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: Are plastic tubes suitable for outdoor applications?: Plastic tubes can be suitable for outdoor applications depending on the specific material and design. Some plastics, such as PVC or HDPE, are UV resistant and can withstand exposure to sunlight and harsh weather conditions. However, it is important to consider factors like temperature, chemical exposure, and mechanical stress when choosing plastic tubes for outdoor use.

Q: I have a long flexible 1 plastic tube that is attached to itself forming a closed circuit and I'd like to add an electric blower to it to flow air continuously that will make a small ball go around continuously. I'd like to splice the blower into the 1 plastic tube but need to know where or how to exhaust the air to keep the air circuit moving continuously in one direction.: The problem is not how to connect the blower, the problem is how to get the small ball to go through the blower (which you can't). What you have to do is to deflect part of the air in the tube to the blower input without allowing the ball to go that path. And then the blower pressurizes the air and injects it downstream of the pick off port. A high pressure low volume blower or pump might be best. That means a small pick off port and a small injection port.

Q: Can plastic tubes be used for automotive applications?: Yes, plastic tubes can be used for automotive applications. They are commonly used for various purposes such as fuel lines, coolant hoses, vacuum lines, and air intake systems. Plastic tubes offer benefits like durability, flexibility, resistance to chemicals and heat, and cost-effectiveness, making them suitable for automotive use.

Q: My 27 lb 4 year old dog possibly ate my Chapstick including the plastic tube. It was pretty small and he has not been acting any differently. My major concern is the plastic part. How soon would I start seeing symptoms if it was causing problems? It's been 24 hours since he ate it. Is something like that passable? Any insight would help! I say he may have eaten it only because I didn't physically see it happen. But one minute it was on the floor and then a minute later all i could find was the cap.: He will either pass it in a day or two. Watch his stools for it. Or if he stops pooping, you will need to take him to the vet because it could be causing a blockage in his intestines. Hopefully, he will just pass it.

Q: What are the common lengths of plastic tubes used for interior design?: The common lengths of plastic tubes used for interior design vary depending on the specific application and project requirements. However, typical lengths range from 1 foot (30 centimeters) to 8 feet (240 centimeters).

Q: How can the PPR pipe be connected with the metal tube?: This is a water storage type electric water heater installation and use of PP-R material, and is connected with the water heater outlet and below the triangle valve components is a special joint installed in the water heater, the components are used to transition metal tube connected with the plastic pipe, the connecting way is to facilitate future maintenance.

Q: does anyone have any ideas on how i can hide my plugs: put a plant in front of it....or you can get a low table. almost like a coffee table that you can put things like picture frames, or DVD player etc. on and that should hide it too

Q: What are the different end types available for plastic tubes?: Some common end types for plastic tubes include open ends, closed ends, threaded ends, flanged ends, and snap-on or twist-on caps. These end types serve different purposes depending on the intended use of the plastic tube.

Q: I just bought a new diehard battery for my 07 nissan versa and taped to the Side was a little L shaped breather tube. I looked and there's a little hole on the side of the battery, where the breather fits. Do I need to use it? What does it do?: i would put it on and direct it down away from anything that the acid could ruin

Q: Are plastic tubes resistant to bending fatigue?: Yes, plastic tubes are generally resistant to bending fatigue due to their flexibility and ability to withstand repeated bending without breaking or becoming damaged.
