HIFULL HL-150 Hydrophilic Fumed Silica

HIFULL HL-150 is a high-quality domestic hydrophilic fumed silica produced by nano fumed process. It features high purity, large specific surface area, excellent reinforcement, thickening, thixotropy and anti-sedimentation, good dispersibility and compatibility, widely used as high-performance nano silica filler.


Features Of HIFULL HL-150 Hydrophilic Fumed Silica

  1. High-efficiency reinforcement & toughening – significantly improve tensile strength, wear resistance and tear resistance of silicone rubber

  2. Stable rheology & thixotropy – quickly thicken and prevent sagging, improve leveling of coatings and inks

  3. Strong anti-sedimentation – stabilize pigment suspension for a long time, extend storage period

  4. High purity & low impurity – extremely low metal ion content, no impact on transparency and electrical properties

  5. Easy dispersion & processing – fluffy powder, fast wetting and dispersion, compatible with various processes

Typical Applications Of HIFULL HL-150 Hydrophilic Fumed Silica

  1. Silicone rubber products – reinforce HTV/RTV silicone rubber, improve mechanical strength and transparency

  2. Industrial coatings – thicken, thixotropic, anti-sagging, enhance film hardness and scratch resistance

  3. Sealants & adhesives – improve thixotropy and bonding strength, enhance waterproof sealing

  4. Printing inks – stabilize rheology, improve printing clarity and color uniformity

  5. Powder materials – anti-caking and flow aid, optimize processing, packaging and storage
