Molybdates as a Component of Low Smoke, High Performance Plastics

摘要

Recent results detail the benefits of molybdates, particularly ammonium octamolybdate, in PVC formulations. Low smoke, molybdenum containing, PVC compounds are one of the few materials that can pass the demanding requirements for plenum cables in the U.S. Heat release data will show that molybdenum additives help reduce the heat release in PVC formulations. The mechanism of smoke formation and smoke suppression in PVC will be discussed. Recent process development work has established a new route to an improved grade of ammonium octamolybdate with more consistent properties. Formulations using AOM made by this route give improved thermal stability.
