摘要：

Waste petroleum refining catalyst from FCC unit was evaluated as a possible component in ammonium polyphosphate (APP) and pentaerythritol (PER) flame-retarding intumescent compositions for polyethylene-based polymers. The use of heating microscopy was introduced as a means of monitoring the intumescence process in situ. By the association of this technique with TG analysis, it was possible to observe that the addition of the waste material to the APP/PER formulations brought about an increase in the residual mass and helped the polymer samples to maintain their structure at temperatures higher than 600 degreesC.
