Ammonium Polyphosphate phase II (CM-APP-II)

Application

  • Used to prepare many types of high-efficiency intumescant coatings for the flameproof treatment of multi-story buildings, ships, trains, cables, etc.
  • Used as the main flameproof additive for expanding-type flame retardants used in plastics, resin, rubber, etc.
  • Used in plastics (PP, PE, PVC, etc.), polyester, rubber, expandable fireproof coatings.
  • Flameproof treatment for woods, plywood, fiberboard, papers, and fibers.
  • Can be used for PU applications (thermosets) and PU foam (rigid and/or flexible)

Benefits

  • Halogen and formaldehyde-free, non-toxic and does not generate additional quantities of smoke due to the mechanism of intumescence
  • Requires lower loadings compared to other halogen free systems
  • Exhibits good processability, good retention of mechanical properties and good electrical properties in thermoplastic formulations
  • In thermosets, can be used in conjunction with ATH, which allows a significant reduction of the total FR filler
  • High polymerization degree ("n" value > 1000), higher thermal stability and lower water solubility than APP-I

Packing

  • 25 kg net weight woven plastic / polyethylene bags
  • 17 MT per 20 foot container
