Flame Retardant Masterbatch PBT-3025FR
PBT-3025FR flame retardant reinforced nylon non-halogen flame retardant masterbatch is a high-efficiency phosphorus nitrogen flame retardant masterbatch based on aluminum diethyl hypophosphite (ADP) flame retardant 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 the heat and humidity resistance of the product.
The masterbatch of halogen-free flame retardants increases the processing window of halogen-free flame-retardant reinforced PBT, makes it easier to produce flame-retardant reinforced PBT products, and reduces the risk of powder dust at the same time.

Precautions for Use*
1: Basic formula
(1): In general, in the flame retardant reinforcement system of "PBT + flame retardant masterbatch + glass fiber", only 0.3% of antioxidant 1010/168 needs to be added to the formula.
(2): In the flame retardant reinforcement system of "PBT + 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
(1): 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.
(2): 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.
(3): The temperature of each heating zone after the extruder adds glass fiber section can be lowered appropriately, and it is recommended to set it above the melting point of PBT.
*Specific formula and processing technology issues in production can be discussed and exchanged together.
