New CRMs for UV Stabilizers
Benzotriazole UV stabilizers are widely used to help protect plastics, coatings, textiles, rubber, and other materials from UV-induced degradation. But as regulatory scrutiny increases, laboratories and manufacturers need reliable reference materials to support method development, identification, quantification, and compliance checks.
AccuStandard has recently expanded its certified reference material range for UV stabilizers, including products relevant to key benzotriazole compounds now attracting global attention.
Why this matters
Recent regulatory activity has increased focus on several benzotriazole UV stabilizers:
- UV-328 was listed under Annex A of the Stockholm Convention in 2023.
- ECHA has identified UV-320, UV-327, and UV-350 as substances with high potential for bioaccumulation and strong resistance to degradation.
- In 2025, ECHA added UV-328, UV-320, UV-326, UV-327, UV-329, and UV-350 to the Candidate List of Substances of Very High Concern.
For Australian customers, this is especially relevant where imported articles, formulations, and finished goods may need to be checked against evolving global restrictions.
