Cabot has developed a black pigment for polyolefin film applications. BLACK PEARLS® 4040 is Cabot's response to the increasing need for a differentiated product range for film applications.
- Opacity: the extent to which a medium is opaque, i.e. not transparent. The transmission of light through the film is a way to measure the opacity. The higher the amount of transmitted light, the lower the opacity. For more details, see the "Opacity Test for Black Films" brochure
- Weatherability: the UV performance or weatherabilithy is defined as the exposure time in an Atlas Ci65A accelerated weathering chamber required to reach 50% of the initial elongation at break. For more details, see the "UV Weathering and Related Test Methods" brochure
- Film Smoothness: a macroscopic method for assessing the pigment dispersion in a film sample. A film is blown or cast and the number of undispersed pigment agglomerates are visually detected and counted in a specific area
- Dispersability: ease with which the black pigment can be wetted with the resin and subsequently de-agglomerated
