Chemical Resistance
Strong resistance to most acids, alkalis, salts and corrosive organic waste gas in industrial environments.
Chemical Engineering Material
PP board (polypropylene board) is a semi-crystalline material with excellent characteristics such as light weight, non-toxicity, chemical corrosion resistance and good insulation. Its extremely low water absorption and easy weldability make it a practical material for chemical tanks, scrubbers and industrial linings.

Why Choose PP Board
PP board has strong corrosion resistance to most acid, alkali, salt and organic waste gas, and is widely used in chemical processing and wastewater treatment equipment.
Strong resistance to most acids, alkalis, salts and corrosive organic waste gas in industrial environments.
Extremely low water absorption supports dimensional stability in tanks and humid process conditions.
Compared with stainless steel or FRP, PP board offers a practical balance of durability and project cost.
Excellent weldability and processability make it suitable for custom tanks, tower bodies, covers and linings.
Core Applications
PP board is often used to manufacture pickling tanks, electroplating baths, waste gas washing towers, wastewater treatment tanks and tank linings in the chemical industry.

Used for tanks handling acidic pickling solutions where corrosion resistance and low maintenance are required.

Suitable for fabricated baths and auxiliary structures used in metal finishing and electroplating production lines.

Applied in PP spray towers and scrubbing equipment for organic waste gas and corrosive gas treatment.

Reliable for treatment tanks and process containers exposed to wastewater, salts and chemical additives.

Used as lining material to protect industrial tanks from corrosive liquids and extend service life.

Supports integrated gas treatment equipment where lightweight, non-toxic and insulating materials are preferred.
Material Comparison
For many chemical equipment applications, PP board provides a cost-effective and fabrication-friendly alternative.
| Dimension | PP Board | Stainless Steel | FRP |
|---|---|---|---|
| Cost | ✓ Cost-effective | High material and fabrication cost | Moderate, mold dependent |
| Corrosion Resistance | ✓ Strong against most acids, alkalis and salts | Depends on grade and chemical concentration | Good, resin-system dependent |
| Weight | ✓ Lightweight | Heavy | Light to medium |
| Weldability | ✓ Easy thermoplastic welding | Requires metal welding process | Lamination and curing required |
| Maintenance | ✓ Low water absorption and easy repair | Surface corrosion risk in harsh media | Repair quality depends on resin work |
