Antistatic agent MOA3PK-40 (fatty alcohol polyoxyethylene ether phosphate potassium salt), as an anionic specialty surfactant, is designed specifically for static elimination inside polymer materials. Its usage method is highly compatible with common industrial processes such as injection molding, extrusion, spinning, and coating. Since this product belongs to the internal additive type antistatic agent, its core mechanism is to uniformly disperse within the matrix of the product and then migrate to the surface to form a continuous ion-conductive molecular layer, thereby dissipating static charges. Therefore, ensuring molecular-level uniform dispersion of the product in the system is key to achieving the desired effect.
Although this product has excellent chemical stability and compatibility, due to varying compatibility requirements of different substrates (such as PE, ABS, PU, etc.) and different processes (injection molding, calendering, casting, etc.), it is strongly recommended to conduct a small-scale compatibility pre-test before use. This can effectively avoid issues such as surface stickiness, reduced printing fastness, or decreased transparency caused by excessive exudation during mass production.
For different materials and application scenarios, the recommended specific addition methods and process parameters vary. The following table summarizes operational guidelines based on product databases and typical industrial application experience (the addition ratio has no official fixed value and needs to be adjusted according to the target surface resistivity):
| Application Area | Addition Method | Recommended Addition Amount (Empirical Reference) | Key Operational Guidelines |
|---|---|---|---|
| Internal Antistatic for Thermoplastics (PVC, PS, ABS, PE, PP) |
Internal Blending (Melt Mixing) | 0.5% ~ 2.0% (Relative to total resin weight) |
Liquid MOA3PK-40 can be pre-mixed with some plastic particles using a high-speed mixer, or directly injected through a side feed port of a twin-screw extruder. Under the premise of ensuring uniform dispersion, a low addition amount can reduce the surface resistivity to 10⁹~10¹¹Ω, meeting dust-proof and general electronic packaging requirements. |
| Synthetic Fiber Spinning Oil Agent (Polyester, Nylon, Polypropylene) |
Oil Agent Preparation (Aqueous Mixing) | 5.0% ~ 15.0% (Relative to total pure oil agent weight) |
Directly participate in the formulation of spinning oil agent as an antistatic component. Due to its good wetting and bundling properties, it helps form a uniform hydrophilic oil film on the fiber surface, significantly reducing fluffing and yarn breakage during production, and improving weaving efficiency. |
| Polyurethane (PU) Foam and Elastomers | Reactive Addition (Participating in Polymerization) or Blending | 1.0% ~ 4.0% (Relative to total polyol or resin weight) |
For flexible foam, it is usually added to the polyol component and stirred evenly before foaming with isocyanate. Need to check the impact on cell structure after introduction; generally, it does not affect the open-cell rate and mechanical strength of the foam. |
| Oil-Based Coatings and Inks | Surface Treatment (High-Shear Dispersion) | 0.2% ~ 1.0% (Relative to total coating formulation weight) |
Add during the dilution stage of the solvent-based system and disperse using a high-speed disperser for 5-10 minutes. Due to its excellent compatibility, it is not likely to cause loss of gloss or shrinkage cavities in the coating, and can form an ion-conductive channel after the coating cures, eliminating static electricity on the film surface. |
