A-865
Transparent toughening granule for SAN and AS applications
A transparent granule positioned for SAN and AS trials where flexibility, impact strength and toughness need to improve without an obvious loss of clarity.

Key values listed for A-865
The following technical values are taken from the current TDS to support grade selection and initial formulation work.
| Property | Listed value | Method |
|---|---|---|
| Density | 1.26 g/cm³ | — |
| MFI | 15 g/10 min | — |
| Molecular weight | >300,000 | — |
| Tensile strength | 52 MPa | ASTM D638 |
| Elongation at break | 530% | ASTM D638 |
| Flexural modulus | 2,130 MPa | ASTM D790 |
| Haze | <1% | ASTM D1003 |
| Light transmittance | 89% | ASTM D1003 |
| Ash | <0.05% | — |
| Moisture | <0.2% | — |
What this grade is positioned to support
- SAN / AS impact and toughness evaluation
- Clarity-conscious formulation comparison
- Controlled small-batch processing trial
How to prepare the first evaluation
- 01
Blend the grade with SAN / AS 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.
Why this model is a separate evaluation route
A-865 is the SAN/AS-specific transparent route. The source TDS lists less than 1% haze, 89% light transmittance and 530% elongation at break for this grade.
What the source document does not establish
- Use A-865 for SAN or AS trials; do not transfer its optical values to PC, PMMA, PET or PP.
- Glass fibre can affect the modification result, so keep reinforcement and base resin consistent.
- Use a flat, non-porous specimen and wait at least 24 hours before comparing optical and mechanical results.
