Flame Barrier Gaskets

Custom sized flame barriers protect products against damage and people against injury from fire.

Flame Barriers made from proven materials help ensure device safety and reliability.

When a product can be exposed to flame, whether as part of its intended use or as a known hazard, manufacturers can reduce the risk of damage to the product or injury to the user by incorporating flame barriers in the product design. We use materials from trusted suppliers to fabricate flame barriers for applications in multiple industries. We can die-cut these materials and convert them into custom shapes to meet your requirements.
