Sodium Secondary Alkane Sulfonate 93% CAS 68037‑49‑0 is a high‑purity anionic multifunctional processing additive for broad‑range thermoplastic resins. It integrates antistatic and internal lubricating performance. During thermoplastic compounding, extrusion and injection molding, it reduces melt friction to improve resin flow behaviour. After thermal processing, active components slowly migrate toward the finished article surface to build a hydrophilic conductive layer for static dissipation. I

Product Detail

Product DetailsThis 93%‑purity sodium secondary alkane sulfonate is an anionic surfactant‑based thermoplastic additive. Its amphiphilic molecular structure consists of long‑chain hydrophobic secondary alkane hydrocarbon segments and hydrophilic sodium sulfonate ionic groups. The dual‑function characteristic enables it to serve simultaneously as internal lubricant and migratory antistatic modifier within thermoplastic formulations.

At high‑temperature melt‑processing stage, the hydrophobic alkane segments reduce intermolecular friction among polymer chains, lowering overall melt viscosity. It improves melt fluidity during extrusion and injection, alleviates shear heat build‑up inside the barrel, facilitates mold filling and shortens minor mold‑release resistance for molded components. It brings processing benefits for a wide portfolio of resins covering polyolefins, PVC, styrenic resins, engineering plastics and elastomers including PE, PP, PVC, PS, ABS, PC, PET, PA, TPU and EVA.

Once the thermoplastic articles cool and solidify, the additive gradually migrates outward from the polymer bulk toward the material surface. The hydrophilic sulfonate‑sodium groups absorb trace ambient moisture and establish a thin continuous hydrophilic conductive film. This surface conductive layer dissipates accumulated static charges and minimizes dust adsorption on finished plastic parts.

Important formulation constraints must be observed. Being an anionic additive, it cannot be directly blended with cationic quaternary‑ammonium substances; incompatibility will cause flocculation, sedimentation and loss of processing functionality. Its antistatic performance is humidity‑dependent, and static‑dissipating capacity declines when the surrounding environment is extremely dry. Excessive loading will result in surface blooming, surface stickiness, reduced gloss, and impaired printing, hot‑stamping and adhesive bonding properties of finished plastic goods. Certain engineering resins such as PC, PET and PA require stricter pre‑testing for thermal stability to avoid hydrolytic risks during high‑temperature processing.

The typical recommended dosage falls between 0.4 wt%‑1.8 wt% based on total resin formulation weight. Prior to mass production, laboratory trials are mandatory to examine melt flow property, thermal stability, surface resistivity, blooming risk, surface gloss and post‑processing performance for each specific resin system.

Store the product in tightly sealed, moisture‑proof bags inside cool, dry and ventilated warehouse. Avoid long‑term exposure to elevated temperatures. Prevent cross‑contamination with cationic chemical materials. Reseal packaging promptly after opening to stop moisture ingress and preserve consistent product purity.
