Which NBR Latex Fits Your Glove Application?

Nitrile gloves may look similar, but their requirements can be quite different depending on the application.

The right NBR latex is not simply about choosing a “higher” or “lower” grade. It is about matching the latex characteristics with the glove structure, production process and end-use requirements.

1. Medical & Examination Gloves 

Typical focus:
• Film uniformity
• Tensile strength and elongation
• Low residual odor
• Softness and flexibility
• Skin-contact considerations
• Regulatory requirements

For these applications, latex selection needs to consider both film performance and the requirements of the finished glove.

2. Disposable Industrial Gloves

These gloves may require a balance between comfort and protection.

Typical focus:
• Good film strength
• Flexibility
• Chemical resistance
• Low pinhole risk
• Stable dipping process
• Cost-performance balance

The formulation may be adjusted depending on whether the glove is intended for general handling, cleaning, food-related applications or other industrial uses.

3. Textured / Sanded Industrial Gloves

Here, the surface becomes especially important.

Typical focus:
• Grip
• Abrasion resistance
• Coating adhesion
• Tear resistance
• Surface texture
• Mechanical durability

The NBR latex needs to work well with the specific surface treatment and coating process.

4. Supported & Coated Industrial Gloves

For fabric-supported gloves, the requirements can be different again.

The latex may need to provide:
• Strong adhesion to textile substrates
• Good penetration control
• Flexibility after drying
• Abrasion resistance
• Stable coating viscosity
• Consistent coating thickness

One NBR latex does not necessarily fit every glove.

A latex suitable for medical or disposable gloves may also be considered for certain industrial glove applications, provided the final formulation and glove performance meet the requirements.

However, an industrial-glove latex should not automatically be considered suitable for medical gloves without the necessary application and regulatory evaluation.

The right question is not “Which grade is better?”

It is:

“Which latex characteristics match the glove I am producing?”

At RUICO, we develop NBR latex for different glove applications and work with customers based on their dipping process, formulation and final glove requirements.
