Effect of Pentaerythritol on the Properties of Wood-Flour/Polypropylene/Ammonium Polyphosphate Composite System

BioResources, 2015
Intumescent, flame-retarding wood-flour/polypropylene composites (WPCs) having different ammonium polyphosphate/pentaerythritol (APP/PER) ratios (4/1, 3/1, and 2/1) were prepared in this study.

Adsorptive Performance of Ni(II) from Aqueous Solutions Using Biochar Made of Phragmites australis by Adding Ammonium Polyphosphate as Flame Retardant

Journal of Chemistry, 2016
The withered Phragmites australis (PA) surrounding the rivers can cause the secondary pollution of water. In this research, by changing the ratio (R) of ammonium polyphosphate (APP), used as flame retardant, to PA at different temperatures, a series of ...

Preparation and Characterization of Microencapsulated Ammonium Polyphosphate with Polyurethane Shell and Its Flame Retardance in Polypropylene

Fire
Polypropylene (PP) shows no charring ability in burning due to the lack of hydroxyl functional groups; thus, the flame retardant system needs an additional amount of carbonizing agent.
