Product Features:
1. Odorless, does not impart odor to polymers during use.
2. Insensitive to metal ions.
3. Non-flammable, non-explosive, non-toxic, safe and harmless for use.
4. Excellent stability with strong UV absorption properties.
5. Good thermal stability, suitable for plastic products requiring high-temperature processing.
6. Virtually no visible light absorption, particularly suitable for colorless transparent and light-colored products.
IV. Product Applications:
UV absorber UV-P is a highly efficient UV absorber capable of effectively absorbing ultraviolet light in the 290-400 nm range. It is primarily used in polyvinyl chloride (PVC), polypropylene (PP), unsaturated resins, polycarbonate (PC), polymethyl methacrylate (PMMA), polyethylene (PE), ABS resin, epoxy resin, fiber resin, etc. This product exhibits negligible visible light absorption, making it particularly suitable for colorless transparent and tinted products. Typical dosage ranges from 0.1-0.5% for thin products and 0.05-0.2% for thick products.
V. Packaging:
20 kg/drum. Store in a cool, dry, well-ventilated warehouse, avoiding direct sunlight, high temperatures, and humid environments.
