Shield™ LST-296 is liquid light stabilizers are effective in a broad range of plastics and can help achieve long-term sustainability goals as in the recycling of plastics. We have products formulated with hindered amines (HALS) and UV absorbers. For certain applications, we offer blends of these two products for improved performance. Ultraviolet (UV) radiation from the sun will need the combination of HALS and antioxidants for long-term stability. Polymer photo-oxidation is a combined action of light and oxygen. The visible result of this action is deterioration of the appearance of the polymer as well as mechanical and chemical concerns. Our products can protect against these conditions. We also offer UV absorbers that protect the contents of plastics packaging from ultraviolet rays up to 390 nm.

Guard™ LAO-325 is Heat is a necessary function for molding plastics. However, under higher than normal processing temperatures, it may be necessary to add an additional stabilizer to maintain the integrity of the polymer. Degradation of polymers, due to excessive heat, can have an effect on the process, product stability and screw barrel contamination. Another factor of concern for the industry is the increased use of PCR. Antioxidant additions to the combinations of virgin and PCR resins can provide the heat stability needed to maintain a healthy polymer. Our solutions range from a single functional antioxidant, for processing with higher heat conditions, to multifunctional products that improve heat stability as well as long-term heat aging.
