FLAMMABILITY OF POLYPROPYLENE BASED COMPOSITE MIXED WITH INORGANIC RETARDANTS
Journal Title: Academic Research International - Year 2013, Vol 4, Issue 3
Abstract
Flammability of polypropylene based composite mixed with zinc borate - antimony pentoxide has been investigated. Retardant layer added on external surface of composite material with (4mm) thick, and tested by thermal erosion test. Antimony pentoxide was added with (10%, 20% and 30%) quantities to zinc borate for enhance the action of this material to react flame. This new retardant was exposed to Oxyacetylene torch flame with (10mm and 15mm) exposure intervals, to study the combustion behavior and resistance of retardant layer to the flame. Thermal erosion test shows that, the large exposed distance and large percentage from protective layer which is zinc borate-(30%) antimony pentoxideis the optimum parameters in flame retarding.
