Antiyellowing Precipitated Silica Silicon Dioxide For Silicone Rubber
Product name: Precipitated silica
Type: SAI - 800
Synonyms: White carbon black, precipitated silica,silicon dioxide,SiO2, hydrated silicon dioxide, hydrated silica
Chemical Properties
Precipitated silica SAI-800 is white powder by selection of raw
materials,with low iron raw materials.It can
be dissolved by NaOH,HF. Other kinds of acid, water and organic
solvents cannot dissolve the
product.
• Cost-effective reinforcing strength
• Outstanding compression-set resistance
• Exceptional resistance to heat-aging
• Excellent tensile-strength, tear-strength and flex-fatigue
resistance
• Reduced crepe hardening
