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.
Efficient rheology control - Precisely adjust viscosity and thixotropy of liquid systems, anti-settling and anti-sagging, improve construction stability
Strong material reinforcement - Significantly enhance mechanical strength of silicone rubber, plastics and other materials, improve product mechanical properties
Excellent dispersion and fluidity - Uniform powder dispersion, no caking, improve processing fluency and production efficiency
High purity and stable adaptation - Low impurity content, good batch stability, compatible with various resin systems
Universal replacement advantage - Directly replace A300, high performance matching, reduce formula replacement cost
Silicone rubber products - Efficient reinforcement, improve tensile strength and wear resistance, extend service life
Coatings and inks - Control rheology and anti-settling, improve coating uniformity and ink printing stability
Adhesives and sealants - Optimize thixotropy and bonding strength, prevent construction sagging, improve sealing effect
Medicine and food - Used as pharmaceutical excipients, improve powder fluidity, ensure preparation processing stability
Unsaturated resins and plastics - Enhance material strength, improve resin transparency and plastic processing performance
