Acrylonitrile content is an important characteristic of NBR and can influence the balance of properties in the final rubber film.

In general, changes in acrylonitrile content can affect properties such as:

• Oil resistance

• Solvent resistance

• Flexibility

• Low-temperature behavior

• Mechanical performance

However, higher acrylonitrile content should not simply be interpreted as better for every glove application.

The appropriate polymer composition depends on the intended application and required property balance.

For example, an industrial glove designed for oil exposure may have different requirements from a thin disposable glove intended primarily for general handling.

NBR latex selection should therefore consider the complete application rather than focusing on a single polymer parameter.

RUICO develops NBR latex with different application requirements in mind, helping manufacturers evaluate the appropriate balance between resistance, flexibility and processing performance.
