25 kg paper-poly pouch
TDS-derived technical profile
Key values listed for A-8688
The following technical values are taken from the current TDS to support grade selection and initial formulation work.
| Property | Listed value | Method |
|---|---|---|
| Intrinsic viscosity | 0.95 ± 0.015 dl/g | ASTM D4603 |
| Color Lb | >86 | ColorQuest XE |
| Acid value | ≤36 meq/kg | GB 17931 |
| Melting point | 250 ± 3°C | DSC |
| Ash | 0.01-0.05% | GB 17931 |
| Solid particles | ≤3 mm | GB/T 2000 |
What this grade is positioned to support
- PET heat-deformation resistance
- High-temperature shape retention
- Transparency-conscious thermal trial
How to prepare the first evaluation
- 01
Set the required service or test temperature before choosing dosage.
- 02
Blend A-8688 with PET for 5-8 minutes.
- 03
Proceed by extrusion, injection molding or blow molding and evaluate after at least 24 hours.
