1. Product Overview
Fiber reinforced polypropylene (FRPP) board is produced by compounding polypropylene with fibers (often glass fibers) and then extruding into flat sheets. The fibers form a reinforcing skeleton inside the PP matrix, increasing the modulus and strength of the material while maintaining much of PP’s corrosion resistance and weldability. As a result, FRPP boards are widely used as structural panels and linings in chemical and environmental equipment.
- Composite design: PP matrix + fibers work together to provide higher stiffness and strength.
- Stable flat sheets: Good flatness and uniform thickness for reliable fabrication and assembly.
- Processability: Can be cut, drilled, machined and welded similar to conventional PP sheets.
2. Key Features
Mechanical & Structural Performance
- High stiffness: Reduced panel deflection under water pressure or wind load compared with standard PP boards.
- Higher strength: Improved load-bearing capability for tank walls, towers, ducts and large equipment shells.
- Better dimensional stability: Less creep and deformation under long-term load and elevated temperature.
Chemical & Environmental Resistance
- Corrosion resistance: Suitable for many inorganic acids, alkalis and salt solutions used in chemical processes and wastewater treatment.
- No rust or scaling: Unlike metals, FRPP does not corrode or introduce metal ions into the medium.
- Low water absorption: Maintains mechanical and dimensional properties in humid or immersed service.
Processing & Fabrication
- Thermoplastic weldability: Can be joined by hot-air welding, extrusion welding or butt welding to build complete equipment.
- Machinability: Standard plastic tools can be used for cutting, drilling, routing and CNC machining.
- Clean, maintainable surface: Smooth surfaces are easy to wipe down and inspect in operation.
3. Typical Applications
- Chemical storage and process tanks: Large rectangular or cylindrical tanks, scrubbers, absorber towers and washing towers.
- Exhaust gas and ventilation systems: Exhaust ducts, flues, elbows, plenums and housings in corrosive or humid conditions.
- Wastewater and environmental equipment: Structural panels and linings for treatment tanks, channels, covers and process units.
- Surface treatment and plating: Etching, pickling and plating tanks, overflow weirs and splash protection components.
- General industrial structures: Load-bearing panels, frames, guards and partitions in chemical or coastal environments.
