| Revision: 02/0731/2003
Construction:
TEADIT style NA-1040 is a non-asbestos
jointing-sheet material produced from cellulose
fibres, bonded with Nitrile rubber (NBR). It
is being manufactured by means of a hot calender
process under rigorous quality control standards,
registered and certified under ISO 9001.
Application / service:
Style NA-1040 is an excellent general service
sheet, formulated to handle medium pressures
and temperatures. Suitable for water, petroleum
derivatives, diluted alkalis, brine, animal
and vegetable oils, general chemicals, aliphatic
and aromatic solvents, neutral solutions etc.
Style NA-1040 is also recommended as an economic
insert for PTFE-envelope-gaskets.
