Hello, this is the sales manager from Gaolebo Cleanroom Gloves.
Many engineers and purchasing teams assume that any glove with ESD protection can be used inside a cleanroom. In reality, static control and contamination control are two different requirements.
A glove may provide excellent electrostatic discharge (ESD) performance while still generating unacceptable levels of particles. Understanding how different ESD gloves work helps manufacturers choose products that meet both electrostatic and cleanroom requirements.

A glove suitable for a cleanroom must address both:

Some ESD gloves are designed primarily for static dissipation and may not meet cleanroom cleanliness requirements.

Traditional knitted ESD gloves achieve static dissipation by weaving conductive carbon fibers into polyester yarns.

The conductive fibers create pathways that allow static charges to dissipate gradually.

Advantages:

Limitations:

These gloves are commonly used in electronics assembly but are often unsuitable for cleanroom applications requiring ISO Class 7 or better.

PU-coated ESD gloves combine conductive knitted liners with polyurethane coatings on the fingertips or palms.

The PU coating improves grip and reduces direct fabric shedding.

The conductive function often depends on the integrity of the coating and exposed conductive pathways.

ESD nitrile gloves typically achieve static control by adding conductive additives or antistatic compounds to the nitrile formulation.

Depending on formulation, conductivity may not remain stable throughout the product's service life.

Some gloves achieve antistatic performance through surface-applied antistatic agents.

These treatments create a conductive layer that helps dissipate static charges.

This is one of the most common reasons why some antistatic gloves fail to maintain performance during long-term use.

Modern cleanroom seamless gloves can achieve permanent ESD performance by integrating conductive fibers directly into the polyester substrate beneath the coating layer.

Instead of relying solely on surface treatments, conductive fibers are knitted horizontally throughout the glove structure.

As long as the glove surface remains intact, the conductive network remains functional.

For manufacturers requiring both contamination control and stable electrostatic protection, this design offers a practical solution.

Not all ESD gloves are suitable for cleanrooms. The key difference lies in whether the glove can simultaneously control electrostatic discharge and particle contamination. Understanding how different technologies achieve ESD performance helps manufacturers select gloves that meet both cleanliness and reliability requirements.
