High-density closed cell foams
Web9 de mar. de 2024 · While these are all closed cell foams, not all are suitable for soundproofing projects. Of course, density is important, but you don’t want something too dense, such as PVC. The difference between closed cell and open cell foam is pretty obvious: open cell foam has a more aerated structure, and its cells are connected. WebPolymeric based closed cell foams, such as shape memory polymer foams, contain bubbles. Making these bubbles continuous is called reticulation. Disclosed are embodiments of a device and method to controllably reticulate polymer-based closed cell foams by puncturing the membranes of these polymer-based closed cell foams.
