Our materials

Korrels BV is the specialist in elastomers, engineering polymers, and recycled compounds—delivering both tailor-made solutions and a wide portfolio of standard materials.

4KFLEX

4KFLEX® compounds are developed to customer specifications and produced to order. In addition, we offer a broad range of standard compounds, all with an optimal price-performance ratio and maximum flexibility. Suitable for both injection molding and extrusion applications, available in both large and small quantities.

4KTEC

Our engineering compounds are developed to customer specifications and produced to order. We also offer a wide range of standard engineering polymers available from stock.

Ecompounds

ECOmpounds are high-quality compounds based on recycled materials (PCR and/or PIR) and/or renewable feedstock (bio-based), which we technically upgrade and stabilize to achieve a quality equivalent to prime materials.

Rather than simply reusing recyclates, we apply active upcycling: the material is re-engineered and optimized to ensure it is reliable, reproducible, and suitable for industrial use in serial production.

Renewables

Renewable materials are plastics and compounds produced from renewable or bio-based raw materials instead of fossil resources. These include materials derived from plant-based residual streams or other renewable sources, where fossil components are partially or even fully replaced.
