Uses
Melamine pyrophosphate is an excellent non-halogen chemical useful in various fabrics, nylons, paint, paper and plastics as a flame retardant. It is compatible with melamine-urea formaldehyde systems. It has shown uses in the electronic industry when incorporated in the manufacturing of circuit boards and other equipment. In addition, melamine pyrophosphate can be used with epoxy and other adhesive compositions to achieve fire retardant barriers in gluelines in wood and plastic laminates. Melamine pyrophoshate is useable with di-pentaerythrytol as well as polyolefins. Also useable in SMC process (unsaturated polyester resins). Melamine pyrophosphate can be partially used instead of ammonium polyphosphate (as a spumescent and a catalyst) in some intumescent applications.
Because of the synergism of the combination of the byproducts of melamine pyrophosphate (i.e., phosphorus and nitrogen), only a small quantity is required in formulations. Due to acidic catalysis, inert gas formation and foaming, flames are retarded or eliminated. Melamine pyrophosphate does not contribute to the formation of toxic gases.
Handling
Store in sealed containers at room temperature. Since no exposure limit has been established by OSHA and ACGIH, we recommend that our product be treated as a nuisance dust 15mg/m3. See SDS for more information.
