Synthetic Silica Anti-Blocking Agent CAS 7631-86-9, Precipitated Silica for PE PP Film Opening & Slip
Synthetic Silica Anti-Blocking Agent CAS 7631-86-9 is high-performance precipitated synthetic silica, widely used as anti-blocking and slip additive for polyethylene and polypropylene blown films. The irregular silica particles are dispersed uniformly inside the plastic matrix, forming tiny micro-protrusions on the film surface. These micro bumps reduce the contact area between two film layers, effectively eliminating film blocking and making film opening much easier. It also offers moderate sli
Chemical Identity / TDSProduct Name: Synthetic Silica Anti-Blocking Agent CAS No.:7631-86-9 Chemical Type: Precipitated Synthetic Silica / SiO₂ Physical Form: White fine powder Core Benefit: Anti-blocking additive for PE & PP film, improve film opening and slip performance
Key PerformanceThis precipitated silica creates micro roughness on film surface to separate stacked film layers and avoid adhesion. It maintains good transparency of thin films with proper loading dosage. It shows excellent dispersion in polyolefin systems and does not degrade resin mechanical properties. Particle size, pore structure and surface treatment can be customized. Dosage reference, extrusion processing parameters refer to manufacturer TDS.
Applications
- PE blown packaging film anti-blocking modification
- PP cast film opening and slip improvement
- Agricultural plastic film formulation
- Polyolefin film masterbatch additive
- Plastic sheet anti-blocking modification
- Flexible packaging film extrusion production
ComplianceIndustrial inorganic filler. TDS, MSDS and relevant compliance certificates can be provided for export audit upon request.
