Production process Introduction
Source factory, high quality, and low price.
Industrial Diatomaceous Earth is a highly porous adsorption and filtration material made from natural diatom fossils, widely used in industrial fields such as filtration, adsorption, filling, and insulation.
Advantages
Strong Adsorption Capacity
A microporous structure with a high specific surface area (80-90%) provides rapid adsorption of grease, impurities, or gases.
Stable Filtration Performance
The natural porous structure can trap micron-sized particles, ensuring stable filtration speed.
Good Thermal Insulation and Heat Resistance
The closed-pore structure results in low thermal conductivity and strong heat resistance, making it suitable for use as an insulation material.
Chemically Stable
The main component is SiO₂, which is chemically inert and does not readily react with acids or alkalis.
Product Technical Data Sheet
Low density, high whiteness, low viscosity, and high purity.

FAQ
Q: What is the difference between Industrial Diatomaceous Earth and Food-Grade Diatomaceous Earth?
A: Industrial grade diatomaceous earth is mainly used for non-food applications such as filtration, filling, and adsorption, and its impurity requirements differ. Food-grade diatomaceous earth requires additional safety certification.
Q: What technical parameters are available?
A: Particle size, specific surface area, oil absorption capacity, bulk density, pH, soluble matter, heavy metals, whiteness, etc. Complete TDS (Total Dissolved Solids) can be provided.
Q: Which industries are suitable for?
A: Filtration, oil adsorption, paint filler, rubber and plastic filler, agrochemical carrier, building insulation materials, water treatment, etc.
Q: Has the product undergone safety testing?
A: MSDS, heavy metal testing, soluble matter testing, etc., are available to ensure safety in industrial use.
Q: Can packaging be customized?
A: Custom bag types, ton bags, pallet options, and custom printing are available.
Q: What is the approximate lead time?
A: Regular models are kept in stock and ship in 7-10 days; customized products generally take 15-20 days.
