Foam Gasket

How to Choose the Right Foam

The densities, compressibilities and deflections will affect the foam in its function. Higher is better for sound absorption (12400FES vs. 10200FCU)

Thicker material is better for sound absorption especially for high frequency (not a lot of effect in low and mid frequency)

You can choose a convoluted foam (12499FCO) when you have low and mid frequency and when you have space.

In application where the integrity of acoustical foam must be preserved, perforated vinyl, metallised polyester film, aluminum or other substrates can be bonded to it.
