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.
