Additional Intellectual Property Licences

Porvair PLC 18 November 1999 Announces two additional intellectual property licences Porvair plc, the advanced materials Group, today announces the addition of two royalty based intellectual property licences, both at early stages of commercial development, to its materials technology portfolio. CMZP, licensed from a US academic institution, is a unique ceramic formulation that will enhance Porvair's existing MicromassTM ceramic technology, which produces ceramic parts for a variety of applications, such as kiln furniture and catalytic media, at a fraction of the weight of conventional products. ZtEd, licensed from a South African manufacturer, is a proprietary advanced ceramic with extremely low expansion and contraction characteristics that make it particularly suitable in various molten metals handling applications. Commenting on these licences, Ben Stocks, Chief Executive of Porvair plc said : The two royalty based licences announced today are in the early stages of commercial development, and will be brought to market by our advanced ceramics subsidiary, Selee Corp. We have been developing technology licences through 1999 as a means of enhancing and exploiting our materials technology portfolio. We envisage further licensing activity in the coming year which, underpinned by satisfactory trading in 1999, will position us encouragingly for 2000 and beyond.
