AO, UV & Catalyst Additive Masterbatch for Cable Compounds – DELTAPLAST
DELTAPLAST Additive Masterbatches from Delta Tecnic are designed to improve the durability, thermal stability and long-term performance of cable compounds used in demanding industrial and outdoor applications.
Modern cable systems are increasingly exposed to aggressive environmental conditions such as UV radiation, thermal ageing, humidity and oxidation. To ensure reliable performance throughout the cable’s service life, manufacturers require advanced additive systems capable of protecting both the polymer matrix and the final cable structure.
Delta Tecnic develops a complete range of additive masterbatches including UV absorbers, antioxidants (AO), metal deactivators (MD) and catalyst systems, specifically formulated to improve cable stability, simplify compounding processes and optimise production efficiency.
According to the Product Bulletin, these additive solutions help customers comply with increasingly demanding industry regulations while improving outdoor durability and compound processability.

The DELTAPLAST AO/UV/Catalyst/Combo additive systems have been developed to support cable manufacturers and compounders requiring advanced functional protection in PE, EVA and PVC compounds.
Key technical benefits include:
- UV stabilisation for outdoor durability: DELTAPLAST offers UV absorber systems based on HALS (Hindered Amine Light Stabilizers) technology, helping protect cable compounds against degradation caused by prolonged solar exposure. These formulations improve long-term colour stability and preserve mechanical performance in outdoor cable installations.
- Antioxidant systems for thermal stability: Phenolic antioxidant solutions are designed to protect polymer compounds from thermal oxidation during processing and long-term service life. These additive systems contribute to maintaining cable flexibility, insulation performance and mechanical integrity under demanding thermal conditions.
- Metal deactivator (MD) systems: Metal deactivators are used to reduce polymer degradation caused by contact with metallic conductors, helping extend cable lifetime and improve insulation stability.
- Combined additive packages (Combo solutions): Delta Tecnic offers customised additive packages combining several functionalities within a single masterbatch formulation. This approach simplifies the compounding process and improves dosing accuracy while reducing operational complexity.
- Improved processability and production efficiency: The Product Bulletin highlights that DELTAPLAST additive systems help improve processability, simplify production and provide cost-effective solutions for cable manufacturers.
- Compatibility with multiple polymer systems: The additive range is available for several polymer matrices including:
- PE (LLDPE)
- EVA
- ENGAGE™
- PVC
This allows manufacturers to optimise additive incorporation depending on the cable compound technology used.
- Flexible additive concentrations and dosing: The Product Bulletin includes additive concentrations ranging from 5% to 30%, with recommended dosage levels typically between 1% and 5%, depending on the additive system and application.

Technical FAQs
What is an AO additive in cable compounds?
AO stands for antioxidant. These additives help protect polymers against thermal oxidation during processing and service life.
Why are UV stabilisers important in cables?
UV stabilisers protect the polymer from degradation caused by sunlight exposure, helping preserve mechanical properties and colour stability.
What is a metal deactivator (MD)?
A metal deactivator is an additive used to reduce degradation caused by contact between polymers and metallic conductors.
Can multiple additives be combined in one masterbatch?
Yes. Delta Tecnic offers combo additive masterbatches integrating multiple functionalities into a single formulation.
Which polymers are compatible with these additive systems?
The additive range is available for PE, EVA, PVC and ENGAGE™-based compounds.
