GREENSEAL PRO 180 is a non-asbestos jointing sheet based on cellulose and synthetic fibres with inorganic fillers, bonded in an NBR binder matrix.
Suitable for thermo-hydraulic applications at low bolt loads. Approved for use with potable water, foodstuffs, oils, alcohols and glycols. Antistick surface finish on one side minimizes flange adhesion and simplifies gasket replacement.
Typical Applications
Water supply & distribution systems
General-purpose industrial piping
Food & beverage processing
Thermo-hydraulic flanges at low bolt loads
