Plastics specialists Wefapress have developed a new material with very high density and hydrophobic properties.
An ultra-high molecular weight low-pressure polyethylene (UHMW-PE), fine-grained “filta-plast” (porous PE) is optimised for filtering liquids and gases, atomisation, gassing and aeration, as well as fluidisation.
The porous structure and chemical resistance of the plastic material permit condensation separation and separation of emulsions or membranes in electrodialysis. filta-plast can also be used as a carrier body for liquids, e.g. in the form of porous sheets.
filta-plast is produced using precise sintering and minimal pressure. A special selection of precisely defined particle sizes, in connection with the process parameters, enables the production of the widest variety of forms with varying pore sizes. filta-plast is available in sheets, rods, tubes or moulded form per customer specification, among others. Fusing with welding mirrors and chemical/mechanical adhesion is possible with this material.
Last but not least, filta-plast is resistant to alcohols, aliphatic hydrocarbons, organic compounds such as industrial oils and is resistant to strong alkalis and acids.
