>> Quality is our benchmark. It is the only way to give you exactly what you expect for the processing of PVC: a compounding system that achieves highest product quality and maximum operating efficiency.

Processing of PVC

With its Compounding & Extrusion and Materials Handling Competence Centers, Coperion is a specialist for the design and construction of complete plants for the processing of PVC – from the raw material feeding and dryblend production in the heat-cool mixer to the cooling of the pellets.

Our two-stage Kombiplast processing system consisting of a ZSK twin screw extruder and an ES-A single shaft discharge screw forms the heart of these PVC compounding plants. The Kombiplast system achieves highest product quality at maximum throughputs. This is due, among other things, to its excellent mixing properties, its high process flexibility and the optimal compression and venting properties.
