Transparent Film Long-Lasting Conductive Antistatic Agent Fluorinated Ionic Liquid, Low Dosage No Haze for PET PP Transparent Film
This transparent‑film long‑lasting conductive antistatic agent is a fluorinated ionic liquid developed for PET and PP transparent film applications. Different from traditional migratory non‑ionic antistatic surfactants which need relatively high addition levels and tend to cause surface blooming or haze, this fluorinated ionic liquid delivers effective static‑dissipating performance at low dosage. It disperses finely within the film matrix during extrusion and film‑forming. It forms micro‑conduc
Product DetailsThis fluorinated ionic liquid consists of organic cation and fluorine‑containing anionic components. The special fluorinated anion structure improves thermal stability and compatibility with PET and PP resin matrix. It can be incorporated by two feasible processing routes: pre‑compounding into masterbatch for extrusion film production, or liquid feeding for in‑line dosing during film manufacturing.
During melt extrusion and film casting or stretching, the ionic liquid disperses homogenously inside the molten polymer. After the transparent film is cooled and solidified, finely distributed ionic liquid domains form subtle micro‑conductive networks within the film bulk. Static charges generated during unwinding, slitting and high‑speed converting can be dissipated efficiently. Thanks to optimized molecular compatibility, severe outward migration is restrained. Surface blooming and crystal precipitate spots are minimized. At correct working dosage, the film retains high light transmittance and no visible haze, which is essential for transparent‑grade PET and PP film.
This ionic liquid‑based antistatic agent exhibits relatively weak humidity dependence compared with common amine‑based migratory antistatic additives, yet complete humidity‑independent performance cannot be achieved. Under extremely dry conditions, surface resistivity will rise moderately. Over‑dosage will trigger light surface exudation, reduce film gloss, and negatively affect downstream printing, coating and lamination processes. Insufficient dosage fails to build sufficient micro‑conductive networks, resulting in unsatisfactory static‑dissipating results.
Thermal stability is critical for film processing. Although the fluorinated ionic liquid possesses good heat resistance, excessive barrel temperature and prolonged melt residence time should still be avoided. Overheating may trigger partial thermal decomposition, causing tiny dark specks, yellowing and optical defects on transparent film.
The typical recommended dosage ranges from 0.2 wt%‑1.1 wt% based on total polymer weight. Pre‑production laboratory testing must evaluate thermal resistance, dispersion behaviour, film haze and light transmittance, surface resistivity ageing performance, anti‑blooming tendency, as well as downstream printing and lamination adhesion.
Store the transparent film long‑lasting conductive antistatic agent in tightly sealed chemical containers inside cool, dry and ventilated warehouse. Keep away from strong oxidants and direct sunlight. Reseal the container immediately after sampling to prevent moisture ingress and preserve consistent optical‑grade processing performance.
