PA/PE Masterbatch for Building Wire and THHN Cables – DELTAPLAST
DELTAPLAST PA/PE Masterbatches from Delta Tecnic are specifically designed for the colouring of building wire and THHN cables, where thermal resistance, colour identification and material stability are critical factors.
THHN cables are widely used in electrical installations for buildings and infrastructure, typically incorporating a nylon (PA) layer over PVC insulation to improve mechanical and thermal performance. In these applications, it is essential that colour remains stable during high-temperature extrusion processes.
DELTAPLAST PA masterbatch solutions enable the colouring of the nylon layer while maintaining polymer integrity and ensuring reliable colour identification in electrical installations.

DELTAPLAST PA/PE masterbatches are developed using Nylon 6 as the base polymer, providing excellent thermal resistance and colour stability during processing.
Key features include:
- Solutions tailored for THHN and building wire cables: Masterbatches are specifically formulated for installation wiring applications that include a nylon layer over insulation.
- Stable performance at high extrusion temperatures: Pigments are carefully selected to withstand nylon processing temperatures during extrusion.
- High pigment concentration and excellent opacity: Formulations ensure a fully opaque nylon layer, enabling clear and reliable cable colour identification.
- Consistency across different PA formulations: Masterbatches are designed to perform reliably across various polyamide formulations used in the cable industry.
Additionally, the same colour range is available in PE carrier resin, fully compatible with PA resins, providing greater flexibility in cable formulation.
DELTAPLAST solutions also deliver excellent dilution, colour consistency and solid mechanical performance, ensuring reliable production results.

Technical FAQs
What does THHN mean in electrical cables?
THHN stands for Thermoplastic High Heat-resistant Nylon-coated, a widely used cable type in electrical installations.
Why is nylon used in THHN cables?
The nylon layer provides improved mechanical resistance, abrasion protection and enhanced thermal performance.
What thermal stability do these masterbatches offer?
Pigments can withstand temperatures of up to 300°C, suitable for nylon processing.
Can they be used with PE resins?
Yes. The same colour range is also available in PE carrier resin, compatible with PA formulations.
