Hexafluoropropylene HFP Monomer Storage — Fluoropolymer Feedstock Tank Selection

Storing Hexafluoropropylene? Start Here

Hexafluoropropylene (HFP) is a colorless gas at room temperature, but it can be stored as a liquid under pressure. It's mainly used in making high-performance fluoropolymers like FEP and Viton. If you're dealing with HFP, understanding how to store it safely is crucial. It’s a reactive chemical that requires specific handling to prevent hazardous situations.

Can you store it in a poly tank?

No, polyethylene tanks are not suitable for storing hexafluoropropylene. This chemical is a pressurized gas and requires storage in pressure-rated vessels like stainless steel or carbon steel cylinders or tube trailers.

Key Issue: Pressure and Reactivity

HFP must be stored under pressure, and it is mildly oxidizing. It can decompose into hazardous products if exposed to high temperatures or electrical arcs. Therefore, using proper pressure-rated equipment and maintaining a controlled environment is essential.

The safety that actually matters

• Use pressure-rated cylinders or trailers for storage.
• Avoid exposure to high temperatures and electrical arcs.
• Ensure all equipment is compatible with HFP to prevent chemical reactions.

Common questions

What materials are safe for HFP storage?

Stainless steel and carbon steel are standard for pressure vessels. PTFE and PFA are suitable for gaskets and seals.

Can HFP be stored at room temperature?

Yes, but it must be under pressure to remain in liquid form.

What are the main uses of HFP?

HFP is primarily used in producing fluoropolymers like FEP and fluoroelastomers like Viton.
