Typical usage ratio

• 0.1%–0.5% w/w relative to the polymer matrix. The dosage is increased in regions with high solar radiation or for lighter colors where photoprotection demands are critical.

Downstream process integration

• Added to the dry blend during compounding, dispersed with heat stabilizers and process aids right before extrusion or injection molding. Monitored by accelerated weathering test panels.

Final product types

• uPVC window and door profiles
• Vinyl exterior siding and cladding
• PVC fencing and railing systems
• Outdoor polymer trims and building elements

3. Industrial Polycarbonate and Polyester Sheets

Producers of translucent polycarbonate and PET sheets use our chemical as a co-stabilizer to prevent yellowing, haze formation, and loss of tensile properties under harsh light exposure. It is fed directly during the melt blending or sheet extrusion phase, enabling product longevity for both indoor and exterior architectural installations.

Industry compliance standards

• EN ISO 4892-2 (Plastics—Methods of exposure to laboratory light sources—Part 2: Xenon-arc lamps)
• ASTM D1925 (Test Method for Yellowness Index of Plastics)
• REACH Annex XVII for restricted substances
• RoHS compliance for electrical accessory housing

Typical usage ratio

• 0.15%–0.6% w/w in polycarbonate and copolyester blends, with higher levels in thinner gauges or optical grades to ensure low delta-E shift over service life.

Downstream process integration

• Metered into extruder feed hoppers alongside resin, pigments, and co-stabilizers, ensuring thorough mixing in the melt phase prior to die forming or calendering.

Final product types

• Solid and multiwall polycarbonate architectural glazing panels
• PET roofing sheets
• Protective machine guards and canopies
• Industrial skylight covers

4. Synthetic Turf & Outdoor Textile Fibers

Manufacturers of artificial grass and performance outdoor fabrics apply this UV stabilizer in their fiber spinning lines to prevent degradation of tensile strength, discoloration, and surface chalking. The additive is dosed directly into the polymer melt or masterbatch before extrusion into monofilaments and tapes.

Downstream process integration

• Incorporated with pigments and process stabilizers in the melt phase before filament extrusion; checked using accelerated weathering cycles and colorfastness assays on test lots.

Final product types

• Synthetic grass blades for sports and landscaping fields
• Outdoor upholstery fibers
• Geotextile yarns

5. Packaging Films for Food & Consumer Goods

Producers of multilayer BOPP, PET, and PE flexible packaging integrate the UV absorber to guard against product spoilage, off-flavor development, and material embrittlement during display and storage. The material is introduced into co-extrusion lines for surface or core layers, depending on desired light barrier and migration control.
