BLS® 531
Applications: BLS® 531 is an extremely effective UV absorber that is recommended for polypropylene, polyethylene, plasticized PVC, rubber, acrylics, polycarbonate, EVA, and polyester. BLS® 531 is also recommended for use in adhesives and sealants where light stability is a concern. When BLS® 531 is synergistically combined with a Hindered Amine Light Stabilizer (HALS) it is extremely effective in low density and linear low density polyethylene as well as ethylene-vinyl acetate copolymers for agricultural films. This synergistic combination can also be used in high density polyethylene molded articles (i.e. crates). BLS® 531 can also be used synergistically with antioxidants, phosphites, and light stabilizers.
Advantages:
- Highly compatible with a wide range of organic substrates
- Non-staining and low color contribution
- Particularly suitable for thick films, typically > 100 um and thick sections
- Low vapor pressure prevents losses during processing
- Low migration rates reduce danger of blooming
- Improvement of long-term stability
- Low volatility
- Ease of compatibility with other stabilizers
