The benzophenone and benzotriazole based products are termed UV Absorbers and stabilize by 1.) preferential absorbtion of UV light and 2.) dissipating this harmful energy in a safe manner via stabilized excited states. By this mode of action these sophisticated molecules protect plastic products during their useful lifetime.

Specialty additives
ADK STAB LA-31 is a high molecular weight UV absorber belonging to the hydroxy-phenyl benzotriazole family. It protects polymers from UV radiation and extends their exterior lifetime. ADK STAB LA-31 is suitable for the protection of various polymers but especially those demanding low volatility during processing.
Specialty additives
ADK STAB LA-46 provides excellent weatherability for polymers. This product also shows low volatility due to its high thermal stability and good solubility to polymers.
