Title:
PRODUCTION OF FILTER BODY
Document Type and Number:
Japanese Patent JPS62250909
Kind Code:
A
Abstract:
A process for preparing a porous polymeric filter body in which a deformable, porous, polymeric body, in which the porosity is in the form of a series of cavities jointed by interconnecting holes constituting a series of pathways through the body, is deformed comprises imparting a deformation to the polymeric body so as to change the dimensions of pathways so as to effect the filtering characteristics of the body with the polymeric body itself retaining the deformation so as to form a substantially rigid filter body. Filter bodies can thus be pre-formed or can be formed in situ to desired filtration characteristics.
