3. PP (Polypropylene) — lightweight and highly resistant to chemical corrosion.
Preferred for electroplating tanks emitting caustic fumes and alkalis.
- Suitable for a wide range of chemicals.
- Good structural strength for larger hood designs.
4. HDPE (High-Density Polyethylene) — high impact strength and chemical resistance.
Used in environments with moderate chemical exposure and mechanical wear.
- Affordable and versatile.
- Excellent for general-purpose hoods.
5. Stainless Steel (304/316 Grades) — highly durable, with excellent mechanical strength and moderate chemical resistance.
Suitable for high-heat operations or environments where physical impact resistance is required.
- Long service life.
- Can withstand mechanical wear and tear.
- Aesthetic appearance for high-visibility installations.
6. FRP (Fiberglass Reinforced Plastic) — combines chemical resistance with high structural integrity.
Best for highly corrosive environments, especially when handling aggressive acids or solvents.
- Superior corrosion resistance.
- Customizable for complex designs.
- Lightweight but highly durable.
