Perlite
Perlite is a natural, lightweight, inert, and non-flammable material derived from volcanic rocks. It forms when siliceous lava or ash cools rapidly, allowing water to seep into the rock and become trapped in its glassy structure.

When heated to around 1000°C, perlite expands to approximately twenty times its original volume, creating countless small particles. This expansion process gives perlite its unique physical properties, including very low thermal conductivity and exceptional lightness.

Due to its high permeability, expanded perlite is commonly used for filtering applications such as beverages, edible oils, corn syrups, waste water, and industrial chemicals. Its lightweight and insulating properties also make it an ideal material for insulation and as an additive in construction chemicals.

Perlite filter aids function similarly to diatomaceous earth (DE) filter aids but typically have bulk densities about half that of DE.

With Celafilt® and Celatom® perlite products, AP Mineral provides sustainable solutions for a wide range of industries and applications.
  • Natural and Lightweight: Perlite’s natural structure and light weight make it an essential material in various industries.
  • Inert and Non-Flammable: Chemically inert and fire-resistant, perlite offers safe and reliable usage.
  • Low Thermal Conductivity: Expanded perlite’s low thermal conductivity makes it an excellent insulating material.
  • Versatile Applications: Perlite is widely used in filtration, cosmetics, construction, and gardening.
Perlite Products
Celafilt AP10
Celafilt Perlite products have special permeabilities that provide varying degrees of clarity. While they function similarly to diatomaceous earth (DE), their structural density is about half that of diatomites, making them lighter. Celafilt Perlite products are commonly used for filtering edible oils, starch and glucose products, beverages, waste waters, and industrial chemicals. They are particularly preferred for liquid filtration applications that do not require high levels of clarity.
