UV stabilizers are the key additives for combating material "photoaging," widely used in applications requiring prolonged exposure to sunlight. Through scientific compounding, they can significantly enhance product durability and appearance stability.
Runpacet offers two main types of UV stabilizers to counteract the damaging effects of ultraviolet radiation: UV absorbers, which slow degradation by absorbing UV radiation and dissipating it as heat; and UV inhibitors (UVI), most effective for polyolefins, featuring a broad range of molecular weights and structures suitable for nearly any material application. Unlike absorbers, UV inhibitors do not absorb UV radiation but instead suppress the degradation of polymers by neutralizing already-formed free radicals.
These stabilizers work by absorbing, shielding, or quenching UV energy, preventing oxidative degradation, discoloration, and embrittlement in materials like plastics and coatings caused by UV exposure—thereby extending product lifespan. They can help prolong the service life of multi-season greenhouse films by three years or more.
