Syensqo launches next-generation UV stabilizer to improve value and life-span in rotational molding

New additive CYASORB® CYASTAB™ M5652 offers enhanced durability, safety, and cost efficiency

Syensqo introduces CYASORB® CYASTAB™ M5652 light stabilizer, a breakthrough solution designed to boost durability and appearance in rotomolding applications. This compacted UV stabilizer delivers twice the weathering and color stability of standard options, providing robust UV protection, enhanced safety, and food contact approval. Manufactured at Syensqo’s Zhenjiang plant, CYASORB® CYASTAB™ M5652 strengthens supply reliability and enables a more responsive supply chain for customers across the Asia Pacific region.

CYASORB® CYASTAB™ M5652 is engineered to deliver tangible benefits for both resin producers and rotomolders:

●    Enhanced safety: Its compacted, low-dust, non-sticky granule form improves workplace safety.

●    Simplified handling: The unique form minimizes material loss and simplifies handling during manufacturing.

●    Reliable performance: Built on proven technology and synergistic effects, the formulation ensures reliable performance even under high-temperature processing conditions, helping rotational molding manufacturers optimize system costs.

●    Regulatory compliance: Supports food contact compliance in the U.S. and China, enabling access to regulated applications.

Together, these formulation and processing advantages enable the production of longer-lasting, visually appealing products that better maintain their performance and quality throughout their service life.

“This launch demonstrates Syensqo’s continued investment in advanced stabilization technologies tailored to the evolving needs of the rotomolding industry,” said Stephanie Zhang, Asia Business Director, Polymer Additives. “By combining formulation expertise with regional manufacturing strength, we are committed to helping rotomolders enhance product durability, improve operational performance, and achieve sustainable long-term growth across the APAC market.” 

Looking ahead, Syensqo will continue to expand its portfolio of advanced stabilizers and additives, supporting customers with technical expertise and tailored solutions for evolving industry needs. Syensqo will exhibit at Chinaplas 2026. Come visit and talk to our experts at Hall 7.2, C37.
