- Manufacturing of transparent and opaque PVC sheet with thicknesses of 120-300 µm
- Outputs of 1,600 to 2,200 kg/h
- Planetary roller extruder combines good mixing with short residence times
NOX Corporation, Korea, one of the largest producers of luxury vinyl tiles (LVT) worldwide, has recently started operation in a new facility in Fostoria, Ohio, USA. The factory is equipped with several calenders and complete assembly lines. A PWE 250 planetary roller extruder from Battenfeld-Cincinnati Germany is used for the production of top-layer sheet and decorative sheet.

Manufacturing of transparent and opaque PVC sheets with thicknesses of 120-300 µm
The planetary roller extruder, with outputs between 1,600 and 2,200 kg/h, manufactures transparent or opaque PVC sheets with thicknesses of 120-300 µm. The transparent sheet is used as top-layer against scratch marks, while the opaque, mainly white sheet is printed with the decoration. Afterwards, all layers are laminated and embossed together onto a basis material highly-filled with chalk.

LVT: PVC decking laminated from multiple sheet
LVTs are PVC decking laminated from multiple sheet and installed in a similar fashion to laminate flooring. The sheet used is produced with calenders. LVTs have captured a substantial market share in the past years in the area of decking and their share in the segment currently has two-digit growth rates.

Planetary roller extruder combines good mixing with short residence times
The planetary roller extruder system features good mixing properties, short residence times and high surface renewal. Battenfeld-Cincinnati is the only manufacturer that produces all machine components in a grinding process and thus achieves precise geometries as well as high-strength, wear-resistant components.
More than 450 machines in 50 plus countries worldwide
Battenfeld-Cincinnati has been offering planetary roller extruders for many decades, with about 450 machines currently working in the field in more than 50 countries worldwide. Beside the classic machines for PVC sheet production, the company introduced the co-called STARextruder for direct extrusion of PET sheet to the market a couple of years ago. A planetary roller part for degassing the PET melt is an integral component of this extruder.
