MultiTex® S 8 – ePTFE Gasket with diffusion barrier

MultiTex® S 8 – ePTFE Gasket with diffusion barrier

KWO® MultiTex® S 8 is produced from 100% pure expanded PTFE without any pigments, inks or adhesives, and therefore especially suitable for clean applications.

A diffusion barrier ensures very high sealability at very low gasket stress.

The flexible material adapts well to sealing surfaces, compensates irregularities and seals at very low stresses.

Suitable for use in metallic flanged, as well as stress sensitive connections.

Seals most chemicals across the whole pH range (0-14).


Advantages

  • Adapts well to sealing surfaces, compensates irregularities
  • Superior resistance to creep and cold flow
  • Very high sealability especially at very low stresses

Properties

  • High chemical resistance
  • UV resistant, non-ageing, unlimited storable
  • nontoxic, biologically inert

Applications

  • Flange connections
  • Heat exchangers
  • Reactors, glass lined flanges
  • Uneven or distorted flanges
  • Pharmaceutical- und food processing equipment

Properties

  • BAM – suitable for use with fluid and gaseous oxygen
  • TA-Luft regulation and blow out safety acc. to VDI 2200
  • Specific values according to DIN EN 13555
  • FDA 21 CFR 177.1550
  • EC1935/2004 suitable for applications with food contact
  • USP Plastic Class for pharmaceutical applications
