Black pigment extends service life of plastics

Lanxess has developed a black pigment that reflects 20 % more of the sun’s near-infrared radiation (NIR) than conventional products. Plastic roofs and façade elements that are colored with Bayferrox® 303 T heat up much less due to solar radiation, meaning that the building's inside temperature can be reduced. The temperature in a polymer matrix colored with Bayferrox® 303 T is as much as 8 °C lower than when a conventional black pigment is used. This improves the indoor climate and reduces energy consumption for air conditioning.

IR reflection lengthens service life of black plastics

Using the Bayferrox® 303 T black pigment can also extend the service life of a plastic component considerably as the thermal decomposition of a polymer matrix is reduced due to lower heat absorption. In addition, the difference between daytime and night-time temperatures is much lower. Plastic components are therefore less exposed to thermomechanical stresses that can lead to crack formation or even bursting.

In addition to outdoor applications, Bayferrox® 303 T’s characteristics make it suitable for use in the automotive industry, e.g. to color the dashboard, which is exposed to high and sustained solar radiation. Our pigment makes an effective contribution to reducing heat development in the passenger compartment
