Our Porous Plastics Technologies


Our original Vyon® sintered porous plastic offer excellent chemical compatibility, exceptional strength and are resistant to most acids, bases, many organic chemicals and temperatures up to 110ºC (230ºF). Available as sintered porous polyethylene and polypropylene these materials are designed primarily for industrial applications.


BioVyonTM polyethylene materials are designed with our life science and medical customers in mind. From medical device filters, pipette filters to SPE frits this innovative type of porous plastic material are made to demanding regulatory standards as required by the FDA, EP Pharmacopeia and USP.

Specialised Range of BioVyonTM Materials

Through a range of proprietary techniques, Porvair Sciences offers advanced BioVyonTM materials with enhanced performance capabilities. 

BioVyonTM Hydrophilic

Our hydrophilic BioVyon™ material is permanently treated for instant water wettability.

BioVyonTM Hydrophobic/Oleophobic

Our hydrophobic or oleophobic BioVyon™ is permanently treated to prevent the material from wetting-out in many organic solvents.

BioVyonTM Composites

This material immobilises active substances within the sintered porous material, such as chromatography resins, carbon and cellulosic materials.

BioVyonTM Functionalised

Our chemically or biologically active sintered porous material is functionalised with amines, carbonyls, carboxylic acids, linker chains or ligands.

BioVyonTM Ultraclean

Our ultraclean BioVyonTM range offers a high purity material with trace extractables.

BioVyonTM Laminates

Used as a support for membranes, our BioVyon™ laminate material extends the filtration range to 0.1µm for the retention of microorganisms.
