HDPE flammability

Flammability? Zip yies? MARV? Ponds? GT specs?
Questions and answers from the GMA Techline.

I am involved with a landfill permit renewal. A question keeps coming up concerning the flammability potential of HDPE liner. What is that potential and do you know of any liner system fires?

HDPE melts between 110 and 140 C. Higher than that, it will burn if oxygen is available. If burning is sustained, the resin and antioxidants will be consumed leaving the carbon black in the form of ash behind. In this regard, it is not unlike all polymers—the differences being at what temperatures the material melts and burns. All organic chemistry books give such information.
