TESNIT® Compressed Gasket Materials - High Performance Line

BAX 5000

Environment friendly gasket material with supreme mechanical properties.

BAX 5000 is an excellent fiber gasket material based on aramide fibres. A high content of aramide fibres in combination with binders assure outstanding mechanical properties. The material is free of harmful nitrosoamines (certified by MRPRA) and fibers which are hazardous to human health, and if it is applied at higher temperatures no significant emission of harmful degradation products has been detected. BAX 5000 is in compliance with the requirements of DIN 28091-2 and BS 7531 Grade Y.

Properties and application

BAX 5000 has excellent mechanical properties and shows good sealing properties in joints subjected to high mechanical loads such as screwed joints with narrow annular faces. High torque retention and good sealability ensure low maintenance costs and high joint safety. BAX 5000 is appropriate for the sealing of oils, fuels, gases, Freons, solvents, non-aggressive chemicals and many other media. Surface treatment provides simple replacement after use. Due to its excellent mechanical properties and physiological excellence it is particularly applicable to valves, hot-water boilers and radiators as well as for general use.

Basis
Composition	Aramide fibres

Surface treatment

The standard version has a non-stick top and bottom layer. Additional surface treatment is generally unnecessary. Special treatment with graphite, silicone or PTFE on one or both sides is available on request.

P-T diagram

	General suitability using common installation practices under the condition of chemical compatibility.
	Max. performance is ensured through appropriate measures for joint design and gasket installation. Consultation is recommended.
	Limited application area - Technical consultation is mandatory.

The Pressure - Temperature charts are the most current method of determining the suitability of a gasket material in a known application. Maximum figures for temperature and pressure can be misleading. Max. temperature and max. pressure represent maximum values and should not be used simultaneously. They are given only for guidance, since this max. values depend not only on the type of gasket material but also on the assembly conditions. Use the pressure and temperature graphs to check suitability of chosen gasket material for your application (combination of pressure and temperature).

σ _BO diagram

This diagram describes characteristic values of gasket materials for static seal for use in flanged applications. Given the wide range of gasket applications, these values should merely be considered as a means of assembling the sealing behaviour of gasket under sevice condition. Sigma diagram shows you maximal allowed surface stress (maximum in service compressive stress) on gasket by operating service temperature for different material thickness.
