Fumed Silica Anti-Blocking Agent is high-purity amorphous fumed silica, CAS 112945-52-5. Produced via high-temperature flame hydrolysis, this fumed silica features ultra-fine primary particle size, large specific surface area and high purity. When incorporated into plastic film formulations, the fine silica particles form micro unevenness on film surface, reducing contact area between stacked film layers to prevent blocking and improve film opening. Besides anti-blocking function, it serves as a

Product Detail

Chemical Identity / TDSProduct Name: Fumed Silica Anti-Blocking Agent CAS No.:112945-52-5 Chemical Type: Fumed Silica, amorphous SiO₂ Physical Form: White fine powder Core Benefit: High purity fumed silica for plastic film, combining anti-blocking opening and matting effect

Key PerformanceThis fumed silica possesses ultra-fine particles and high surface activity. It can produce uniform matte appearance without heavy impact on film mechanical strength. Compared with precipitated silica, fumed silica offers finer particle size and better matting uniformity. The product can be surface-treated (hydrophilic / hydrophobic grade) to fit different resin systems. Particle size, specific surface area and loading dosage refer to manufacturer TDS and formulation trials.

Applications

Matte flexible packaging film modification
Anti-blocking & matting for protective plastic film
Polyolefin film masterbatch additive
PET and multi-layer co-extrusion film formulation
Decorative matte plastic sheet production
R&D of high-performance functional polymer film

ComplianceIndustrial inorganic filler. TDS, MSDS and relevant compliance certificates can be provided for export audit upon request.
