Q1: What types of polymers is Flamestab NOR116 compatible with?
A: Flamestab NOR116 is primarily designed for use in engineering thermoplastics such as polyamide (PA6, PA66), polybutylene terephthalate (PBT), and polyethylene terephthalate (PET), where halogen-free flame retardancy and good thermal stability are required.
Q2: How does Flamestab NOR116 achieve flame retardancy without halogens?
A: It functions through an intumescent mechanism—promoting the formation of a protective, carbon-rich char layer upon exposure to heat or flame, which insulates the underlying polymer and reduces fuel release and heat feedback.
Q3: Does Flamestab NOR116 affect mechanical properties or processing behavior?
A: When properly compounded, it generally maintains good balance between flame performance and mechanical integrity. It exhibits favorable melt flow characteristics and low volatility, supporting stable extrusion and injection molding processes without significant degradation or plate-out issues.
Q4: What is the typical dosage range for effective flame retardancy?
A: Effective loading typically ranges from 0.1% to 2% by weight, depending on the base polymer, desired fire performance level (e.g., UL 94 V-0), and presence of synergists or fillers. Optimization is recommended via lab-scale compounding trials.
Q5: Is Flamestab NOR116 suitable for applications requiring regulatory compliance for food contact or electronics?
A: Flamestab NOR116 is formulated to support compliance with key industry expectations for halogen-free systems, including RoHS and REACH. However, final regulatory acceptance depends on full formulation, processing conditions, and end-use requirements—validation testing is advised for specific applications.
