BYK has introduced an innovative solution for the long-term UV stabilization of polyamides and
polyolefin composites. The new additive was specifically developed to preserve the properties and
surface quality of plastics in the long term when exposed to light, since polyamide-based
components suffer a deterioration of their properties and surface quality when subjected to longer-
lasting exposure to light. Besides deterioration in physical properties, this often also results in
changes in color and gloss. On account of their mechanical strength, temperature resistance and
versatility, polyamides are indispensable in many sectors – from the automotive industry,
construction materials, and consumer and leisure products all the way to fibers and textiles. But UV
radiation can lead to discoloration, loss of gloss, and material degradation.
BYK-MAX LS 4128 addresses this challenge with a synergistic additive of highly concentrated
stabilizers that effectively hinders light-induced degradation processes in the polyamide. In doing so,
the additive acts as a radical catcher and peroxide decomposer, protecting both the visual and the
mechanical properties of the materials, notes a press communiqué from the company. The new BYK
product is a granulated, organic UV stabilization system that was specially developed for use in
polyamides as well as in polyolefins. It is especially well suited for outdoor applications.
A welcome side effect: The high level of active ingredients it contains minimizes the need for carrier
resins, thereby reducing the overall costs for customers. Thanks to BYK’s proprietary technology,
BYK-MAX LS 4128 is a flowable product that is easy to handle.
