Polyether Polyol Storage — HDPE Bulk Tank Selection

Storing Polyether Polyol? Start Here

If you're handling polyether polyol for your polyurethane manufacturing, you're dealing with a versatile and essential component. This material is typically used in foam and CASE (coatings, adhesives, sealants, elastomers) manufacturing. It's a stable, low-toxicity liquid that doesn't react with polyethylene, making it a good candidate for storage in certain types of tanks. Let's explore your options and considerations for storing polyether polyol effectively.

Can you store it in a poly tank?

Yes, you can store polyether polyol in a polyethylene (HDPE) tank. The chemistry of polyether polyol is non-reactive with polyethylene, and it has a very low vapor pressure, making HDPE tanks suitable for long-term storage. However, if you're dealing with elevated temperatures, consider polypropylene or stainless steel options.

Key Issue: Temperature Sensitivity

While HDPE tanks are suitable for ambient temperature storage, if you need to store polyether polyol at elevated temperatures (110-140°F), you'll need to consider materials like polypropylene or stainless steel to handle the heat without compromising the tank's integrity.

The safety that actually matters

• Ensure tanks are properly ventilated to avoid any pressure build-up.
• Regularly inspect tanks for signs of wear or damage.
• Match gaskets to the manufacturer chart to ensure compatibility.

Common questions

What size tank do I need for polyether polyol?

For most applications, HDPE tanks ranging from 1,000 to 15,000 gallons are standard.

Can I use the same tank for different grades of polyether polyol?

Yes, but ensure the tank is cleaned between uses to maintain product purity, especially for CASE applications.

What kind of gaskets should I use?

EPDM gaskets are standard, but Viton is preferred for blended formulations.
