WebbLight stabilizer (HALS) is to continuously remove the free radicals that are produced by photo-oxidation so the polymers can prolong the service life for long-term use. Plus, the combination of HALS and UV absorber offer synergistic effects to prevent against surface and functional defects. Certification ISO 9001 ISO 14001 ISO 22301 IATF 16949:2016 WebbHindered amine light stabilizers (HALS) are one of two methods of combating UV degradation in polymers. HALS are activated during light exposure by scavenging free radicals created by photooxidation. HALS additives protect the bulk and surface of the polymer depending on the thickness. Hindered amine light stabilizers enhance the …
