Full Description

Diatomaceous earth (CAS 68855-54-9) is a flux-calcined siliceous material composed of fossilized diatom skeletons (amorphous silica). Its high porosity and surface area make it a standard filter aid, and it also serves as a functional filler, mild abrasive, and absorbent.

Frequently Asked Questions

What is Hyflo Super Cel used for?

Hyflo Super Cel is a flux-calcined diatomaceous earth (CAS 68855-54-9) used primarily as a high-flow filter aid for beverages, oils, and process liquids. Its high porosity also makes it useful as a functional filler, mild abrasive, and absorbent.

What is another name for Hyflo Super Cel?

It is diatomaceous earth (DE), also called diatomite or kieselguhr, a siliceous material of fossilized diatom skeletons (amorphous silica). Hyflo Super Cel is a trade name for a flux-calcined grade of this material.

How is Hyflo Super Cel manufactured?

It is produced by mining diatomite, then flux-calcining the milled fossil meal at high temperature with a fluxing agent to develop the coarse, high-permeability particle structure used in filtration.

What HS code applies to Hyflo Super Cel diatomaceous earth?

Diatomite is classified under HS 2512.00 (siliceous fossil meals such as kieselguhr, tripolite, and diatomite, and similar siliceous earths). Confirm the import tariff line with your broker.

What is the price of Hyflo Super Cel and is it available in bulk?

RawSource supplies diatomaceous-earth filter aids in bulk to manufacturers. Pricing varies with grade and quantity, so request a bulk quote with your volume and a CoA/SDS rather than relying on a single list price.
