IRGANOX PS 802
IRGANOX PS 802
Irganox PS 802 is a dialkyl ester of thiodipropionic acid. It is used as a heat stabilizer in combination with a phenolic antioxidant.
In general Irganox PS 802 can be used to improve the long-term heat stability of polymers at recommended levels of 0.05 % – 1 %. In peroxide crosslinked power cables, 0.02 % – 0.03 % Irganox PS 802 in combination with 0.02 % – 0.03 % Irganox 1035.
Applications
- Polymer materials requiring long-term thermal stability
- Polyethylene power cables
- XLPE power cables
- HDPE pipe
- Polypropylene
- Polyolefin under-the-hood automotive applications
- Styrene homo- and copolymers
- Adhesives
Features & Benefits
Irganox PS 802 used in combination with a primary phenolic antioxidant provides long-term heat stabilization to polymeric materials. With the lowest volatility of all BASF thiosynergists, it combines excellent performance with low odor.
