AppliedProduct Overview
PowerNox™ TDP helps limit oxidative degradation during thermal processing and supports color retention and processing stability. The TDS describes applications across several polymer systems, coating formulations and selected lubricants.
Key Features
- Phenol-free liquid trialkyl phosphite.
- Functions as a secondary antioxidant and processing stabilizer.
- Helps maintain color consistency during thermal processing.
- Supports initial color and clarity in rigid and plasticized PVC.
- Helps reduce oxidative discoloration and processing scorch in polyurethane foams.

Selected values from the original TDS. Refer to that document for conditions and whether values are typical or specification limits.
Typical Applications
- Polyolefins, polyurethanes, PVC, ABS and PET.
- Coating formulations.
- Selected lubricant formulations requiring phosphite-based stabilization.
Technical Considerations
The suggested TDS dosage is 0.1–2.0%. The optimum level depends on the polymer, processing conditions and required stabilization performance.
Keep the container tightly closed and protect the product from moisture. The original TDS gives a 12-month shelf life from manufacture in unopened packaging under the stated storage conditions.
