Model: SA-ZPV
Application: Plastic Processing Stabilizer
Features & Benefits
● Prevents ester exchange in polyester or polyester alloy products, improving mechanical property retention.
● Enhances stability of Melt Index (MI) and physical properties during plastic molding.
● Effectively prevents high-temperature degradation during processing in other plastics, while improving ΔE yellow Index in finished products.
Composition
● Alkyl phosphate-type resin
Typical Physical Properties

| Form | Fine granular powder | |
| Color | White to off-white | |
| Volatile matter | <1.5 | % |
Description
● SA-ZPV is an alkyl phosphate-type resin processing stabilizer that prevents resin degradation during processing. In resin processing, SA-ZPV effectively suppresses the activity of residual catalysts in polyesters, forming stable chelates to protect polyester molecular structures.
Table 1: Product Usage Recommendations
| INNOVBLEN | Resin | Recommended Dosage |
| SA-ZPV | PC, PCR | 0.1–0.2% |
| PC/PBT, PC/PET, PBT/PET | 0.1% | |
| PA, PBT | 0.3–0.5% |
Usage Instructions
● Actual dosage may vary depending on screw configuration, processing temperature, and requirements. When using SA-ZPV, mix it uniformly with plastics at a specified ratio. If adding powdered additives, pre-mix SA-ZPV with other powdered additives before blending with plastics to ensure homogeneous dispersion.
