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 got a new syrian hamster two and a half days ago, he has a big wire two storey cage with plastic tubes connecting the upstairs and downstrairs, he's spent mostly all of his time in the tube, taking all the bedding from his little house and his food in it and pooing a lot, I mean the tube is full of poo mixed with food and bedding. (I know this is normal) he's still really shy, he spooks easily, and he's not even been on his wheel yet but he's slowly coming around to me when I hand feed him, I haven't touched him yet though, just leaving him to it for a few days. Should I clean his tubes or is it too early? I don't want to stress him out but I read you are supposed to clean his cage every week and spot clean and clean his toilet area every day and his tubes are his toilet area and I'm seriously not joking when I say he poos a lot.: I think that you should probably clean it out. Do it at night when he is not in the tubes so you do not disturb him. My hamster sleeps in an attachment that goes on the tubes and she does the same thing with the food, pooping, and peeing in there. She loves when I clean it out for her, I do it about every 2-3 days. If I do not clean it out and wait an extra day if I am busy or something she takes all of the bedding out of it and moves it to the regular cage area herself. So yes I do think that you should clean it, he will probably appreciate it!

Q: Can plastic tubes be labeled with product information?: Yes, plastic tubes can be labeled with product information.
