Fast-Acting Polyolefin Antistatic Agent Nonionic Surfactant Bead, Quick Migration Dust-Proof for LDPE LLDPE PP Film & Injection
**Product Introduction**
This fast‑acting polyolefin antistatic agent is nonionic surfactant supplied in bead form. After melt processing of LDPE, LLDPE and PP, the additive migrates rapidly toward the plastic article surface to build a thin hydrophilic conductive layer. Unlike standard antistatic surfactants that require extended ageing time to reach full antistatic effectiveness, this grade achieves functional antistatic performance within a shorter period. It reduces static‑induced dust attr
Product DetailsThis bead‑form nonionic surfactant possesses amphiphilic molecular architecture with long hydrophobic alkyl chains and multiple hydrophilic hydroxyethyl groups. The optimized molecular chain length enables faster diffusion rate inside the solidified polyolefin matrix. It can be directly dosed during resin mixing or formulated into antistatic masterbatch prior to extrusion, blown‑film and injection‑molding operations for LDPE, LLDPE and PP.
Once the polyolefin melt cools and solidifies, the active surfactant molecules begin migrating outwards quickly to the material surface. Hydrophilic polar groups orient toward the outer surface, absorbing trace atmospheric moisture to form a continuous thin hydrophilic conductive film. This surface layer dissipates static charges immediately, providing dust‑proof antistatic protection without lengthy post‑production ageing storage. This characteristic brings practical production benefits: finished films and injection‑molded articles can be packed right after cooling, shortening warehouse turnaround time.
As a migratory nonionic antistatic additive, its antistatic performance is humidity‑dependent. The static‑dissipating efficiency drops under extremely dry environmental conditions. The fast‑migration property also introduces formulation risks. If over‑dosed, the high diffusion speed will result in heavy blooming, slippery film surfaces, blocking of rolled film reels, and deterioration of downstream printing, lamination and heat‑sealing performance.
Processing temperature should be reasonably controlled during extrusion and injection molding. Excessive barrel temperature may cause surfactant thermal decomposition, generating volatile fumes and reducing antistatic efficacy.
The typical recommended dosage ranges from 0.4 wt%‑1.5 wt% based on total polyolefin resin weight. Pre‑production laboratory testing is required to assess thermal stability during processing, migration speed, surface resistivity, anti‑blocking behaviour of rolled film, heat‑sealing strength and printing adhesion.
Store the bead‑shaped antistatic product in sealed moisture‑proof bags inside cool, dry and ventilated warehouse. Avoid long‑term high‑temperature storage which may induce softening and sticking between beads. Prevent direct sunlight. Reseal packaging immediately after opening to maintain original particle state and processing performance.
