Product Description
I. Product Introduction
AKnoka® AP400 is a high-polymerization non-halogen phosphorus-nitrogen synergistic intumescent flame retardant that achieves efficient flame retardancy through phosphorus-nitrogen synergy. It exhibits advantages such as low water solubility, high thermal stability, low smoke and toxicity, and excellent compatibility, making it widely applicable to intumescent flame retardant systems and various polymer materials.
II. Product Features
High-temperature carbonization provides oxygen isolation and gas release to suppress combustion, resulting in significantly improved flame retardancy rating. Compatible with high-temperature processing, it exhibits low decomposition tendency, high polymerization with low water solubility, and minimal migration or leaching during prolonged use. The particles are uniformly sized, ensuring stable compatibility with most resins and fillers, along with smooth processing.
III. Application Fields
Engineering plastic systems including household appliance casings, PCB circuit boards, power adapters, and electronic connectors. New energy vehicle applications encompass power battery pack housings, battery insulation pads, battery potting compounds, automotive connectors, and interior materials.
IV. Storage and Packaging
Packaging: Each bag has a net weight of 25 kg and is constructed with a three-layer composite paper bag lined with polyethylene (PE).
Storage: Store in a cool, dry place.
