Antistatic agent MOA3PK-70 (also known as alcohol ether phosphate potassium salt) is a functional chemical auxiliary produced by Haian Guoli Chemical Co., Ltd., appearing as a light yellow to yellow transparent liquid. Its core chemical composition is fatty alcohol polyoxyethylene (3) ether phosphate potassium salt, belonging to anionic surfactants. This product, with its excellent antistatic performance and broad resin compatibility, has stable applications in multiple industrial fields.
From the mechanism of action, MOA3PK-70 can form conductive channels within the material, significantly reducing surface resistance even at low addition levels, quickly dissipating static charge accumulation, thereby effectively preventing dust attraction, adhesion, and discharge phenomena caused by static electricity on products. Due to its good internal compatibility with various general-purpose resins such as PE, PP, PS, ABS, and flexible PVC, the antistatic effect is lasting and stable, not easily lost by washing or wiping, which is a significant advantage distinguishing it from common external coating antistatic agents.
In addition to the core antistatic function, MOA3PK-70 also possesses excellent emulsifying and wetting properties. It can serve as a core component in synthetic fiber spinning oil formulations, imparting good cohesion and smoothness to fibers, effectively reducing broken filaments and ends during processing. Meanwhile, this product maintains chemical stability over a wide pH range, has good tolerance to calcium and magnesium ions in hard water, and its liquid form facilitates precise metering and uniform dispersion.
