Product protection is enhanced with TOPAS® COC in many packaging, healthcare and industrial applications.
TOPAS COC moisture barrier is exceptional:

Retain air and nitrogen longer with PE-compatible TOPAS COC. Since air is almost 80% nitrogen, N2 barrier is essential to performance of air pillows. Snacks and other foods can benefit from a longer lasting nitrogen-enhanced environment. Inflatable goods will stay inflated longer.

For helium applications such as aerospace balloons, TOPAS COC offers a new way to enhance performance and longevity.

TOPAS polymers provide exceptional moisture, nitrogen, and helium barrier, and we offer an elastomer with unique barrier properties as well.
