Product introduction
Melamine polyphosphate, called MPOP, is a environmentally friendly halogen free flame retardant containing phosphorus and nitrogen components. It is a new product developed in recent years in our company. It has good expansibility and thermal stability. The processing temperature can be as high as 320 degrees centigrade, small water solubility, low smoke and no moisture absorption.
Melamine polyphosphate MPOP is suitable for glass fiber reinforced nylon 6, nylon 66 and electronic and electrical flame retardant plastics, as well as other engineering plastics.
