BET 220–280 m²/g · DBP 300–370 — standard reinforcement for green tires and industrial rubber
SN-CT-199 is a standard white carbon black (precipitated silica) for tire and industrial rubber reinforcement. BET 220–280 m²/g and 300–370 DBP significantly improve tensile/tear strength and abrasion, and it is a key material for green (low-rolling-resistance, low-heat-buildup) tires.
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
