These answers summarize only the published scope for the family. When resin, equipment, or end use changes, the recommendation must be reviewed.
What is AD-301 Expanso Raywan?
AD-301 is evaluated when a project seeks a somewhat lighter part through chemical foaming. Results depend on resin, temperature, wall thickness, and process.
Which resins can be evaluated?
Published information lists: 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. Final compatibility must be confirmed in the actual formulation.
Which processes are documented?
Injection molding; Extrusion; Rotational molding.
Which temperature reference should be used?
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.
What dosage or incorporation method is recommended?
The product page does not publish one universal dosage. Establish it through trials for the resin, geometry, and target density.
Which limits should be reviewed before production?
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.
