Understanding Chemical Compatibility
Chemical compatibility determines whether a substance can be safely stored in a container without causing degradation, contamination, or safety hazards.
HDPE Compatibility Overview
High-Density Polyethylene (HDPE) is resistant to many chemicals but has limitations:
Generally Compatible
- Most acids (dilute and concentrated)
- Alcohols
- Water and aqueous solutions
- Most salts
- Detergents and soaps
- Food products
Limited Compatibility
- Some oils and hydrocarbons
- Strong oxidizers
- Some organic solvents
Not Compatible
- Aromatic solvents (benzene, toluene)
- Chlorinated solvents
- Strong oxidizing acids
- Some ketones and esters
Factors Affecting Compatibility
- Concentration: Dilute solutions often compatible when concentrated is not
- Temperature: Higher temps increase reactivity
- Duration: Long-term storage more demanding than short-term
- Purity: Contaminants may affect compatibility
When to Use Specialty Containers
Stainless Steel IBCs
For solvents, reactive chemicals, and high-purity applications.
Lined IBCs
Special liners for specific chemical families.
Verification Process
- Check manufacturer compatibility charts
- Consult chemical supplier
- Review SDS documentation
- Consider testing when uncertain
