Nature
FR-MPP melamine pyrophosphate, also known as melamine pyrophosphate, is a flame retardant containing nitrogen and phosphorus. Its products are white and fine powder. Its outstanding advantages are good thermal stability, insoluble in water, little smoke and no moisture absorption.
The flame retardant principle: MPP has excellent high-temperature processing performance, coke layer generates bubbles in the endothermic decomposition of the cover on the surface of combustion products, plays the role of isolated air, the vaporization of melamine can provide an inert gas source, the concentration of combustible gas and oxygen dilution due to decomposition of polymers produced thereby, flame retardant objective. This product meets the requirements of EU environmental protection directive.


Characteristic
1. no halogen, non-toxic, green environmental products.
2. the thermal stability is good.
3. particles are fine and have good dispersibility.
4. water insoluble, small smoke, no hygroscopic.


purpose
It is widely used in expansive and environment-friendly flame retardants of thermoplastic and thermosetting plastics and silicone rubber and rubber products. It is especially applied to high requirement intumescent flame retardant system and intumescent fireproof coating and acrylic emulsion.

Safety and toxicity
Melamine pyrophosphate (MPP) is a non-toxic flame retardant, but because it is very fine powder, the protection measures are paid attention to in processing.
