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: I want to know if my golden hamster is to big to run through the plastic tubes they give you at the stores because I'm getting him a new cage.: It depends on your perspective. No, I don't know; nevermind.

Q: Regarding NG feeding tubes how difficult is it to take care of someone at home with one? My friend's daughter is coming to stay with me for a little while and her daughter has an eating disorder and is currently being fed with a tube. Her doctor is going to show me how to feed her with it. I was just wondering if this was going to be really complicated or fairly straight forward. Anyone have experience with NG tubes who would like to share their experience using it?: as long as you don't have to replace it, it is easy.

Q: How can a PPC plastic pipe be broken?: Fourth, through the observation that has filled the words of plastic pipe crack, not in the local maintenance, at this time you can either find special tools, or only to find professional aqualux master repair.

Q: how long would it take for air inside a plastic tube 3inch by 1inch to go stale?: What do you mean by go stale? Smell bad? Become contaminated with organics from the tube? I would think you would also need to specify what kind of plastic that makes the tube to have a chance to answer this.

Q: Are plastic tubes suitable for use in the aerospace industry?: Yes, plastic tubes are suitable for use in the aerospace industry. Plastic tubes offer various advantages such as being lightweight, corrosion-resistant, and cost-effective. They are commonly used in applications where weight reduction is crucial, such as fuel and hydraulic systems, ventilation, and electrical wiring. However, the specific choice of plastic material will depend on the specific requirements and conditions of the aerospace application.

Q: I am making a functional balloon water pipe. if at all possible a valve with an electric switch would be ideal so it could be activated from inside a balloon. the tubing will be inside the balloons so they can be pressurized around the tubes. after the tubing is filled with smoke it will be sealed off and the pressure from a balloon will be released forcing the smoke through the tubing inside the pipe. this is what the valve would be used for. a simple ball valve would work, but if there is an electric version small and cheap enough or an alternative im open to suggestions.: Gag, what a dumb concept - balloons break. All kinds of small valves are available for plastic tubing for use in medicine but turning on and off the pump is probably the cheapest. You need surgical rubber tubing to be soft and compressible which is probably going to be damaged by the smoke and how are you going to clean this thing?

Q: I recently bought my house in the dead of winter while there was snow on the ground. The snow has recently melted and revealed that there is about a 6-8 inch plastic tube sticking out of a hole in my lawn. Anyone have any idea of what it is? It is flush with the grass and close to the sidewalk.: If it is closed, with a screw top lid on it, it is the cleanout for the sewer line. Open, it's an intake for a french drain as others have said.

Q: How flexible are plastic tubes?: Plastic tubes can vary in flexibility depending on their composition and thickness. Generally, they are quite flexible and can be easily bent or twisted to fit different shapes and contours. However, their flexibility may be limited in certain applications or if they are made of a more rigid plastic material.

Q: What are the different closure options for squeeze tubes?: There are several closure options available for squeeze tubes, including flip-top caps, screw-on caps, snap caps, and pump dispensers. These closures provide different levels of convenience and functionality, allowing easy access to the product and preventing leakage or spillage.

Q: I have recently upgraded my fishtank. The new one has 3 under-gravel filters and I am using my old charcoal and wool filter as well. I am using a Sonic 9905 pump that has 2 air connections. When I first set it up 2 days ago, all three gravel tubes, connected by T pieces, flowed with no problems and the other filter had it's own tube.Now, either the 2 tubes closest to the pump work, or the further one. They seem to change randomly.How can I get all three to flow constantly?: If the T piece do not have a regulator on it, replace it with one that has. This is usually called an air regulator. It has a knob on it that you can use to regulate the flow of the air in the tube. Or you can buy a piece of valve that can pinch the plastic air tube so that you can regulate the air that goes into one tube or the other. These are available in your LFS. Ask them and let them show you how they do it.
