PVC Dewatering

Cost-Effective PVC Dewatering

Polyvinyl chloride (PVC) is a thermoplastic polymer processed between 320 and 392 degrees Farenheit (160 C and 200 C).

About 34 million metric tons of PVC are manufactured annually worldwide. Important PVC applications include the building industry, the electrical industry and the automotive industry.

Lower Residual Moisture in PVC Dewatering with Decanter Centrifuges

PVC is produced by the polymerization of vinyl chloride monomer (VCM). There are three manufacturing processes:

  • The suspension process
  • The microsuspension process
  • The emulsion process

The manufacture of PVC largely uses the suspension process. Decanter centrifuges are required to dewater the PVC suspension after polymerization. PVC dewatered using Flottweg decanter centrifuges has a lower residual moisture level, which reduces the cost of the subsequent thermal drying process.

Flottweg Decanter Centrifuges Make the Difference Clear

Special Wear Protection

The high forces at work in the centrifuge result in wear on the machine. The wear protection in Flottweg decanter centrifuges reduces wear, and the parts affected can be replaced and renewed.


Product-wetted parts in Flottweg decanter centrifuges are fabricated from high-quality, acid- and rust-resistant stainless steeI, resulting in long service life, the highest possible product quality throughout the process and better stability of the decanter centrifuge.

The Flottweg Simp Drive®

Decanter centrifuges adapt automatically to different load conditions. The Flottweg Simp Drive regulates the differential speed according to the scroll torque, allowing it to dewater the PVC to the maximum total dry solids content.
