Flame Retardant Masterbatch PA-2015FR
PA-205FR is a special halogen-free flame-retardant masterbatch for flame-retardant reinforced nylon . It is a high-efficiency phosphorus-nitrogen flame-retardant masterbatch based on aluminum diethyl hypophosphite (ADP) flame retardant and compounded with phosphorus-nitrogen carbon forming system.
The flame retardant powder is coated with functional group compounds through special chemical reaction surface modification, which improves the processing thermal stability and dispersibility of the flame retardant; at the same time improves the physical and mechanical properties of flame retardant reinforced nylon products, especially It is flame retardant and enhances the moisture and heat aging resistance of nylon products.
The masterbatch of halogen-free flame retardants has enlarged the processing window of halogen-free flame-retardant reinforced nylon, making it easier to produce flame-retardant reinforced nylon products, and at the same time reducing the risk of powder dust.

Precautions for use*
1: Basic formula
(1): In general, in the flame retardant reinforcement system of "nylon + flame retardant masterbatch + glass fiber " , only 0.3% of antioxidant 1098/168 or 1010/168 needs to be added to the formula.
(2): In the flame retardant reinforcement system of " nylon + flame retardant masterbatch + glass fiber " , zinc borate and silicon-based flame retardants can be added.
(3): The addition of olefin tougheners to the formula will affect the flame retardancy and glow wire GWIT value.
2: Processing technology
- : The flame retardant masterbatch can be mixed with all materials such as nylon, and then added at the main feeding port of the twin-screw extruder; the side feeding method is preferred to add the flame retardant masterbatch.
- : The screw speed of the twin-screw extruder should not be too high, so as to avoid the decomposition of the flame retardant caused by high shear heat.
- : The temperature of each heating zone after the extruder adds glass fiber section can be lowered appropriately, it is recommended to set it above the melting point of nylon.
*Specific formula and processing technology issues in production can be discussed and exchanged together.
