Polypropylene takes the heat and the chemicals that push polyethylene past its limits, at a fraction of the cost of PVDF.
Choosing a resin
All three resins make good chemical tanks. The right one depends on how hot your chemical runs, what it is and your budget.
Your chemical runs hot, up to 200°F continuous, or it is a strong caustic such as 50% sodium hydroxide or 80% caustic soda, where polypropylene is rated Excellent and HDPE only Good or Fair. It costs more than HDPE but far less than PVDF.
The chemical stays at or below about 120°F and HDPE is rated Excellent for it, as with sodium hypochlorite, ferric chloride or diesel exhaust fluid. HDPE is the most economical tank. HDPE tanks
You store strong oxidizing acids that polypropylene can’t take, such as sulfuric acid above 75%, or need the highest temperature rating. PVDF is the most expensive and is not recommended for strong caustics. PVDF tanks
Temperature and chemicals
Tank ratings from our chemical compatibility database. A = Excellent, B = Good, C = Fair, D = Not recommended.
| Polypropylene | HDPE | PVDF (Kynar®) | |
|---|---|---|---|
| Continuous use temperature | Up to 200°F | About 120°F | Up to 275°F in some uses |
| Relative tank cost | $ | $ | $$ |
| Sodium hydroxide (50%) | A Excellent | B Good | D Not recommended |
| Caustic soda (80%) | A Excellent | C Fair | D Not recommended |
| Potassium hydroxide (50%) | A Excellent | A Excellent | D Not recommended |
| Sulfuric acid (10% to 75%) | A Excellent | A Excellent | A Excellent |
| Hydrofluosilicic acid (20%) | A Excellent | B Good | A Excellent |
| Phosphoric acid (<40%) | A Excellent | A Excellent | B Good |
| Ferric chloride | A Excellent | A Excellent | A Excellent |
| Sodium hypochlorite (<20%) | A Excellent | A Excellent | A Excellent |
| Acetone | A Excellent | B Good | D Not recommended |
Ratings are for the chemical at the listed strength. Temperature changes how any resin performs, so tell us how hot your chemical runs. See all 93 chemicals
FAQ
Our polypropylene tanks are rated for continuous use up to 200°F, compared with about 120°F for HDPE. They are atmospheric tanks, so they must vent freely and never be pressurized.
For hot chemicals and strong caustics, yes. For chemicals HDPE handles well at normal temperatures, HDPE costs less and is the usual choice.
Yes, up to 75%, where it is rated Excellent. From 75% to 93% polypropylene drops to Fair, so use HDPE or PVDF for concentrated acid. See our sulfuric acid tanks.
Yes. Polypropylene is rated Excellent for 50% sodium hydroxide and 80% caustic soda, where HDPE is rated Good and Fair and PVDF is not recommended.
Single wall vertical tanks from 25 to 6,000 gallons, double wall tanks from 100 to 5,000 gallons, plus insulated, cone bottom, open top, horizontal and rectangular styles. See all styles
We install polypropylene fittings at our Willis, Texas plant: welded FNPT couplings, ANSI 150# welded flanges from 1″ to 10″, bulkheads and sanitary tri-clamps, so the tank arrives ready for your piping.
Chemical compatibility
Each chemical page shows how it rates with polypropylene tanks, fittings and gaskets, so you can pick the right EPDM, Viton or Buna-N seal.
