Advances in Leaf Disc Capsule Filters for Polymer Melt Applications

Porvair Filtration Group, suppliers of innovative and performance driven filtration equipment to the polymer melt industry for over 25 years, have made advances in leaf disc capsule filter design and filter media selection that provides controlled filtration of difficult polymers resulting in high specification end products.

The leaf disc capsule filter design uses an innovative hard hub that maximises the available filtration area, leading to lower pressure drop, shorter residence times and reduced risk of degradation. The photo etched separator has a non-perforated edge, which improves weld strength at a typical failure point.  This combined with bespoke media selection in stainless steel powder or fibre with a wide range of filtration efficiencies gives optimum performance with added strength and low pressure drop.

Ideally suited to PET film manufacture, the leaf disc capsules produce a singular downstream flow path eliminating the need for mixers and preventing flow lines in finished film. The capsules are readily cleanable and available in industry standard designs and dimensions with diameters of 7", 10" and 12" using optional loose or welded spiders.

Porvair’s high efficiency filters, used throughout the world by many prestigious polymer manufacturers and convertors, offer lowest capital cost combined with ease of replacement, shorter process downtimes and reduced overheads. Highlighted in a new brochure on Polymer Filtration, Porvair’s range of industry specific filters includes candles, leaf disc, needles and spin packs for polymer melt and disposable cartridges for monomer and precursor applications.
