Q1: What is Pigment System FR70 designed for?
A: Pigment System FR70 is a pre-dispersed, solvent-free pigment preparation formulated specifically for high-performance coloration of flame-retardant polymeric systems—particularly halogen-free engineering thermoplastics such as polyamide and polypropylene used in electrical and electronic components.
Q2: Is Pigment System FR70 compatible with common halogen-free flame retardants?
A: Yes, it has been developed and tested for compatibility with major classes of halogen-free flame retardants, including metal hydroxides (e.g., aluminum trihydrate, magnesium hydroxide) and phosphorus-based systems, minimizing adverse interactions such as discoloration or viscosity instability during compounding.
Q3: How is Pigment System FR70 typically incorporated into polymer formulations?
A: It is generally added via masterbatch dilution or direct melt compounding. Due to its optimized dispersion state and thermal stability, it integrates efficiently at typical processing temperatures for engineering thermoplastics without requiring additional dispersing aids or extended residence time.
Q4: Does Pigment System FR70 affect the flame-retardant performance of the final compound?
A: No—when used within recommended dosage ranges, it does not interfere with the flame-inhibiting mechanism of halogen-free systems. Its formulation avoids reactive species that could degrade flame-retardant additives or compromise UL94 V-0 or V-2 ratings in validated formulations.
Q5: What are the key handling and storage recommendations?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and moisture. Avoid freezing. Once opened, minimize exposure to ambient humidity and use within six months for optimal dispersion consistency.
