Fire stopping seal for versatile applications

PROMASEAL®-PL is a graphite-based intumescent fire protection laminate that creates high pressure on expansion when exposed to temperatures of approx. 150 °C. PROMASEAL®-PL forms a stable and compact char that closes gaps and other openings rapidly. This ensures a secure seal against the spread of smoke and fire inside the application or construction.
