Compounding

Our facility for the preparation of mixture controlled by weighing and processes with recipe of NR, IR, BR, SBR, EPDM, CR, NBR, NBR/PVC, ECO, HNBR, VMQ and FKM polymers is based on the following processes:
1. Small scale chemicals weighing (controlled, bar-coded, acclimatized)
2. Closed mixer (tangential armature, automatic carbon-oil loading, duration-heat control)
3. Open mixer mills (with stock blender, duration-heat control, band cutter, barcode reader)
4. Strip mould cooling machine (heat control)
5. Pre-shaping machine - Barwell (with heat-volume control)

BAYKON automatic / controlled weighing system provides weighing and monitoring while IDEA automation system provides the determination of the mixing process.

On each prepared mixture, rheometer, stiffness and density tests are applied. Tensile strength, elongation at break, permanent deformation, micro hardness, friction, the detection of the amount of extracted substances, and aging at air and various liquids are the other tests applied.
