Antioxidant A 1076 is a sterically hindered phenolic antioxidant. It is an effective, non-discoloring stabilizer that provides excellent long-term heat stability by preventing thermo-oxidative degradation during processing and service life. This antioxidant also provides good compatibility with resins and excellent extraction resistance. It can be used in a wide variety of organic substrates such as plastics, synthetic fibers, elastomers, adhesives, waxes, oils, and fats.
Material Description: Antioxidant and Thermal Stabilizer
Antioxidaint A 1076 is a primary antioxidant that can be applied in polyolefins, such as polyethylene, polypropylene, polybutene-1 and other polymers such as engineering plastics, styrene homo- and copolymers, polyurethanes, elastomers, adhesives, and other organic substrates. This high molecular weight phenolic antioxidant also provides excellent stabilization in other polymers such as styrenics, rubber modified styrenics including ABS, SAN and segmented block copolymers, saturated and unsaturated elastomers, PVC, urethane and acrylic coatings, adhesives and petroleum products.
Loading Instructions:
The loading data and results are based on laboratory work (and field-testing) under controlled conditions and do not necessarily indicate the result that the buyer or user will attain. For this reason we strongly recommend testing of your own system under the actual conditions of processing and end-use prior to full scale testing. The recommended loading concentrations of Antioxidant A 1076 in the polymers range between 500 ppm and 2000 ppm. In polyolefins the loading concentrations range between 0.1% and 0.4% depending on substrate, processing conditions, and long-term stability requirements. Concentration levels of Antioxidant A 1076 in hot melt adhesives range from 0.2% to 1%, and in synthetic tackifier resins, Antioxidant A 1076 concentrations range between 0.1% and 0.5%. Exact loading must be determined by compositions of the specific polymer system.
Advantages:
Highly compatible with a wide range of organic substrates
Easily incorporated by melting techniques due to its low melting point
Non-staining and non-discoloring
Excellent resistance to extraction
Odorless and tasteless
Improvement of long-term stability
Low volatility
Extensive FDA clearances
Ease of compatibility with other stabilizers
Packaging:
Antioxidant A 1076 is available in powder form in a 25 kg net weight, with an inner PE liner.
Storage:
This product may be stored up to two years in a sealed container. Containers should be stored in a cool, dry area. Extended storage at elevated temperatures or exposure to direct heat or sunlight could reduce product life. Keep containers sealed when not in use.
