HIFULL HB-612 Hydrophobic Fumed Silica

HIFULL HB-612 is a high-quality hydrophobic fumed silica prepared by organosilane surface modification. It has high purity, strong thixotropic thickening, anti-sedimentation and excellent reinforcement, with good dispersibility and hydrolysis resistance, designed for polar systems.

Features Of HIFULL HL-380 Hydrophilic Fumed Silica

  1. High specific surface area & activity – stable and controllable surface area, significant thickening and thixotropic effect, excellent anti-sagging performance

  2. Strong reinforcement – as the core reinforcing filler for elastomers, greatly improve product tensile strength, tear strength and wear resistance

  3. Long-term anti-sedimentation – stabilize the suspension state of the system, effectively prevent pigment sedimentation and extend shelf life

  4. High transparency & purity – high silica content, extremely low impurities, no impact on product transparency and electrical properties

  5. Easy dispersion & processing – fluffy powder form, fast wetting and dispersion, suitable for various production processes and reducing processing costs

Typical Applications Of HIFULL HL-380 Hydrophilic Fumed Silica

  1. Silicone rubber/elastomers – efficiently reinforce, improve mechanical properties and structural stability, suitable for high-end rubber scenarios

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

  3. Sealants/adhesives – improve thixotropy and bonding strength, enhance waterproof sealing performance and long-term reliability

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

  5. Unsaturated polyester resin – improve resin transparency, enhance product mechanical properties, suitable for high-end resin products
