Masterbatches with additives for the Cable Industry

Delta Tecnic, with its extensive experience of more than 30 years, has developed a wide range of Masterbatches with additives for the cable industry with the aim of helping our customers improve the quality and performance of their products. From UV filters, to master combos of additives for HFFR compounds, rodent and termite repellents, anti-dripping agents and biocides, Delta Tecnic’s Masterbatches with additives respond to customer needs for improving processability or cable properties.


Delta Tecnic has developed a range of Masterbatches that incorporate colour and additives for laser marking of the cables. This means the cable is coloured and marked with a single Masterbatch, with the main characteristic colours for this sector currently available.

The cable marking process can be simplified enormously thanks to this Masterbatch range, replacing the inkjet marking and/or hot stamp foil marking.

Laser marking is permanent and resistant to oils and chemical products, providing a very appreciable improvement in the final product.


Delta Tecnic has developed a range of Masterbatches that act as rodent and termite repellents. This solution, an alternative to metal strips or in Polyamide 12, protects the cables from rodent and termite attacks, which can cause short-circuits, fire or losses in cables.

Thanks to micropore sphere technology, Delta Tecnic’s Masterbatches ensure lasting effectiveness.

The range of repellent additives are encapsulated in both EVA (ensuring compatibility with most polymers) and PVC.

Delta Tecnic has studies carried out by highly prestigious European (EU) laboratories such as BAM in Germany and the UB, University of Barcelona, to demonstrate their effectiveness.


Delta Tecnic produces a range of additives incorporating ultraviolet filters, antioxidants or catalysts to improve cable thermal stability and outdoor performance. This range of additives helps the customer exceed the existing demanding regulations in various applications.

Delta Tecnic offers the option of combining the range of additives with the final colour required, providing a final solution in a single Masterbatch. For these cases, we select the pigments with the appropriate lightfastness and thermal resistance to ensure there are no significant colour variations after the tests have been performed.

Demands on mechanical properties, outdoor performance and ease of transformation of the compounds for industry are continually increasing, and this has forced cable manufacturers and compounders in this sector to incorporate a large amount of additives in their formulations. For this reason, we offer an additive combination production service on demand to facilitate incorporation of all the components in a single dose.


Delta Tecnic has developed a Masterbatch range for synergistic action with flame retardants (such as ATH, MDH or ATO) to improve fire resistance properties. The new requirements resulting from the CPR regulations coming into effect has forced cable compound producers, whether manufacturers or compounders, to reduce “heat release”, fume emissions and dripping in cable fire tests.

Our range of Masterbatches, based on sepiolites, help improve these features both in the manufacture of HFFR compounds and in the manufacture of PVC compounds, with better fire performance, helping to reduce fumes and their density.


The cables used in hospitals, operating theatres and clean rooms are subject to increasing demands in terms of their antimicrobial and biocidal properties to ensure a clean environment free from negative effects for the health of professionals and patients.

For this reason, Delta Tecnic has developed a range of Masterbatches using additives with biocidal properties that, incorporated into cable sheathing and insulation, prevent the appearance of microorganisms.
