Cabot CAB-O-SIL H-5 Hydrophilic Fumed Silica

Cabot CAB-O-SIL H-5 is a hydrophilic fumed silica imported from the US, designed for multi-scenario rheology control and material reinforcement. It can directly replace A300, with high dispersion, strong reinforcement and excellent rheology, widely suitable for silicone rubber, coatings, adhesives, medicine and other fields.

Features Of Cabot CAB-O-SIL H-5 Hydrophilic Fumed Silica

  1. Efficient rheology control - Precisely adjust viscosity and thixotropy of liquid systems, anti-settling and anti-sagging, improve construction stability

  2. Strong material reinforcement - Significantly enhance mechanical strength of silicone rubber, plastics and other materials, improve product mechanical properties

  3. Excellent dispersion and fluidity - Uniform powder dispersion, no caking, improve processing fluency and production efficiency

  4. High purity and stable adaptation - Low impurity content, good batch stability, compatible with various resin systems

  5. Universal replacement advantage - Directly replace A300, high performance matching, reduce formula replacement cost

Typical Applications Of Cabot CAB-O-SIL H-5 Hydrophilic Fumed Silica

  1. Silicone rubber products - Efficient reinforcement, improve tensile strength and wear resistance, extend service life

  2. Coatings and inks - Control rheology and anti-settling, improve coating uniformity and ink printing stability

  3. Adhesives and sealants - Optimize thixotropy and bonding strength, prevent construction sagging, improve sealing effect

  4. Medicine and food - Used as pharmaceutical excipients, improve powder fluidity, ensure preparation processing stability

  5. Unsaturated resins and plastics - Enhance material strength, improve resin transparency and plastic processing performance
