Strong hydrophobicity & hydrolysis resistance – modified with dimethyldichlorosilane, moisture-proof and hydrolysis-resistant, improve long-term storage stability
Efficient thixotropic thickening – rely on nano-level agglomeration structure to thicken quickly and endow thixotropy, prevent sagging and sedimentation
Excellent reinforcement – as a reinforcing filler for rubber and elastomers, significantly enhance mechanical strength and durability
Powder flow aid & anti-caking – improve powder fluidity, prevent caking, suitable for various powder processing scenarios
High purity & easy processing – ultra-fine particle structure, fluffy without agglomeration, easy to add and compatible with multiple processes
Silicone rubber/elastomers – efficient reinforcement, improve toughness, tear resistance and aging resistance
Paints & coatings – thickening and thixotropy, prevent pigment sedimentation, improve film flatness
Sealants & adhesives – thickening and reinforcement, improve bonding strength, waterproof performance and long-term stability
LED & electronic materials – high purity for encapsulation, ensure insulation and long-term stability of electronic devices
Powder materials – flow aid and anti-caking, adjust charging performance, improve processing and storage convenience
