Chiguard^® 1033: Superior UV Protection for High-Performance Polymers

Chiguard^® 1033 is an oxalinide-based UV absorber designed to enhance polymer stability and durability. With low initial color, excellent metal ion affinity, and strong antioxidant properties, it provides advanced UV protection while maintaining material clarity and performance.

Key Benefits

• ✅ Preserves material clarity – Low initial color minimizes visual impact
• ✅ Prevents degradation – Strong UV absorption and antioxidant properties enhance longevity
• ✅ Enhances compatibility – Works well with polyamides, PVC, PET/PBT, and styrenic polymers
• ✅ Stable and effective – Maintains performance across various environments

Applications

Chiguard^® 1033 is suitable for protecting polar polymers, providing enhanced UV resistance and stability.

• ✅ Polyamides (PA) – Improves UV stability in engineering plastics
• ✅ Polyvinyl Chloride (PVC) – Reduces yellowing and degradation
• ✅ Polyesters (PET/PBT) – Maintains color and long-term stability
• ✅ Other polymers (PUR, PMMA, Polycarbonates) – Enhances overall durability

Recommended Usage

Chiguard^® 1033 is recommended at a dosage of 0.1%–1.5%, depending on the material type and performance requirements.
