What is Chimassorb 119 CAS 106990-43-6？
Chimassorb 119 is a white powder with a molecular formula of C132H250N32 and a molecular weight of 2285.61. Chimassorb 119 is soluble in chloroform, methylene chloride and toluene. Chimassorb 119 is a substance that improves the light stability of polymer materials. It can shield ultraviolet light waves and reduce the transmission of ultraviolet light.
Advantages of using Chimassorb 119
1. Ultra-high molecular weight, low volatility, resistant to migration and water extraction. During extrusion and injection molding, there is almost no volatile smoke; the products can be used outdoors for a long time without flaking or frosting, and the advantages of agricultural films and outdoor products in resisting rain erosion are prominent.
2. Low alkalinity, resistant to weak acidic environment: can tolerate acidic pesticides, acidic fillers / color powders; suitable for agricultural greenhouse films, avoiding the poisoning and failure of common HALS when encountering acidic media; the performance of the talc-filled PP system is excellent.
3. The colored products have excellent color retention performance, reducing interference with pigments and color mother, and the outdoor weather resistance color difference of colored polyolefins is small, and they are not prone to fading and color change.
4. Chimassorb 119 has good compatibility with PP, PE, EVA, TPO, EPDM, PA, ABS, ASA, and powder coatings; it can be compounded with UV absorbers and antioxidants, and the synergistic effect is significant.
5. Chimassorb 119 has long-term thermal stability, and at the same time improves the thermal oxidation aging performance of the products, suitable for fibers and automotive exterior parts.

Application
Chimassorb 119 is especially suitable for the use of PE agricultural greenhouse film, PP fiber, PP filled talc powder, TPO auto parts. In addition to powder coatings, it can also be used for EVA, EPDM, PA, PET, PMMA and other materials. Chimassorb 119 is used as an analytical reagent, coagulant and radioactive phosphorus reagent.
Packaging and Storage
25kg/drum or according to customer requirements.
Storage temperature: Avoid direct sunlight; Keep away from heat sources; Do not stack at high temperatures to prevent particle adhesion and agglomeration; Store in a dry environment with a relative humidity of 40-70%; Pay attention to anti-static in a dry environment.
Store in an airtight manner, using a PE bag liner in a cardboard barrel; Do not leave it open to prevent moisture absorption and dust contamination; The product is in solid particles, and static electricity is likely to be generated in a dry environment. Be careful to prevent static electricity during operation.
Separate storage: Keep away from strong oxidants and strong acids; Avoid storing together with strong acid-based additives; Although it can withstand weak acidity, it should not come into long-term contact with concentrated acid.
Original factory sealed shelf life: 24 months; After opening, tightly seal the inner bag and use it within 12 months.
FAQ
Q: Can it be used together with acidic additives and acidic agricultural chemical additives?
A: It can tolerate weakly acidic environments and is suitable for contact with acidic pesticides on agricultural films. It cannot be exposed to strong acids for a long time. Strong acids will deactivate the blocked amine functional groups and lose their light-stabilizing effect.
Q: What are the benefits of using it in combination with UV absorbers?
A: 119 (HALS) free radical capture + UV absorber synergy significantly improves outdoor weathering life. It is a standard combination for outdoor plastics and is recommended for combined use.
Q: If there is a lump during storage, does the product become ineffective?
A: Slight compression of the lump, after crushing and testing, if it is qualified, it can be used normally; severe melting and lumping due to moisture and heat indicates local overheating. It is not recommended for use.
Q: What is the minimum order quantity (MOQ)?
A: For industrial bulk goods, the regular MOQ is 25 kg; small samples can be provided for formula testing. Samples are charged for, and the sample fee can be negotiated as a deduction for large order.
Q: What is the delivery lead time?
A: For in-stock products: 3-7 working days after receiving the full payment, the goods will be arranged for shipment.
For high-purity customized specifications orders: 15-22 working days; confirm the inventory before placing the order.
