Question:
What are the hazardous products of burning Polyethylene Teraphthalate or PET; high density polyethylene, HPPE; low density polyethylene, LDPE; polyproplene, PP? Also what exactly are Dioxins?


Replies:
Question 2: Dioxins are a class of related chlorinated condensed aromatic cyclic ethers. You can find out a lot, including chemical structure on the web site: http://www.cqs.com/dioxheal.htm

Question 1: All of the polymers you list are hydrocarbons so other than the usual hazards of the combustion of hydrocarbons -- CO2, CO, carbon particles -- there are no unusual hazards.

Additional hazards might be present from components used in the manufacture of plastic parts however. I am thinking of pigments, and other additives.
