PYROLYSIS MODELING OF PVCUSING DISTRIBUTED ACTIVATION ENERGY MODEL-MICRO SCALE TESTING

Polyvinyl chloride (PVC) is a common thermoplastic which finds widespread applications in the construction industry for usage inceiling linings, flooring materials, electrical cables and roofing materials. Several fire requirements are put on these types of applications. For fire safety engineering and product development, thermo-chemical decomposition modeling of PVC isrequired. The FIRETOOLS project investigates the possibilities to predict real scale fire behavior of building products, content and barriers by means of using material data on successively increasing scale. This paper focuses on the material modeling and studies the thermo-chemical decomposition of PVC using Distributed Activation Energy Model (DAEM).
