Decomposition:  Begins to decompose at about 700 degrees Fahrenheit.
Melting Point
:
 Does not melt.
Effects of Acids & Alkalis
:
 Unaffected by most acids, except some strength loss after long exposure to hydrochloric, Sulphuric, and nitric acids. Generally good resistance to alkalis.
Effects of Mildew, Aging, Sunlight & Abrasion
