Wire and Cable Industry

The Wire and cable industry use various types of pigments to color polyolefins. Mainly they are employed for Wire Identification Methods. As in cables, it can be seen the coloring done on the outer layer is governed by a different set of requirements as from the inner layers. Pigments that are used in the wire and cable industries can be of two types inorganic and organic. Newer alternatives that are coming in to the market are known as the "mixed-phase metal oxide" pigments. Examples: yellow nickel Titanates and blue and green cobalt Aluminates. A relatively new entrant is the brilliant yellow bismuth vanadate.
Organic pigments are also used but not as popular because they are more difficult to disperse than inorganic ones leading to possible loss in mechanical strength.

Some common examples are given in this table:

Pigment	Color	Application
Titanium dioxide	White	Used in Variety of resins
Zinc sulphide	White	Wide use
Iron oxides	Red, yellow, brown, and black	Wide use
Lead chromates and lead chromate molybdates	Colors can include bright yellow and orange	Good use
Cadmium	Comes in reds, yellows, oranges and maroons	Excellent for engineering resins
Chromium oxides	Green	Shows good heat and light fastness, variety of uses
Ultramarines	Comes in blue, pink and violet shades	Works in a wide gamut of resins

Factors in Selection of Pigments

There are various factors that govern the choice of colorants when it comes to the Wire and Cable industries:

Humidity
Thermal cycling
Sunlight
Air pollution
Light stability
Resistance to fading
Exposure (Outdoor & Indoor)

Wire Identification Methods
In modern Wire and cable industry, there is a constant need for effective wire identification.
Inkjet Marking- Inkjet technology has vastly improved over the years. With features of less maintenance and faster start-ups, Inkjet marking systems are now more reliable and user friendly. For the wire and cable industry, a dye or pigmented ink, with an Methyl Ethyl Ketone base is applied.
Hot Stamp Marking- Hot stamp marking is still among the most inexpensive techniques for wire identification and is perhaps with exception of laser the only viable option for marking of the Teflon insulated wire. Four important factors here are correct air pressure, dwell time, wheel temperature, and lastly foil. Use of pigments come in the foil part. The foil comprises of a backing and pigment. The pigment gets transferred to wire insulation through the heat emanating from the character wheels. It is vital to note here that certain types of pigments can stick to only particular substrates and would need different temperatures to transfer them.
