Synthetic Silica Anti‑Blocking Agent is high‑porosity precipitated silica as direct replacement for SIPERNAT 310. Incorporated into polyolefin film masterbatch, it creates micro‑roughness on film surface to prevent blocking. When applied in coating systems, the silica powder offers matting property, improving surface slip for matte coating finished films.

Product Detail

Product Overview Synthetic Silica Anti‑Blocking Agent (CAS 112926‑00‑8, SIPERNAT 310 Equivalent) is highly porous precipitated synthetic silica. For blown and cast polyolefin film production, rigid silica particles form micro‑protrusions on the film surface, reducing contact area between stacked film layers and effectively eliminating film blocking during rolling and unwinding. When dispersed inside solvent‑borne or water‑borne matte coating, the fine silica particles produce uniform matting effect and enhance surface slip property of cured coating film. This synthetic silica is suitable for polyolefin film masterbatch manufacturing as well as industrial matte coating production.

Key Features ‑ Generates micro‑roughness on plastic‑film surface for reliable anti‑blocking performance ‑ Provides consistent matting effect for water‑based and solvent‑based matte coating ‑ Improves surface slip property of both plastic film and cured coating layer ‑ Good thermal stability under polyolefin extrusion processing temperature ‑ Direct functional equivalent grade for SIPERNAT 310 synthetic silica additive

Typical Technical Properties ‑ Chemical Type: Precipitated synthetic amorphous silica ‑ Appearance: White free‑flowing fine powder ‑ Particle Size: Refer to TDS ‑ BET Surface Area: Refer to TDS ‑ Oil Absorption Value: Refer to TDS

Applications ‑ Polyolefin film masterbatch: Anti‑blocking additive for PE and PP blown‑film masterbatch ‑ Flexible packaging film: Slip‑modifying functional silica for cast packaging‑grade film ‑ Industrial matte coating: Matting and slip additive for water‑borne and solvent‑borne coatings ‑ Raw material plant: Functional precipitated silica for plastic and coating compounding

Processing Recommendation For plastic‑film application, incorporate synthetic silica during twin‑screw extrusion to produce anti‑block masterbatch. For coating production, add silica at the grinding‑dispersion stage. Adjust dosage according to targeted anti‑blocking or matting requirement. Complete lab trials prior to mass production.

Storage & Handling Store in cool, dry warehouse and avoid moisture absorption. Reseal packaging immediately after opening. Wear dust‑proof mask and protective gloves when handling fine silica powder.
