Quality control begins before NBR latex reaches the glove production line.

A systematic QC program may include checks of:

• Appearance

• Total solids content

• pH

• Viscosity

• Coagulum

• Mechanical film properties

• Storage stability

The specific control items and acceptance limits depend on the product and application.

For glove manufacturers, consistent raw material quality can support more predictable compounding and dipping operations.

However, raw material QC should work together with process control.

Finished-glove testing remains important because the ultimate objective is not simply to meet a latex specification.

It is to consistently produce gloves that meet the required performance.

RUICO applies quality-control procedures to NBR latex intended for glove manufacturing applications and supports customers with relevant technical documentation and product information.
