UV Resistance

PA 6 with UV resistance

UV degradation process starts with the absorption of sunlight by the polymer. This energy source can break polymer chains, resulting in a drop in mechanical properties, such as loss of strength, impact resistance and flexibility, and undesirable color changes, including yellowing, loss of gloss and loss of color saturation.

Thanks to its vertical integration from polymerization, NUREL has developed a wide range of UV-resistant polymers by modifying their polymer chains and adding highly effective additives.

From this complete development, the additives incorporated into the polymer matrix are capable of absorbing part of the solar radiation that strikes the polymer, thus preventing this excess energy from breaking the polymer chains.

Polyamide solutions with UV Protection

NUREL’s UV-resistant polymers have a triple protective function, thus providing the highest possible UV protection.

  • First, the additive package absorbs sunlight energy to prevent degradation of the polymer chains.
  • Moreover, the additive package captures free radicals to prevent unwanted effects and endless chain-breaking reactions.
  • Finally, the modification of the polymer chains helps to increase their stability and resistance to solar radiation.


This UV protection system can be applied to the wide variety of polymeric solutions offered by NUREL:

  • When exposed to solar radiation: non-reinforced polymers, polymers reinforced with different percentages and fillers, flame retardant solutions.
  • Outdoor applications where functionality and aesthetics are very important.
