Ultrafine Precipitated Silica

Product Specification

Feature

Ultrafine controlled particle size distribution: Precisely tuned ultrafine primary & secondary particle size, delivers high surface smoothness and excellent filling effect for multiple systems, avoids coarse grit and rough texture in finished products. Large specific surface area & high porosity: Features well‑developed pore structure, brings outstanding adsorption capacity for oil, moisture and active components; works efficiently as carrier, thickener and anti‑caking agent. Excellent dispersibility: Easy to disperse uniformly in rubber, plastics, coatings, adhesives and food‑grade powder systems with low agglomeration, reduces processing energy consumption and improves production efficiency. Superior reinforcing performance: Effective reinforcing filler for rubber and elastomer systems, improves tensile strength, tear resistance and wear resistance, enhances product durability and dimensional stability. Good rheology control effect: Offers ideal thickening, anti‑sagging and thixotropic properties in liquid and paste formulations, prevents sedimentation of solid particles and maintains system stability during storage. High chemical inertness & purity: Low heavy‑metal and soluble impurity content, chemically stable, does not react with most resins, polymers and additives; compatible with diverse formula pH ranges. Excellent matting performance for coatings: Produces uniform matte effect in paint and coating systems, delivers soft surface touch without affecting coating transparency and film‑forming property. Wide‑range application versatility: Suitable for rubber reinforcement, plastic filling, paint matting, adhesive thixotropy, food anti‑caking, cosmetic adsorbent and carrier fields. Stable batch‑to‑batch consistency: Strict process control on precipitation reaction, filtration and drying steps, ensures stable particle size, oil absorption and surface property between batches. Complete compliance documentation: COA, MSDS and relevant regulatory certificates are available, supports customers for product registration, formula development and mass‑production scaling‑up.
