Production of cellular polymers without solid outer skins by gas dissolution foaming: A long-sought step towards new applications

Autor: D. Cuadra-Rodríguez, S. Barroso-Solares, M.A. Rodríguez-Pérez, J. Pinto

Publikováno v: Materials & Design, Vol 217, Iss , Pp 110648- (2022)

An innovative approach to reduce and eliminate the non-foamed solid skins of the cellular polymers fabricated by gas dissolution foaming is presented in this work. The incorporation of a flexible gas diffusion barrier on the polymer surfaces during t
