BET 120–170 m²/g — low-structure silica for transparent silicone rubber
SN-CT-30 is a precipitated silica developed for silicone rubber, offering stable reinforcement with BET 120–170 m²/g and 260 ml/100g DBP. SiO₂ ≥ 98% and pH ≥ 7 low-ionic grade satisfies both optical clarity and mechanical properties in transparent/semi-transparent silicone products (cables, medical tubing, cases).
Key Features
- 🧱 Synthetic Amorphous SiO₂ — Pure white amorphous powder produced by reacting soluble silicate with acid
- 🧪 High-Purity Management — SiO₂ ≥ 98–99%, with strict control of harmful components such as heavy metals, lead, and arsenic
- ⚙️ Porous Structure — High specific surface area and oil absorption deliver reinforcement, thickening, matting, and adsorption performance
- 🌿 Wide Applications — Applied across industries: rubber, paint, plastics, food/pharma, toothpaste, cosmetics, and more
