Notes

“Polyethylene (abbreviated PE) or polythene (IUPAC name polyethene or poly(methylene)) is the most common plastic. The annual production is approximately 80 million metric tons.  Its primary use is within packaging (plastic bag, plastic films, geomembranes, etc.).  Many kinds of polyethylene are known, but they almost always have the chemical formula (C2H4)nH2.  Thus PE is usually a mixture of similar organic compound that differ in terms of the value of n.

Polyethylene is a thermoplastic polymer 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 130 °C (248 to 266 °F).  The melting point for average, commercial, low-density polyethylene is typically 105 to 115 °C (221 to 239 °F).

The ingredient or monomer is ethylene (IUPAC name ethene).  It has the formula C2H4, consisting of a pair of CH2 groups connected by a double bond.”

In this day of overworked technical people, keeping up is nearly impossible.  Maro's mission is to help keep up in as little time as possible.  Bookmark this page and check it often.  You will be surprised what can be picked up in just a few moments spent each day.

These pages list the links as they are found.  Some will abstracted and added to Maro Topics. (RDC 2/7/2012)
