PUGL Fusion Agent
A process upgrade to the former-cleaning stage, delivered through the coagulant. Dosed at 0.75–4%, it changes how the glove releases from the former — and with it, how often and how aggressively formers need to be cleaned.
What it changes
Conventional lines rely on calcium stearate for release and on an acid–caustic wash to keep former surfaces serviceable. That combination works, and it carries the cost stack described on the homepage: former pitting, equipment corrosion, rinse water, effluent load, cleaning downtime and pitting-driven pinholes.
Fusion Agent is a waterborne, plant-derived polymer added to the coagulant phase. It works alongside a reduced calcium stearate loading rather than replacing the concept of release chemistry, and it changes the condition the former is left in after each cycle — which is what determines the cleaning regime required.
How it is implemented
- No capital equipment. It is dosed into an existing coagulant tank. There is no new plant to install and no line modification.
- Dose rate 0.75–4% of the coagulant, set during qualification against your polymer system and process conditions.
- Stearate is reduced, not simply removed — how far is polymer-system dependent, and the ranges are published below.
- Conversion is an operating change, not a capital project, which is why the commercial question is trial risk rather than payback period.
Why that matters financially
Because there is no capital outlay, there is no payback period to recover in the conventional sense. The relevant questions are the net operating effect per thousand gloves once the cost of Fusion Agent is subtracted, and how much line time the conversion consumes. We model both explicitly in a Factory Performance Assessment, and we show the trial cost as its own line item rather than burying it.

Operational effect
What moves, and where it lands.
These are the directions of change observed in production trials. The size of each change is specific to your line, which is why we model it against your baseline rather than publishing a single percentage.
Cleaning chemistry
↓ Reduced
Acid and caustic consumption falls on qualifying lines.
Cleaning interval
↑ Extended
Longer running between cleaning interventions.
Process water
↓ Reduced
Fewer rinse stages behind the chemical sequence.
Effluent load
↓ Reduced
Lower neutralization and organic load at treatment.
Former life
↑ Extended
Long-horizon estimate — reported separately from verified savings.
Equipment corrosion
↓ Reduced
Less acid mist across the cleaning section.
Pinhole defects
↓ Reduced
Attributable to former surface condition; other causes are unaffected.
Available line hours
↑ Increased
Fewer scheduled cleaning stops.
Compatibility and limits
What Fusion Agent does not do.
Published deliberately, and in full. If you run latex only, we would rather tell you now than three months into an evaluation.
| Polymer system | Calcium stearate | Coating regime | Note |
|---|---|---|---|
| Premium nitrile tightly controlled process |
Can be removed | Single coat achievable | The best case, and the exception rather than the rule. |
| High-quality standard nitrile | ≈ 1.2% → ≈ 0.3% | Double coat usually retained | A substantial reduction, achievable on well-controlled lines. |
| Conventional nitrile | ≈ 1.2% → ≈ 0.8% | Double coat required | The most common configuration in the market. |
| Natural rubber latex & isoprene | 0.8% minimum retained | Double coat required | Fusion Agent provides no anti-blocking effect on latex. If your plant runs latex only, this technology is not for you today. |
Wet-on-wet double coating remains the mass-production standard on most lines. These ranges are indicative; we confirm them during qualification against your specific compound and process conditions.
Nitrile (NBR), natural rubber latex, polyurethane, isoprene, neoprene and acrylic systems — with materially different results in each, as set out above.
Ceramic, stainless steel, aluminum, glass and polymeric formers. Substrate affects the cleaning regime baseline, so it is captured during assessment.
Evidence
What supports the claim.
Fusion Agent has run in production trials over a six-month period, with data collected jointly by PUGL and the manufacturer against an agreed measurement protocol. This data has not been independently audited, and we would rather say so than describe it as verified.
What we can offer instead is better: a trial on your own line, against your own baseline, measured against a protocol you approve in advance.
Before you commit a line
A trial is a production event, not a sample. So we document all of the following in advance:
- Trial scope and quantity required
- Line hours consumed by conversion and ramp
- Expected scrap during the ramp period
- The reversion procedure and how long it takes
- Who from PUGL is on site, and for how long
- The measurement protocol both sides will use
See what this is worth on your line.
Fusion Agent’s value depends on your polymer system, your cleaning regime and your utility costs. An assessment models it against your baseline before any trial is discussed.
