Product features and applications
●UV-622 is a polymerized blocked amine light stabilizer (HALS), effective in a variety of polymers and applications, suitable for PE materials (injection molding, rolling molding, film materials and tapes), EVA, PP fiber, polyurethane, polyacetal, elastomer, adhesives and seals, etc. The product has good light stabilization effect on the material containing carbon black system
Depending on the use, the general addition level of UV-622 is between 0.05 and 1.5%. Appropriate tests must be performed to determine whether the amount added for a particular purpose is appropriate. The product is used in conjunction with other light stabilizers that exhibit synergic effects, such as high molecular HALS (e.g. Uv-944 UV-119), benzoic acid, and UV absorbers.
Characteristics
- do not change color
- Low volatilization and anti-migration
- Weak alkalinity, reducing interactions with fuels and other stabilizers
- Widely applicable to food contact materials
packaging
25 kg plastic drum
Handling and storage
Please refer to the safety data sheet before handling or using the product.
Shelf life is one year if stored properly in a dry area below 25°C
Application
The products is the typical representative of hindered phenol antioxidants, non-poisonous, nondiscolouring as well as nonstaining and is an excellent top-quality approved in international. It is widely used in a variety of polymer materials, such as polypropylene, polyethylene, polyester, polyrethane, polystyrene, polyxymethylene, PBT, ABS, polyamide, synthetic rubber and so on. It is also a high grade antioxidant for natural and synthetic oil.
