In near future, security concerns related to fire-fighting, making environment protection along with promoting adding technology of non-halogen, the demand for high-efficiency of flame-retardant is in target. Melamine pyrophosphate, also known diphosphoric acid, is a flame retardant polypropylene. Melamine pyrophosphate are substances which on combining, the synergistic effect of the melamine pyrophosphate (nitrogen and phosphorus) results in small quantity need in formulations. As of acidic catalysis foaming flame and inert gas formation are eliminated. Melamine pyrophosphate does not contribute to the formation of toxic gases. The formula for the melamine pyrophosphate (MPP) is 2C3H6N6·H4O7P2 and belongs to the certified class of organic materials. Its molecular weight is 304.09. It appearance is fine white powder with no moisture absorption. The salt of melamine pyrophosphate acid is used as halogen free flame retardant and smoke suppressant agent for rubber, paint, paper and other plastics. Melamine pyrophosphate is more compatible with melamine-urea formaldehyde systems. Additionally it is also useable with di-pentaerythrytol, unsaturated polyester resins as well as polyolefins. On the other hand, melamine pyrophosphate can be partly used as an alternative of ammonium polyphosphate in some intumescent (coating, rigid foam, thermoplastics, resins etc) applications.
