Hydrofluoric Acid

What is Hydrofluoric Acid?

Hydrofluoric Acid (HF), otherwise known as Fluoric Acid, is a solution of hydrogen fluoride in water. It’s a colorless liquid with a strong odor.  Hydrogen fluoride easily dissolves in water to form Hydrofluoric Acid solutions, making dilute solutions visibly indistinguishable from water.

What is the most effective storage solution for Hydrofluoric Acid?

Double Wall Plastic Tanks provide the best protection against spills, making it the safest option for Hydrofluoric Acid—one of the most dangerous industrial chemicals.  Additionally, our experts may recommend specific accessories for Hydrofluoric Acid storage, such as proper venting, fittings, joints, manways, and secondary containment.

What is the Specific Gravity of Hydrofluoric Acid?

The specific gravity of Hydrofluoric Acid is 0.98.

Are there special considerations when storing Hydrofluoric Acid?

Hydrofluoric Acid is highly corrosive and should be stored away from incompatible materials, such as metal and glass.

The Assmann Way

The Assmann difference is in the process. Assmann keeps quality first and failure far out of mind.

Uniform Wall Thickness

Uniform wall thickness provides better structural integrity compared to other tanks on the market. Because of its unified durability throughout, Assmann storage solutions are less susceptible to tears and spills, protecting your facility from the corrosive qualities of Hydrofluoric Acid.

Air Cooling

Air cooling eliminates a process related stress in rotomolding, where water cooling shocks the plastic and causes an abrupt stop to the curing process. Assmann is the only manufacturer who uses non-shielded molds with low temperature heat and gradual air cooling to ensure reliability that lasts.

Specific Gravity

Using a 1.9 rated tank gives additional wall thickness to help extend the lifespan of the storage tank. Assmann offers 1.9 rated storage tanks in either crosslink or linear polyethylene. For storing Hydrofluoric Acid, we recommend crosslink polyethylene.


Under-venting is one of the most common causes for tank failure. When filling and draining tanks, it’s important to keep the tank from vacuum and pressure exposure. A vent two times the size of your largest inlet is required to avoid pressurization. Sometimes a larger vent is necessary when tanks are pneumatically filled. Assmann offers a variety of venting options in multiple sizes and configurations.
