Overview
BLS 1880PE (167078-06-0) and BLS 1880PP (167078-06-0) are monomeric hindered amine light stabilizers (HALS) that provide excellent light stability in thick-section polypropylene and TPO applications. These products often outperform other low-molecular weight HALS (e.g. BLS® 1770) even when used at reduced concentrations. BLS 1880PE and BLS 1880PP are also non-discoloring and have excellent compatibility with polyolefin substrates. The pellet product forms makes the products easy to handle and dose, and help to minimize worker exposure.

Guidelines for Use
Recommended concentrations in PP and TPO range from 0.05 to 1.0%. The use of the products in combination with a benzoate light stabilizer such as BLS 2908 is recommended for applications with the most demanding weathering requirements. In some cases the addition of a UV absorber such as BLS 531 or BLS 1326 can provide further improvements in performance. The exact formulation to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use. Please contact Mayzo for specific recommendations.
