Overview
PP discs are rigid circular components fabricated from high-density polypropylene via injection molding or compression techniques. These parts exhibit exceptional chemical inertness and structural stability, serving as filtration media, sealing elements, or mechanical spacers in demanding industrial environments.
Application
- Chemical Processing: Used in scrubbers and reaction vessels for gas-liquid separation.
- Water Treatment: Employed in reverse osmosis systems and membrane bioreactors.
- Petrochemical: Functions as packing material in distillation columns and heat exchangers.
Precautions
- Temperature: Continuous service limited to -10°C to +80°C; deformation occurs above 100°C.
- Pressure: Rated for low-pressure applications; avoid sudden pressure shocks exceeding 2 bar.
- Maintenance: Inspect for micro-cracks during thermal cycling; clean with neutral detergents only.
