Melt Viscosity Far Higher Than PVC

Fenómeno del problema

Melt flowability is extremely poor during injection and extrusion

Análisis de la causa

High chlorine content leads to stronger intermolecular forces

Solución

Raise processing temperature by 10-15C and enlarge gates and runners

Conclusión clave

CPVC's high viscosity is the biggest processing challenge
