Application Characteristics
AUSINOX PA-2789 is an Additive Antioxidant Specially recommended in PA Compounding, Regenerating, etc.
The antioxidant Effect offered by the AUSINOX PA-2789 :
- Avoids the Yellowness Formation, ensuring the natural Colour
- Maintains the mechanical Characteristics Also in PA Hand-Made submitted To continuative Heat Process
The best Performances of AUSINOX PA-2789 Are offered In the most critical Situations, Where the Yellowness Formation is typical of these Compounds, As :
- Compounding or Regeneration of PA-6.6 / Glass Fibers reinforced.
In every situation, the natural colour of the Polyamides is assured and preserved.
Addition Levels
The recommended dosages are as follows :
- 0,50 – 0,60 % in PA-6
- 0,60 – 0,80 % in PA-6 / Glass Fibers
- 0,60 – 0,70 % in PA-6.6
- 0,70 - 0,80 % in PA-6.6 / Glass Fibers
NOTE – Avoid the Employ of the AUSINOX PA-2789 with the thermal Stabilizers based on Cu J or in Compounds yet added With Cu J, or in PA Compounds Flame-retarded With Bromine Derivatives in Order to Avoid undesirable Formation of Colorations (Violet, Brown, etc.).
