Barrier - Nitrogen

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.

Elastomers are usually poor barriers. TOPAS Elastomer E-140 is surprisingly low in nitrogen permeation.
