Flame Retardants

Zinc Borate (ZNB-35) ZNB-35 upgrades the thermal stability and UV stabilization of the flame retardant in polymer formulations and acts as a great smoke suppressant by promoting char formation. Thanks to its high dehydration temperature, it is used in production of high temperature resistant polymers. It can be used in both halogen-containing and halogen-free flame retardant formulations. Melamine Cyanurate (MCN) In the last decades, high demands in fire safety have increased the consumption of flame retardant polymers. Not only the reaction to fire, but the reaction to the environment of flame-retarded systems have become key issues. MCN is a halogen-free flame retardant, which meets the requirements of environmental protection and is mainly used for PA6 and PA66 to achieve UL 94 V-0. Above 320°C, it undergoes endothermic decomposition and the vaporized melamine acts as an inert gas source diluting the oxygen and the fuel gases present at the point of combustion. It shows excellent flame retardant properties and compared with APP & MPP, have better compatibility with most carriers. MCN is a colorless, odorless, non-toxic white crystalline powder and it is nearly insoluble in water, and soluble in ethanol, methanol and other organic solvents. Characteristics; Halogen-free, lower smoke density, low smoke toxicity and less corrosion Better electrical and mechanical properties Good thermal stability Environmentally friendly Excellent dispersibility
