Asaclean Serbia — purging compounds

Purging between color, material or shutdown changeovers protects part quality and cuts scrap and downtime — a slow or incomplete purge shows up as streaking, black specks or contamination carried into the next production run. Perotec Systems supplies Asaclean (Asahi Kasei), the world's best-selling purging compound brand, sold in more than 77 countries.

The range covers general-purpose and economy mechanical grades for routine color and material changes, olefinic-based grades for polypropylene and polyethylene, low-residue grades for transparent and optical parts, food-certified grades for food-contact processing, and high-temperature grades for engineering and super-engineering resins up to 370°C. All grades ship as ready-to-use granules — no pre-drying or mixing — and run on standard injection molding, extrusion and blow molding equipment, including hot runner systems.

Perotec Systems is the Asaclean partner for the region — contact us to match a grade to your resin, process and changeover frequency.

Frequently Asked Questions

How much purging compound is needed per changeover?

Roughly 1–2 barrel volumes; the exact amount depends on machine size and the color or material being changed. Done properly, total consumption is several times lower than flushing with production resin.

Can purging compound pass through hot runners?

Yes — Asaclean U and UB grades are formulated to pass safely through hot runner systems and multi-cavity molds.

Does purging really reduce scrap?

Yes. Faster color and material changes mean fewer streaked transition parts, and regular purging prevents carbonized deposits that later cause black specks on products.
