Fluorinated ionic liquid antistatic agent based on quaternary ammonium perfluoroalkyl sulfonimide is a special high‑performance antistatic modifier for optical thermoplastic films. Distinct from conventional small‑molecule quaternary ammonium salts which suffer from poor heat resistance and easy thermal decomposition at elevated processing temperature, this fluorinated ionic liquid exhibits outstanding thermal stability. It maintains high transparency without introducing haze or yellowing after

Product Detail

Product DetailsQuaternary ammonium perfluoroalkyl sulfonimide consists of positively charged quaternary ammonium cation and negatively charged perfluoroalkyl sulfonimide anion. The introduction of fluorinated anion structure greatly enhances thermal decomposition temperature and chemical inertness compared with ordinary alkyl quaternary ammonium salt antistatic agents. This ionic liquid additive can be incorporated into resin by masterbatch compounding or solution blending for optical film manufacturing.

When dispersed uniformly within PC, PET or TAC film matrix, the additive forms fine conductive micro‑channels across the film interior. Excess static charges can be dissipated efficiently. It delivers stable antistatic performance without relying heavily on high ambient humidity. The fluorinated molecular design suppresses excessive migration toward the film surface, minimizing the risk of surface blooming, crystal spot formation and contamination on optical film surfaces. It preserves high light transmittance and low haze, which is critical for optical‑grade PC, PET and TAC films used in display‑related applications.

Special attention must be paid to compounding and film‑forming processing conditions. Although the product possesses superior high‑temperature resistance, extreme overheating or prolonged residence time inside the extruder barrel should still be avoided. Excessive thermal load may trigger partial decomposition, leading to tiny dark spots and deterioration of optical performance. For TAC film, solution‑based formulation requires careful control of dissolution speed and filtering procedure to remove any micro‑insoluble impurities.

The recommended dosage range is 0.3 wt%‑1.2 wt% based on total resin weight. The exact loading is adjusted according to target surface resistivity, film thickness and optical specification requirements. Pre‑production laboratory evaluation is mandatory, covering thermal decomposition behaviour, film light transmittance, haze value, surface resistivity, long‑term ageing test and inspection for surface crystal defects.

Store the fluorinated ionic liquid antistatic agent inside tightly sealed containers in cool, dry and ventilated warehouse. Keep away from strong oxidizing agents and direct sunlight. Reseal the container immediately after each use to prevent moisture ingress and maintain original product purity for optical‑grade processing.
