Description

Modified PTFE gasket material manufactured with bi- axial orientated chains to obtain a tight seal for demanding applications. This material has a rather high compressibility characteristics and low minimum seating stress value. Therefore this material is highly recommended for low torque applications, plastic pipe systems and flanges, as well as glass and ceramic lined equipment. Blue in color and produced with Modified PTFE and hollow glass micro spheres as a filler.

Product Data Sheet

Application

Specially designed for use in low bolt loaded constructions for sealing applications across whole pH-range: Therefore extremely suitable for glass, ceramics, and plastic lined or distorted flanges and even flanges with light surface irregularities.

Advtantages

For all flange connections, also for flanges with easily damaged sealing surfaces (including glass lining); good electrical insulating properties; non-ageing.

Chemical Compatiblity

Particularly for use with strong acids (except hydrofluoric acid) and alkalis. Other applications include solvents, fuels, water and oil. A chemical resistance list is available upon request.

Delivery Options

Flange gaskets and sheets are available in thickness of 0,5mm, 0,8mm, 1mm, 1,5mm, 2mm, 3mm and 5mm. Other thicknesses available on request. Standard gaskets can be supplied in accordance with ASME B16.21, EN12560-1 as well as EN1514-1. Non-standard or special gaskets can be manufactured according to customer drawings, or by given sizes or E-drawing.

Temperature

Particularly suitable for temperature from – 240 °C up to 260 °C.
