KWO MultiTex Sheet – ePTFE Gasket Sheet

KWO MultiTex Sheet – ePTFE Gasket Sheet

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

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
  • Reactor columns, glass lined flanges
  • Uneven or distorted flanges
  • Pharmaceutical- and food processing equipment

Certificates

  • BAM – Suitable for use with 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
