MOA3PK-40 (fatty alcohol polyoxyethylene ether phosphate potassium salt) is an anionic specialty surfactant designed for internal static elimination in polymer materials. Its core mechanism lies in forming a continuous ion-conductive molecular layer within the material matrix at low addition levels, significantly reducing the surface resistivity of the product, thereby achieving efficient and long-lasting static dissipation, effectively preventing dust attraction and static accumulation.
With excellent emulsification and wetting properties, MOA3PK-40 can be uniformly dispersed in various polymer substrates and exhibits outstanding chemical stability — resistant to acids, alkalis, and hard water. It has good compatibility with thermoplastics such as PVC, PS, ABS, PE, PP, and polyurethane systems. The processing technique is simple, allowing direct use in internal blending or surface treatment without complex equipment modifications.
| Application Industry | Specific System/Substrate | Typical Process | Functional Effect |
|---|---|---|---|
| Thermoplastic Processing | PVC, PS, ABS, PE, PP | Injection Molding, Extrusion Molding, Blow Molding | Internal blending addition, forming a conductive molecular layer on the product surface, long-term reduction of surface resistance, preventing static accumulation and dust attraction |
| Synthetic Fiber Industry | Polyester, Nylon, Polypropylene, etc. | Melt Spinning, Spin Finish Preparation | Imparting antistatic, smoothing, and bundling properties to fibers, reducing broken filaments and ends, improving weaving efficiency and final product quality |
| Polyurethane (PU) Industry | Flexible/Rigid PU Foam, Cast Elastomers | Foaming, Casting | Reactive or additive antistatic component, achieving long-term static dissipation while maintaining mechanical properties, meeting antistatic requirements for electronic packaging and industrial pads |
| Coatings and Inks | Solvent-based Coatings, Oil-based Ink Systems | Spraying, Roll Coating, Gravure Printing, Screen Printing | Building ion-conductive channels on the coating surface, quickly eliminating static, preventing dust attraction on the film and spark discharge |
As an internal additive antistatic agent, it is recommended to add MOA3PK-40 through blending during plastic processing. The addition amount should be optimized based on the substrate type and target surface resistivity; a low addition amount is usually effective. In spin finish formulations, it can be used in conjunction with other smoothing agents and emulsifiers. For polyurethane systems, compatibility should be confirmed before mixing with polyol or isocyanate components. In coating and ink applications, it is recommended to add during the grinding or dilution stage to ensure uniform dispersion.
