Changing an NBR latex supplier requires more than comparing price and technical data.

A structured evaluation can include several stages.

1. Raw Material Evaluation

Review:

• TSC

• pH

• Viscosity

• Coagulum

• Stability

• Basic film properties

2. Formulation Trial

Evaluate compatibility with the existing formulation and additives.

3. Dipping Trial

Observe:

• Film formation

• Deposition

• Surface appearance

• Process stability

4. Finished Glove Evaluation

Compare relevant properties such as:

• Tensile strength

• Elongation

• Tear resistance

• Abrasion

• Grip

• Chemical resistance

5. Production Validation

Confirm consistency under actual manufacturing conditions.

This approach helps distinguish between a material that performs well in a laboratory test and one that can be practically implemented in production.

RUICO can support customers through application-oriented NBR latex evaluation based on their target glove and production process.
