AO-1010 is a primary antioxidant based on butylated hydroxytoluene (BHT). It is part of the hindered phenol family and is widely used to protect plastics, elastomers, and rubber materials from heat, air, and processing damage.
It stops oxidation early by neutralizing free radicals and delaying chain breakdown. AO-1010 is effective during extrusion, molding, film blowing, and long-term storage.

Q1: Is AO-1010 safe for food-contact materials?
Some grades comply with FDA and EU food standards. Please confirm the grade before use.
Q2: Can I use it in a recycled plastic system?
Yes. AO-1010 helps reduce thermal stress during reprocessing.
Q3: What’s the best storage condition?
Cool, dry, well-ventilated warehouse. Avoid sunlight or moisture.
Q4: Does it affect color or transparency?
AO-1010 is low in color impact and ideal for clear or white polymers.
Q5: Can I use AO-1010 with other antioxidants?
Yes. It works well with AO-1076 (phosphite) and AO-168 (thioester) for synergistic effects.
