Product Description

Halogen Free Flame Retardant of Phosphorus Nitrogen APP for Rigid PU Foam


Using intumescent ammonium polyphosphate (APP) as flame retardants, the addition of APP into the foam greatly influences the physical-mechanical property. The APP performance indicates it is an effective agent to promote carbon foam formation to produce a cohesive and dense carbon layer, resulting of inhibited the transfering of heat and combustible smoke and increased thermal stability.
