PPH (Polypropylene Homopolymer) Chemical Storage Tanks are widely used for storing corrosive chemicals due to their excellent resistance to a broad range of acids, alkalis, salts, and industrial process chemicals. Proper chemical compatibility is essential to ensure safe operation, prevent material degradation, and maximize tank service life.

Why Chemical Compatibility Matters

Selecting a chemically compatible tank helps:

  • Prevent corrosion and material degradation
  • Avoid leaks and environmental contamination
  • Maintain chemical purity
  • Extend equipment life
  • Reduce maintenance costs
  • Improve operational safety

Chemicals Commonly Compatible with PPH Tanks

Acids

PPH offers excellent resistance to many inorganic acids, including:

  • Hydrochloric Acid (HCl)
  • Sulfuric Acid (H₂SO₄) – selected concentrations
  • Phosphoric Acid (H₃PO₄)
  • Acetic Acid (dilute concentrations)
  • Citric Acid
  • Formic Acid

PPH is widely used for acid storage in chemical processing and water treatment applications.

Alkalis

PPH demonstrates outstanding resistance to alkaline solutions such as:

  • Sodium Hydroxide (Caustic Soda)
  • Potassium Hydroxide
  • Ammonium Hydroxide
  • Sodium Carbonate Solutions
  • Alkaline Cleaning Solutions

This makes PPH an excellent choice for caustic storage tanks.

Water Treatment Chemicals

PPH tanks are frequently used to store:

  • Sodium Hypochlorite
  • Ferric Chloride
  • Alum
  • Caustic Soda
  • Hydrochloric Acid
  • Polyelectrolytes

Their corrosion resistance and durability make them ideal for water and wastewater treatment facilities.

Chemicals with Good Compatibility

PPH generally performs well with:

  • Dilute mineral acids
  • Organic acids
  • Alkaline solutions
