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 golden hamsters to big to run through the tubes they have at the stores?
It depends on your perspective. No, I don't know; nevermind.
Q:What is the best re-cycling method for plastic bottles & tubes?
Hi The best way is not to buy products that come in plastic bottles, tubes or plastic packaging. Other than that call your local re-cycling center ask them.
Q:water frezze in plastic tube that water goes thru to fill ice maker, so icemaker works fine for a couple fill,
There is a very small heater on the inlet pipe to prevent this. Look in the manual, if you still have it. If you don't, call an appliance parts store with the make and model number of your refrigerator and they give you the right part. If you ask them nicely, they may even give you a diagram showing how to replace the heater yourself. On most refrigerators, it's not a tough job.
Q:in a project tornado with 2 plastic bottles, what can I use instead of a tornado tube?
We always used wide electrical tape. Works fine. [EDIT] MacGuyver was a tv show from the 80s. This guy could do anything with whatever he found lying around. You should totally check it out.
Q:Plastic tube how to link three links?
You can do it yourself. Remember, in the pipe connection, the best combination of the use of fine shar slightly hit point, glue after 12 hours don't try.
Q:How do I cat-proof my grandmother's oxygen tube?
yes go to the local pet store and purchase a nasty tasting spray that dogs and cats cant stand. then just lay it on thick all over the tube!

PUR products are divided into foaming and non foaming products in two major categories of products, foam products are soft, hard PUR foam; non foaming products including paints, adhesives, synthetic leather, elastic and elastic fiber.
Q:What are the water supply plastic pipes or composite pipes?
PE is the most basic plastic of polyethylene plastics, plastic bags, plastic film and so on are PE, HDPE is a high crystallinity, non-polar thermoplastic resin. The appearance of the native HDPE is milky white and is somewhat translucent in the narrow cross section. PE has excellent properties that are resistant to most life and industrial chemicals.
