PolyPurge Screw Cleaning Compound: Faster, More Efficient, Cleaner

In injection molding and extrusion production, screw cleaning is often a troublesome task. Especially in medical device manufacturing, customers have high requirements for the products.Cleanliness, color difference, and risk of mixing materials Has extremely high requirements.
Any remaining black spots, mixed materials, or impurities may affect product quality and even pose safety risks, such as compromising the dosage accuracy and safety of critical devices like catheters, syringes, or insulin pens.
Incomplete switching between colors and resin often leads to color differences, black spots, and impurities in the products, seriously affecting quality and productivity.
The long-term accumulation of carbides is more likely to cause screw wear and equipment hazards.
It was precisely in response to these pain points that Jinghan specifically developed the PolyPurge-MH4000 screw cleaning compound. Its mission is simple—to achieve a more thorough cleaning with a smaller amount of material.
In comparative experiments, PolyPurge-MH4000 demonstrated higher efficiency in dealing with carbides and residual resin, while using less material than foreign competitors. This means that when switching colors or resins, companies can resume stable production more quickly, while also reducing defect rates and raw material consumption.

The applicability of this cleaning agent is quite broad, covering common plastics such as PP, PE, ABS, as well as engineering plastics like POM, PBT, PA, PC, and others. Whether it is color changes during regular production or transitions involving high-performance materials, PolyPurge-MH4000 can provide a clean and efficient cleaning effect, ensuring that the switching process no longer becomes a production bottleneck.

Usage Instructions


For processing enterprises, this brings comprehensive value: less downtime, lower overall costs, more stable product quality, and longer equipment lifespan. Often, cleaning agents are not the most conspicuous role in production, but they determine the efficiency of production changeovers and whether an enterprise can maintain competitiveness in a fast-paced market.
