1️⃣ What Are PU Coated ESD Gloves?

PU coated ESD gloves are static-dissipative gloves designed with a polyurethane coating on the fingertips or palm to enhance grip and precision while maintaining controlled electrostatic discharge performance.

These gloves are widely used in:

• PCB assembly

• SMT production lines

• Semiconductor packaging

• Cleanroom operations

• Precision electronics handling

2️⃣ How PU Coating Works

Polyurethane (PU) coating provides:

• Excellent grip on small components

• High abrasion resistance

• Flexible and lightweight feel

• Low particle shedding (select grades)

In ESD gloves, the base yarn usually includes:

• Carbon fiber

• Conductive filament

• Static dissipative synthetic blends

The coating does not block static control — it works together with the conductive yarn structure to control charge transfer.

3️⃣ Fingertip vs Palm Coated PU Gloves

Most PCB lines prefer fingertip coating for dexterity.

4️⃣ 13 Gauge vs 15 Gauge vs 18 Gauge

Gauge determines thickness and flexibility.

Higher gauge = thinner yarn = better sensitivity.

5️⃣ Electrical Performance

Typical static dissipative range:
10⁶ – 10⁹ ohms (application dependent)

Important factors:

• Test method

• Surface resistance measurement

• Environmental humidity

• Washing cycles

6️⃣ PU vs Nitrile Coated ESD Gloves

PU is ideal for precision handling.
Nitrile is better for harsher environments.

7️⃣ Cleanroom Compatibility

For cleanroom environments:

• Low lint yarn

• Controlled packaging

• Anti-contamination manufacturing

• ISO cleanroom compatibility

PU coated gloves are commonly used in:

• ISO 7

• ISO 8 environments

For higher ISO classes, verify particle shedding data.

8️⃣ Durability & Lifespan

PU gloves typically last:

• 1–3 weeks in standard assembly

• Shorter in abrasive environments

Lifespan depends on:

• Operator workload

• Handling materials

• Cleaning frequency

🔟 Frequently Asked Questions

Are PU gloves anti-static?

Only if engineered with conductive yarn. Standard PU gloves without ESD yarn are not static dissipative.

Can PU gloves be washed?

Some reusable models can be washed under controlled conditions. Performance may change after repeated washing.

Do PU gloves work in humid environments?

Humidity affects static levels. Proper ESD testing should confirm suitability for your environment.

Final Summary

PU coated ESD gloves provide the best balance of:

• Precision

• Static control

• Comfort

• Cost efficiency

They are the most widely adopted glove type in electronics manufacturing environments.
