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 make models and the plastic that winds up in the trash could be reused if only I knew how to glue it. I have tried all of mine (401, epoxy, Loctite, Gorilla Glue, etc) to no avail.
- I use E-6000 clear glue for almost everything. I am a sewer and needed some weights so I used this glue on huge metal washers putting two of them together for more weight. I have had these weights for quite a few years. The trick to this glue is to let is set. According to the label is it flexible, paintable, non-flammable, waterproof, safe for photographs, etc. I would suggest not using this in an enclosed area for any length of time. Good luck - Hope that helps.

- Q:Looking for just the top lid, but everyplace only offers the lid, plastic cup and straws.
- off the counter at Mcdonalds
- Q:A plastic tube allows a flow of 12.4 cm3/s ofwater through it.How long will it take to fill a 215 cm3 bottlewith water? Answer in units of s.
- Take 215 cm^3 and divide it by 12.4 cm^3/s, and you'll have your answer. T = (215/12.4) s
