介绍 | BLS® 1770 is a low molecular weight hindered amine light stabilizer that provides excellent light stability for thick sections, but can also be used for articles with a high surface area such as films and tapes. BLS® 1770 provides effective ultraviolet light protection for applications demanding particularly high light stability. It provides outstanding long-term stability by a radical trapping mechanism similar to that of hindered phenols. Significant levels of stabilization are achieved at relatively low concentrations. When compounded, BLS® 1770 imparts no negative effects on a substrate's initial color, its low dust, free-flowing form makes it exceptionally convenient to handle. Applications: BLS® 1770 is a hindered amine light stabilizer offering excellent protection against ultraviolet degradation. BLS® 1770 areas of application includes polypropylene, impact modified polypropylene, TPO, EPDM, polystyrene, impact polystyrene, ABS, SAN, ASA, and polyurethanes. In addition, BLS® 1770 can be highly effective in polyacetals and polyamides. BLS® 1770 is particularly effective in polypropylene thick sections, but it can also be used for articles with a high specific surface area such as films and tapes. BLS® 1770 can be synergistically combined with other stabilizers like BLS® 1328, and BLS® 1710. Advantages:
