Century Multech, Inc.
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
