Chloride‑Free Sodium Alkane Sulfonate CAS 68037‑49‑0 is an anionic multi‑functional processing additive for thermoplastics including PP, PE and PVC. It combines antistatic, internal lubricating and mold‑release functions in one single product. Elimination of chloride ions prevents corrosion to extruder barrels, screws and mold surfaces during high‑temperature thermoplastic processing. After compounding into resin matrix, active ingredients slowly migrate toward plastic surface to build hydrophil

Product Detail

Product DetailsThis anionic sodium alkane sulfonate features specially purified chloride‑free grade. Conventional sulfonate antistatic grades may contain residual chloride impurities; under high‑temperature shear processing, these chloride residues induce gradual pitting and corrosion on metallic processing equipment. This refined product removes chloride contaminants to mitigate equipment corrosion risk for continuous thermoplastic production.

Its amphiphilic molecular structure contains long‑chain hydrophobic alkane segments and hydrophilic sulfonate‑sodium ionic groups. When incorporated into PP, PE or PVC formulations during compounding, calendering, extrusion or injection molding, it exerts internal lubricating effect, lowering melt friction between polymer molecular chains. It reduces melt viscosity, improves resin fluidity and eases material flow inside extruder and mold cavities, delivering obvious mold‑release benefit for molded parts.

After cooling and solidification of thermoplastic components, active additive molecules gradually migrate to the product surface. Hydrophilic sulfonate groups capture tiny amounts of ambient moisture to form a thin conductive surface film, dissipating static charge accumulation and suppressing dust adhesion on finished plastic products.

Since it belongs to anionic surfactant, direct blending with cationic quaternary‑ammonium additives is forbidden; mixing will trigger flocculation and precipitation, destroying formulation stability. As a migratory antistatic additive, its static‑dissipating performance relies on environmental humidity, and antistatic efficiency decreases under extremely dry conditions. Over‑dosage will cause surface blooming, stickiness and deterioration of surface gloss, printing and hot‑stamping properties of finished thermoplastic parts.

The typical recommended dosage ranges from 0.5 wt%‑1.9 wt% calculated on total thermoplastic formulation weight. Pre‑production laboratory testing is essential to evaluate melt fluidity, thermal stability, surface resistivity, blooming tendency and surface appearance prior to large‑scale production.

Store the product in sealed moisture‑proof packaging inside cool, dry and ventilated warehouse. Avoid prolonged high‑temperature storage. Prevent cross‑contamination with cationic chemical raw materials. Reseal packages immediately after opening to prevent moisture absorption and maintain consistent processing performance.
