Fireshut® Thermal Expansion Composites
These are thermally expandable rubber products. When heated at high temperature, they expand to five to thirty times their volume to close openings and thereby prevent the intrusion of smoke and the spread of fire.

Types and Shapes


◆Easy-to-handle sponge and tape types
flexibility variance in dimensions, processability, heat insulation and softness

◆Excellent fire resistance
Thermal expansion to form a more solid heat insulation layer
Filling space lead to block smoke

◆Sponge effect -> offers sound and vibration insulation

◆Limited toxic gas emissions
Halogen-free type
