Ammonium Polyphosphate Phase II (APP II)

 

APP II is completely halogen and formaldehyde-free, non-toxic and does not generate additional smoke. High polymerization degree ("n" value > 1000) of APP II ensures very lower water solubility and and excellent high thermal stability. Based on different industrial applications, Pantech Solutions offers APP II series products aiming at optimal performance and easy applications.
