Vyon® Sintered Porous Plastics

Our Vyon^® sintered porous plastic materials offer excellent chemical compatibility, exceptional strength and are resistant to most acids, bases, many organic chemicals and temperatures up to 110ºC (230ºF).

Typical applications

• Applicators (make-up, ink, fragrance, cleaning products)
• Domestic water filters
• Noise supression (pump dampeners)
• Activated carbon filters
• Chemical filters
• Air and dust filters
• Fluidisation and aeration of bulk solids including foodstuff (flour, sugar, grains) or industrial chemicals (polymers, cement, paints)
• Battery vents
• Pneumatic silencers
• Water and effluent aeration (sand filtration bed support and underdrain aeration / diffusion
• Fragrance eminators
• Gas sensor protection
• Fisheries / fish farms (water oxygenation)
• Metal electroplating (chemical mixing)
• Vacuum platens and cones
• Vacuum hold down table covers / air vice/ sacrificial cutting surfaces

  A versatile material that can be manufactured in a variety of shapes and sizes.

• Narrow controlled pore size distribution
  A very efficient and effective filtration material.

• High and even porosity
  Low pressure drop and even flow.

• Chemically inert
  Resistant to many chemicals making it suitable for many applications.

Sheet and Roll

Rolls and sheets of Vyon^® can be manufactured in widths over 1,050 mm wide to lengths bespoke to our customer requirements. Our standard product range of Vyon® sheets offers 1 m x 1 m sizes in many of our materials. Sheets can also be cut down to size or welded together.

Cut Discs

With single and multi-impression rotary cutters we can convert Vyon^® porous plastic rolls into discs and washers. Our versatile approach means we can offer rotary cut products in diameters ranging from 3 mm to 100 mm using any of our Vyon^® roll materials up to 4.75 mm thick. Our rotary cut discs have excellent edge finish, which along with their rigid material properties, makes them ideal in automated product assembly.

Fabrications

Vyon^® roll and sheet material can be fabricated to create alternative 3D shapes including cones and tubes. Tubes are expertly seam welded and can be supplied with additional features such as end caps or adaptors. These tubes can be further processed into standard or customised filter cartridges for liquid and gas filtration, sparging and other applications.

Mouldings

Our state-of-the-art Vyon^® moulding facility allows for simple, complex and intricate component manufacture. We offer an elevated level of design from a large selection of material options. Our moulding expertise allows us to offer moulded products in varying levels of complexity; shapes may vary from simple pipette tip filters or sample preparation frits to highly complex shapes. Vyon^® moulded components (2D & 3D) can be further enhanced using additives; including CMC for self-sealing properties, colours or activated compounds such as silica to create a composite frit for SPE.

Machined Shapes

Transforming Vyon^® materials into simple and complex products is no challenge for Porvair Sciences. Using temperature and humidity-controlled CNC (Computer Numerical Controlled) routing facilities offers a versatile way to create complex shapes. This machining process enables us to create clean cut products with well-defined edges ensuring a good fit into components such as industrial scale process chromatography columns and filter housings.

Punched Parts

Complex flat shapes (e.g. clover), which cannot be rotary cut, can be expertly converted with precision from Vyon^® roll material using a punching method. Vyon® punched shapes exhibit the same outstanding quality as our other cut products.
