Ecoflex® 400 Sustrate Support Mat (PDF) - Unifrax

Canning Performance
Ecoflex 400 is typically installed at a nominal gap bulk density (GBD) of 0.40 g/cm 3 . The room temperature
compression behavior of Ecoflex 400 is shown in Figure 1. The GBD range for each specific application will be
defined according to the requirements for holding force and substrate strength.

Erosion Resistance
Support mat erosion may occur as a result of improper support mat installation or due to lack of holding force of
the fiber matrix. Different types of support mat are more susceptible to erosion than others. Ecoflex 400 has been
designed specifically to present a low erosion profile. Figure 2 presents comparative erosion resistance for different
support mat types as a function of GBD.
