What are the advantages of the antistatic agent MOA3PK-70 compared with other similar products?

According to the technical data of Guoli Chemical, the advantages of the antistatic agent MOA3PK-70 over similar products mainly lie in its balanced overall performance, broad compatibility, and excellent process adaptability. It is not only a high-efficiency antistatic agent but also possesses emulsifying, wetting, and stabilizing properties, making it outstanding in demanding polymer material processing and spinning processes.

Detailed Advantage Analysis

1. Efficient and durable antistatic performance with resistance to failure
As an internal additive antistatic agent, it can migrate to the material surface to form a conductive layer, quickly dissipating static electricity, and the effect is long-lasting. Compared with external coating antistatic agents, its antistatic effect will not be lost due to washing or daily wiping. At low addition levels, it can reduce the surface resistivity of plastics to 10^9-10^11 Ω, preventing products from adsorbing dust, sticking to each other, or even discharging due to static electricity.

2. Broad spectrum compatibility with various resins
MOA3PK-70 has good internal compatibility with many common plastics such as PE, PP, PS, ABS, and flexible PVC. This reduces problems such as product exudation, surface whitening, or decreased mechanical properties caused by poor compatibility in formulation design, allowing one product grade to be flexibly applied in different plastic systems.

3. Outstanding emulsifying and wetting functions
This is the core advantage that distinguishes it from many single-function antistatic agents. In synthetic fiber spinning oil agents, it not only provides antistatic protection but also exhibits excellent emulsifying and wetting properties, imparting good cohesion and smoothness to fibers, effectively reducing broken filaments and ends during polyester and nylon spinning processes, achieving multiple functions in one and simplifying the oil agent formulation.

4. Excellent chemical stability
This product remains stable over a wide pH range and has good tolerance to calcium and magnesium ions in hard water. This characteristic ensures that it can continue to function stably in complex water qualities or working fluids with different acidity/alkalinity, without easily producing precipitates or losing effectiveness. This is especially suitable for spinning oil agent systems that require recycling.

5. Good operational processability
The product is a light yellow to yellow transparent liquid with low viscosity and easy flow, making it very convenient for precise metering and uniform dispersion during processing. Whether added to molten resin via an internal mixer or used in preparing oil agents or coatings, it can be quickly mixed, helping to improve production efficiency and product consistency.

Technical Parameter Comparison (Key Indicators)

Compared with other similar phosphate ester antistatic agents, the key indicators of MOA3PK-70 are designed to balance efficacy and safety.

| Technical Indicator | MOA3PK-70 (Guoli Chemical) | Explanation of Technical Advantages |
| :--- | :--- | :--- |
| Active Content (%) | ≥70% | High solid content means high purity and high effective components, enabling more significant antistatic effects at lower cost. |
| Ion Type | Anionic | Compared with cationic antistatic agents, it has less impact on the thermal stability of resins and fewer antagonistic effects with common additives such as heat stabilizers used in plastics. |
| HLB Value | ~4.5 | This HLB value indicates moderate lipophilicity, allowing good compatibility with the resin matrix while possessing certain hydrophilicity for surface moisture absorption and conductivity, balancing internal additive compatibility and surface antistatic effect. |
| Surface Tension (1% / 25℃) | 30-35 mN/m | The low surface tension directly reflects its excellent wetting and penetrating ability, enabling rapid spreading on fiber or resin surfaces to form a uniform conductive layer. |
| Flash Point (℃) | >100 | A high flash point means it is not easily flammable or explosive under normal processing and storage temperatures, making operation safer. |
| pH Value (1% aqueous solution) | 5.0~7.0 | A nearly neutral pH value results in low corrosiveness to substrates and equipment, allowing a wider range of applications. |

Application Suggestions

• In plastic modification: The recommended addition level is 0.5% - 2.0% (based on total resin weight), premixed with resin in a mixer before pelletizing or direct injection molding.
• In spinning oil agents: As one of the core components, the recommended usage is 5% - 20% depending on the oil agent formulation design.
• In coatings and inks: The recommended addition level is 0.2% - 1.0% of the total formulation, added during high-speed dispersion in the paint blending stage.

Precautions

• Its chemical composition is fatty alcohol polyoxyethylene (3) ether phosphate potassium salt (CAS No.: 39322-78-6), which is anionic. Compounding with cationic additives may cause interaction leading to precipitation; compatibility testing should be performed before compounding.
• The product has certain hygroscopicity. After opening the packaging, it should be sealed as soon as possible and stored in a cool, dry place.
