A useful trial begins before the machine starts. The goal is to evaluate AD-301 Expanso Raywan under conditions representative of the finished part and leave a record that can be repeated.
1. Document the baseline
Record product grade and lot, resin, recycled content, process, machine, normal temperature, wall thickness, and the visual or functional standard.
2. Confirm the documented scope
Resins
- High-density polyethylene (HDPE)
- Low-density polyethylene (LDPE)
- Linear low-density polyethylene (LLDPE)
- Polypropylene (PP)
- General-purpose and impact polystyrene
- Rigid and flexible PVC compounds
- Solid TPU
- EVA
- SAN
Processes
- Injection molding
- Extrusion
- Rotational molding
3. Prepare the blend
Measure by weight, use clean equipment, and prevent carryover from the previous material. Retain samples of the resin and concentrate used in the trial.
| Variable | Published reference |
|---|---|
| Temperature | Decomposition is listed at 190–210 °C. The published table gives 190–210 °C for injection, 180–220 °C for extrusion, and 170–200 °C for rotational molding. |
| Dosage or incorporation | The product page does not publish one universal dosage. Establish it through trials for the resin, geometry, and target density. |
4. Run a controlled trial
- Stabilize the equipment with the base resin.
- Introduce the blend without changing several variables at once.
- Separate the first transition parts.
- Record every dosage, temperature, or residence-time adjustment.
- Retain identified samples from the stable run.
5. Evaluate and decide
Compare appearance, dispersion, processing behavior, and part requirements against the initial acceptance criteria. When a change is needed, alter one controlled variable per trial.
- Do not promise a fixed weight reduction without testing.
- Cell structure and finish change with temperature and residence time.
- Confirm that the process window activates the additive without degrading the resin.
