Melapur 200 is a halogen-free flame retardant. As a white powder it opens up new and broader color schemes for flame retarded glass fiber reinforced PA 66. The mechanism is based on intumescence. At exposure to fire a strong and stable char is formed which protects the polymer and prevents further flame propagation. The good balance between intumescence & thermal stability of Melapur 200 provides a processing window of up to 320 °C.
Melapur MC is a halogen-free flame retardant. Addition levels are relatively low, giving good economics,
mechanical properties and lower specific gravity compared to compounds containing halogen/antimony flame retardant systems. Being halogen free also results in significant advantages in terms of fire safety, i.e. lower smoke density, lower smoke toxicity and less corrosion. Lower corrosivity offers advantages both in the processing stage and in case of a fire. In the processing stage, the lifetime of barrels and molds will be extended, resulting in decreased equipment costs.
Melapur MP is a halogen-free flame retardant. Above ∼ 200 °C melamine phosphate reacts to melamine pyrophosphate, releasing water, which will result in a heat sink effect. Melapur MP is a halogen free FR and offers significant advantages in terms of fire safety, i. e. lower smoke density, lower smoke toxicity and less
