FAQ

Q1 How to use Antioxidant 168?
Antioxidant 168 can be added via dry blending, masterbatch, or direct dosing into the extruder. For optimal dispersion, it is recommended to pre-mix with the polymer powder or granules. It is stable under most processing temperatures up to 300℃.
Q2 What is the recommended dosage?
Typically used at 0.1% - 0.3% by weight of the polymer. When used in combination with primary antioxidants (like 1010 or 1076), a common ratio is 1:1 or 2:1 (168 : primary). Exact dosage depends on the polymer type, processing conditions, and end-use requirements.
Polyolefins (PP/PE): 0.1 - 0.2%
• Engineering Plastics (ABS/PC): 0.2 - 0.4%
• For synergistic blends: Combine with 1010 or 1076 for optimal thermal stability.
Q3 Which solvent systems are compatible?
Soluble in chloroform, toluene.
Q4 What's Packages of iSuoChem Antioxidant 168?
📦 Packaging: 25kg/carton, 500kgs/pallet
🚢 Container Quantity: 10mts/20'fcl with pallet / 12mts/20'fcl without pallet
