) is usually inserted thru your throat into the trachea.which can be hooked up to a ventilator for respirations during surgery.
Q:What's the meaning of the laying of brick and concrete structures with concealed pipes?
The wires are laid in bricks or concrete. If it is concrete, it is buried before pouring and tamping; the brick will be buried after the masonry is finished, and then the slot will be repaired.
