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: How are plastic tubes measured?
- Plastic tubes are typically measured by their outer diameter, which is the distance across the widest point of the tube.
- Q: I don't mind cutting the wire but I want to make sure hampster won't get hurt the bubble tube can't be pushed off by her.
- You can fold the wire back so that there are no sharp edges when you cut. You can certainly use zip ties, just check them to make sure your hamster doesnt chew them off. Be creative. Modified cages are fun to make!
- Q: Can plastic tubes be used in medical applications?
- Yes, plastic tubes can be used in medical applications. They are commonly used in various medical procedures such as intravenous therapy, catheterization, and drainage systems.
