BYK to unveil UV stabilizer for polyamides and polyolefins at K 2025
Last update on Jul 22, 2025
At this year’s K 2025 in Düsseldorf, BYK will be presenting 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 when exposed to light.
Effectively hinders light-induced degradation processes
Polyamide-based components typically deteriorate under prolonged light exposure, affecting both performance and appearance. 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 a great 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. 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.
