Introduction

This white paper analyzes long-term degradation behavior of PVC and PPCooling tower Fill under industrial conditions.

PVC Performance Characteristics

PVC performs reliably under moderate temperatures.Thermal softening is the primary failure mode.

PP Performance Characteristics

PP exhibits higher thermal resistance and chemical stability,making it suitable for aggressive environments.

Failure Mechanisms Observed in Operation

Deformation, brittleness, and loss of structural integrityare common failure indicators.

Risk-Based Material Selection

Material choice should be linked to operational risk tolerance.
