■ Purging Compound for Plastic Molding Machines with New Materials

ecomaru is the world’s first purging compound for plastic molding machines containing glass wool. Compared with conventional purging compounds containing glass fiber, it provides higher cleaning performance.

■ Benefits Delivered by Its High Cleaning Performance

1. Dramatic Reduction in Black Dot Defect Rates

The high cleaning performance prevents resin residue from remaining inside the molding machine, dramatically reducing black dot defects caused by carry‑over of previous materials.

2. Eliminates the Second Purge, Reducing Effort and Cost

Conventional GF‑infused purging compounds typically recommend a two‑step purge using a discharge grade. In contrast, ecomaru’s superior dischargeability allows changeover to be completed by simply flushing with the subsequent resin, so a second purge is generally unnecessary. This substantially reduces labor and cost.

Note: Depending on the customer’s operating environment, a secondary purge with PP/PE may still be required.

3. Environmental Benefits (Reduction of Usage and Waste)

Superior cleaning and discharge performance enables approximately a 70% reduction in usage and waste compared with conventional products, contributing to a lower environmental footprint.
