I. Product Introduction

AKnoka® AP440 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 and resistant to decomposition.

High polymerization with low water solubility, exhibits minimal migration and precipitation during prolonged use. Uniform particle size ensures 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.

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.
