Viscosity is an important parameter when evaluating NBR latex for dipped gloves.

However, viscosity should not be considered independently from total solids, formulation, additives and dipping conditions.

The practical effect of viscosity can influence:

• Coating behavior

• Film build

• Flow

• Processing stability

• Surface appearance

A viscosity target suitable for one production system may not necessarily be suitable for another.

For this reason, manufacturers should evaluate NBR latex under their actual formulation and dipping conditions.

When changing latex, it can be useful to monitor both the material itself and the finished glove.

A structured trial may include:

1. Latex stability evaluation

2. Formulation compatibility

3. Dipping trial

4. Film thickness evaluation

5. Finished-glove testing

This provides a more complete understanding of how the latex performs in production.

RUICO can support application evaluation based on the customer's existing process and target specifications.
