TDS-derived technical profile
Key values listed for A-868
The following technical values are taken from the current TDS to support grade selection and initial formulation work.
| Property | Listed value | Method |
|---|---|---|
| Intrinsic viscosity | 0.935 ± 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 impact and toughness evaluation
- Clarity-conscious formulation comparison
- Controlled small-batch processing trial
How to prepare the first evaluation
- 01
Blend the grade with PET resin for 5–8 minutes before processing.
- 02
Keep the base resin, thickness and processing conditions consistent between comparison samples.
- 03
Evaluate the stabilized molded result after at least 24 hours.
