Long-term heat ageing
Cable serves for decades at operating temperature, so pigments must resist heat ageing without shade shift that would confuse colour coding.
Applications
Pigments for Cable Compounds
Pigment recommendations for cable compounds with technical checks and export enquiry support.
Cable and wire compounds use organic pigments chiefly for insulation and sheath colour coding, where long service life, heat stability during compounding and freedom from any effect on electrical properties are paramount. Colours must resist heat ageing over the cable's decades of use and, for outdoor cable, weather and UV exposure. Buyers should confirm heat stability through compounding and continuous service, no adverse effect on insulation resistance or the polymer's electrical behaviour, weather fastness for exterior cable, and consistent, distinct shades so colour-coded cores remain identifiable throughout the product's life.
At a glance
What Pigments for Cable Compounds covers
Electrical neutrality
Confirm pigments do not impair insulation resistance or the compound's electrical properties, since colour must never compromise cable safety.
Distinct coding shades
Cores are identified by colour, so pigments must give clean, distinct, reproducible shades that stay unambiguous over the cable's life.
Weatherfast for exterior
Outdoor and buried cable faces UV and weather, so specify weatherfast pigments so sheath colours do not fade or become unreadable.

Answers
Pigments for Cable Compounds — frequently asked questions
Why is heat ageing so important for cable pigments?
Cables operate warm for decades, so pigment must resist long-term heat ageing without shifting shade. A colour that darkens or fades over years could make colour-coded cores hard to identify, creating installation and safety risks. Heat-stable grades keep coding colours accurate throughout the cable's long service life.
Can pigments affect a cable's electrical properties?
They should not, and this must be verified. Pigments and their dispersion carriers must not degrade insulation resistance or other electrical characteristics of the compound. Selection is validated so colour is purely cosmetic and coding-related, never compromising the electrical performance and safety of the insulation or sheath.
How important is colour distinctness in cable cores?
Very important, since installers identify conductors by colour. Pigments must give clean, unambiguous, reproducible shades that stay distinct from each other and do not drift with heat or age. Consistent colour coding across production lots is essential for safe, correct wiring identification in the field.
Do outdoor cables need different pigments?
Yes, exterior and buried cable sheaths face UV and weather, so they need weatherfast pigments that resist fading, whereas indoor cable is less exposed. Faded sheath colour undermines identification and appearance, so outdoor cable compounds specify weather-durable grades matched to the required coding and jacket shades.
