Technical Specifications

Industrial Applications

This UV stabilizer is extensively utilized across the plastics industry to enhance the durability of various resin systems. It is particularly effective in polyolefin applications, including polyethylene (PE) and polypropylene (PP), where it safeguards against UV-induced cracking and fading. The product demonstrates outstanding compatibility with polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), and ABS resins.

For manufacturers producing polypropylene fibers, ethylene vinyl acetate (EVA), and plexiglass, this additive offers critical protection against environmental stressors. Its ability to absorb almost no visible light ensures that the final product maintains its clarity and color integrity, making it especially suitable for colorless, transparent, and light-colored articles where aesthetic appeal is crucial.

Usage Recommendations

To achieve optimal stabilization results, the recommended dosage varies depending on the polymer matrix and the specific exposure conditions. For polyolefin systems, a concentration range of 0.2% to 0.6% is generally advised. In PVC applications, usage levels between 0.2% and 0.5% are typical, while ABS resin formulations benefit from concentrations ranging from 0.3% to 0.5%. Precise formulation guidance should be established through pilot testing to match specific performance benchmarks.

Storage & Handling

To maintain product integrity, store this material in a cool, ventilated warehouse away from direct sunlight and heat sources. Containers should remain sealed to prevent moisture absorption and contamination. During transportation, avoid exposure to high temperatures. When handled according to standard industrial safety protocols, this product presents minimal hazard risks, classified under Hazard Class 3 for shipping purposes. Packaging is typically provided in cardboard drums lined with plastic bags, with a net weight of 20kg per unit.
