>> Flexibility and maximum product quality of pellets for the cable industry.
Processing of HFFR
Consistency, reproducibility and product purity are major requirements for the production of high-filled, flame retardant cable materials (HFFR). Continuous processing with Coperion Kombiplast plants completely satisfies these requirements.
The Kombiplast machine from Coperion features a two-stage processing system. This comprises a ZSK twin screw extruder and an ES-A single screw discharge. The systems feature constantly high compounding quality at maximum throughputs. They have been proven for many years in the cable industry and are used for a wide range of applications.
Typical cable compounds which are made in Kombiplast plants
| Halogen-free, self-extinguishing formulations for cables (HFFR) |
| Compounds for low, medium and high-voltage cables on an elastomer basis |
| Cross-linkable PE (mixing of peroxide) |
| Temperature and shear-sensitive products such as PVC insulations and sheaths, XLPE and radiation cross-linkable plastics |
| Semiconductor compounds and special products which contain alloys and blends |
Kombiplast PVC/HFFR hybrid
- Structure of a Kombiplast PVC/HFFR hybrid
The PVC/HFFR hybrid systems are a special version of the Kombiplast. These enable PVC pellets or halogen-free, flame-retardant (HFFR) compounds to be produced economically for the cable industry.
Only a few changes to the Kombiplast PVC/HFFR hybrid are necessary to change products from PVC to HFFR or vice versa. The change can be made within 2 hours depending on the equipment in the plant and the machine size.
