Product Introduction
Calcined Diatomaceous filler is diatomaceous earth treated through high-temperature calcination, used to enhance the volume, flowability, and fire resistance of materials such as coatings, plastics, and rubber.
Product Advantages
High Purity: Through the selection of high-quality mineral sources and acid-washing purification process, the SiO₂ content reaches ≥85%.
Strong Adsorption: With a specific surface area of 300 m²/g, it can absorb 50% of its own weight in moisture and oil.
Strong Thermal Stability: After ultra-high temperature calcination, it can withstand temperatures up to 900°C.
Production Process
Source factory, high quality, and low price.
Physical & Chemical Properties
Low density, high whiteness, low viscosity, and high purity.
