A useful trial begins before the machine starts. The goal is to evaluate MB-120 Blanco Shalom 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
Processes
- Cold-runner injection molding
- Extrusion
- Blow molding
- Hot runners only after evaluation
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 | 140–210 °C is the published reference range; always remain within the base resin's process window. |
| Dosage or incorporation | 15 g/kg for injection molding with virgin resin; 15–20 g/kg for extrusion, blow molding, and recycled-resin applications. |
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.
- Final opacity changes with wall thickness and base-resin color.
- Hot-runner processing requires prior evaluation.
- This grade is not formulated with FDA-approved materials.
