Color changes in polyolefin production become possible without interrupting production.
With Coperion’s innovative concept, color changes in polyolefin production are possible from natural to black pellets as well as from black pellets to natural – without cleaning the system. Changeover time from black to color is less than 5 hours.

Coperion focuses not only on CAPEX, but also on Total Installed Costs and OPEX, all while maintaining industry leading process warranty and positively contributing a plant's carbon footprint. Benefit from maximum efficiency in achieving your purpose.
From reactor charging and discharge to additive handling in extrusion processes and logistics, Coperion provides solutions for bulk material handling for all types of plastics. Our scope of equipment and services not only includes pneumatic and hydraulic conveying processes, but also all associated processes such as cooling, heating, discharge (VOC degassing), blending, separating and cleaning.
Material handling technologiesThermal treatment of the product is required in many bulk solids processing systems, which means the product needs to be either heated or cooled. The Coperion Bulk-X-Change® bulk material heat exchanger is a highly-efficient, space and cost-saving device – the ideal solution for thermal treatment of the most bulk materials.
Bulk Solids Heat Exchanger Bulk-X-ChangeThe purity of bulk materials is a decisive factor for the quality of the end product. We focus on minimizing dust generation during the design process for conveying systems. Reduced conveying velocities, suitable pipe materials and connections ensure minimal attrition during production. A varied range of filters and separator concepts are employed to suit the product properties and application requirements.
Filters & SeparatorsFor static homogenization of bulk materials in silos, Coperion offers the FCB Fluid Cone Blender and the CFB Combiflow® Blender. Both units have a homogenization capacity of up to 200 t/h in 1200 m³ silos.

Coperion K-Tron is the premier provider of accurate and reliable feeding equipment for the handling of both resin and additives in polyolefin production processes.
We develop and manufacture key components required throughout the overall process such as single and twin screw feeders, Smart Flow Meters, weigh belt feeders, bag dump stations, a variety of discharge and much more.
FeedersCoperion K-Tron’s Smart Flow Meter (K-SFM) product line provides a reliable and highly accurate means for measuring production rate and adjusting additive feeder setpoints in real time. The K-SFM can be employed in powder/fluff service to measure the rate of base resin into the extruder, or it can be employed in the pellet stream after the classifier to measure total line output. With no moving parts in the product contact areas and an online auto-tare and bypass system, the K-SFM is designed for reliable operation at production rates up to 350 m³/h.
Smart Flow MeterCoperion K-Tron offers a complete range of single and twin screw loss-in-weight feeder configurations for the handling of additives in any form: pellets, premixes/dust-free blends, or powders. We have decades of experience with handling additives with poor flow characteristics at high accuracies. In addition to handling bulk solid additives, Coperion K-Tron offers a line of liquid feeders well-suited for the handling of liquid additives, such as peroxide.
FeedersThe ZSK MEGAcompounder is a closely intermeshing, co-rotating twin screw extruder, providing highest throughput rates and productivity. The modular design of the process section allows various zones to be configured as required for conveying, plasticizing, mixing and shearing, homogenizing, devolatilizing and pressure build-up. The ZSK achieves maximum throughput rates and first-class compound qualities with outstanding process reliability.
ZSK MEGAcompounderWith its large free cross section for devolatilization, the ZS-EG reliably maintains the melt in the process section even at maximum specific torque. Throughput increases and product quality are considerably improved.
Side Devolatilization ZS-EGThe DAV allows for smooth start-up of the equipment, including purging out old, degraded material to the ground. It avoids screens being blocked or contaminated by black specs. The integration of a butterfly valve allows for individual adjustments during operation. Thanks to the DAV, single and two speed machines can be modified according to quality and temperature treatment requirements. The number of operators required for start-up can be reduced and safety can be increased with a DAV. The new, upgraded version of the DAV, the DAV-XT, features some design changes allowing for higher throughputs and providing lower pressure losses. All DAVs can be equipped with a cutting device in order to make handling of purged polymer as easy as possible.
Use of a melt pump is necessary in individual cases for processing and pelletizing polyolefins. It ensures pressure buildup for the melt filtration and pelletizing at a very low introduction of energy. Both Coperion and third-party melt pumps can be integrated into Coperion polyolefin production systems.
Melt Pump MPCoperion’s SWZ screen pack changer is designed specifically for melt filtration in high-performance production systems. The screen packs can be changed during operation without interrupting or reducing production.
Screen Pack Changer SWZCoperion’s UG underwater pelletizer is suitable for pelletizing most thermoplastics. Its optimized flow channels ensure a gentle pressure build-up before pelletizing. It achieves maximum throughput rates thanks to the large number of bores per die plate size.
Underwater Pelletizer UGThe service network of Coperion consists of more than 220 service engineers and technicians around the globe who not only look after your machines and systems but also after your business. They see themselves as partners who secure your future.
