Research Progress in Poly (vinyl formal) Cellular Plastics

doi:10.19491/j.issn.1001-9278.2011.04.003

Abstract

Abstract: The properties and preparation of poly (vinyl formal) (PVFM) cellular plastics were reviewed in this paper. The factors influencing the properties of PVFM cellular plastics were particularly discussed, including the kinds of poly(vinyl alcohol), water content, formaldehyde content, and acid content. The molding methods of PVFM cellular plastics were introduced, including bubbling by foaming agent, mixing, and pore-forming agent. The main applications of PVFM cellular plastics were also introduced such as clean and cosmetics, filtering and damping, medical and biological carrier, and degradable materials.

Key words: poly(vinyl alcohol), formaldehyde, cellular plastics, preparation, poly (vinyl formal)
