Check before you store, transfer, or respond.
Choose materials with confidence.
Use the One Clarion Chemical Compatibility Tool to quickly confirm whether a chemical is safe with your tank material, hose, pump, gasket, or containment setup, so you can protect crews, avoid costly damage, and document decisions for audits and procurement.
Chemical Compatibility Tool
Search by chemical or material to check compatibility with LDPE, HDPE, and Polypropylene tanks.
Disclaimer: This tool is provided for general reference only. Compatibility ratings are based on published chemical-resistance data for virgin resins at ambient temperatures. Actual performance can vary with concentration, temperature, stress, duration of exposure, and manufacturing variables. Always consult the tank or component manufacturer and review the specific Safety Data Sheet (SDS) before making purchasing or engineering decisions. One Clarion assumes no liability for decisions made using this tool.
Frequently Asked Questions
Get quick clarity on chemical compatibility and material selection. We answer the most common questions about HDPE, LDPE, and PP chemical resistance, including what the ratings mean, what to do when results are “unknown,” and when to confirm with the SDS and manufacturer recommendations.
What is a chemical compatibility chart?
A chemical compatibility chart shows whether a material (like HDPE, LDPE, or polypropylene (PP)) is typically compatible, conditionally compatible, or not compatible with a specific chemical. These charts help evaluate chemical resistance for storage and transfer equipment such as tanks, drums, IBCs, and containment.
What does “Compatible” mean for LDPE, HDPE, or PP containers?
“Compatible” means the material is typically considered suitable for containing that chemical under standard conditions based on published chemical resistance/compatibility data. It is not a guarantee; real-world performance may vary depending on temperature, concentration, mixture components, and storage duration.
What does “Not compatible” mean for plastic chemical storage?
If you’re facing legal issues, from disputes to contracts or criminal charges, consulting a lawyer ensures you understand your rights and options. A quick consultation can help determine if legal representation is necessary.
Is polypropylene (PP) more chemical resistant than HDPE?
It depends on the chemical. Polypropylene chemical resistance is strong for many aqueous solutions, but some solvents or oxidizers may require different materials. The best approach is to compare PP vs HDPE vs LDPE compatibility for your specific chemical and use case.
Do chemical compatibility charts replace engineering review or manufacturer approval?
No. Compatibility charts provide general guidance and are a starting point for selection. For critical applications; especially involving hazardous chemicals, long-term storage, elevated temperatures, or regulatory requirements, confirm with the manufacturer and qualified engineering review.
How do I check if HDPE is compatible with a chemical?
To check HDPE chemical compatibility, search for the chemical by name (or CAS number if available) and review the result for HDPE. Always confirm using the chemical’s SDS (Safety Data Sheet) and the manufacturer’s guidance, since concentration, temperature, and exposure time can change compatibility.
What does “Conditional compatibility” mean?
“Conditional” means the material may work only under certain conditions; such as lower concentration, ambient temperature, shorter contact time, or non-continuous exposure. If you see “Conditional,” verify the details, consult the SDS, and confirm with the container or tank manufacturer before storage.
Why can temperature and concentration change chemical compatibility
Many chemicals become more aggressive at higher temperature or higher concentration, increasing the risk of material degradation or permeation. That’s why chemical compatibility should be evaluated for your expected operating and storage conditions; not just a single “typical” scenario.
Can I use this tool for mixtures, blended products, or formulated chemicals?
Mixtures and formulated products can behave differently than pure chemicals. If you’re storing a blend (for example, a cleaner, fuel mixture, or chemical product), check compatibility for major ingredients and confirm with the product’s SDS and manufacturer recommendations.
What should I do if the tool shows “Unknown”?
“Unknown” means there isn’t reliable published compatibility data in the current dataset for that chemical/material pairing. Do not assume compatibility, use the chemical SDS, consult the container/tank manufacturer, or contact us so we can help identify a safer option.
