Precipitated silica powder is a versatile and high-performance additive that can be used in various industrial applications. It is produced by the precipitation of sodium silicate solution with a mineral acid, followed by washing, drying and milling. Precipitated silica powder has several advantages over other types of silica, such as high purity, low moisture content, controlled particle size distribution, high surface area and porosity, and excellent dispersibility.
Some of the specifications of our industrial grade precipitated silica powder are:
- SiO2 content: 98% min
- Moisture content: 5% max
- pH value: 6.0-7.5
- BET surface area: 150-250 m2/g
- Particle size: D50 10-20 μm, D90 40-60 μm
- Oil absorption: 200-300 ml/100g
- Bulk density: 200-300 kg/m3
Our precipitated silica powder can be used for various purposes, such as:
- Reinforcing filler for rubber and plastics
- Anti-caking and free-flowing agent for food, feed and agrochemicals
- Abrasive and polishing agent for toothpaste and dentifrices
- Matting agent and anti-settling agent for paints and coatings
- Carrier and diluent for pesticides and fertilizers
- Thixotropic and rheological modifier for adhesives and sealants
