  2. Carbon black - Wikipedia

    en.wikipedia.org/wiki/Carbon_black

    The remaining 10% use of carbon black comes from pigment in inks, coatings, and plastics, as well as being used as a conductive additive in lithium-ion batteries. [5] Carbon black is added to polypropylene because it absorbs ultraviolet radiation, which otherwise causes the material to degrade.

    Carbon black particle size is between 10 and 100 nm, while the surface particle size is between 20 and 1,500 m 2 /g. Generally speaking, small carbon black particles with a high surface area are darker, have higher viscosity and lower wettability, are harder to disperse, retain greater conductivity and absorb UV radiation well.

  7. Laser welding of polymers - Wikipedia

    en.wikipedia.org/wiki/Laser_welding_of_polymers

    Certain color additives, such as titanium dioxide, can have a negative impact on the laser weldability of a polymer. The titanium dioxide provides a white coloring to polymers but also scatters laser energy making it difficult to weld. Another color additive, carbon black, is a very effective energy absorber and is often added to create welds ...
