Applications
Advantages: Alternative for recycling and stabilization of EAFD, by encapsulating the waste in an ethylene propylene diene monomer (EPDM) matrix and the addition of organic compounds that act as phase change materials (PCM), achieving a flexible dense sheet with acoustic and thermal properties. Applications: Sound insulation panels, multilayer wall partitions, underflooring, flexible membranes
