Drive deflection steps the firmness and flexibility of a bit of foam. It primarily informs you how “soft” the foam is, which can be practical for cushioning applications.
Parts of foam which has a significant PPI (reticulated foam) will allow better air and water movement, making them much better for filtration programs. Foams by using a minimal PPI (neoprene) are superior suited to gaskets and waterproofing. Remember that the thickness of a piece of foam can also impression its skill to restrict or inhibit air and water stream.
