Home PTFE Products PTFE Tape & Sheets
Offering 30 years of technical knowledge & experience
  PTFE tapes, sheets and films are used in a wide variety of industries including heavy electricals, electronics (for circuit boards), pumps and valves.

Stocked in thicknesses from 0.025mm to 6mm and in sheets of 75, 150, 250 and 300 square cm. It is available as virgin PTFE, mechanical grade PTFE, and can be filled with glass fiber or other materials to enhance certain properties, like hardness. All tape can be etched for bonding; etched material is stocked in standard sizes.

meet a range of industrial needs
  • Non-stick sealing surfaces on polyethylene bag sealers and packaging equipment, including L-Bar Sealers and Impulse Sealers
  • Guide rails and chute linings
  • Non-stick roll covering
  • Vinyl window manufacturing
 
  PTFE membranes are chemically stable and inert. They are suitable for applications involving aggressive organic solvents, strong acids, and alkalis. PTFE membranes are particularly suitable for preparing samples for HPLC analysis. The hydrophobic nature of the membrane also has applications for air and gas sterilization. The membrane is laminated onto a nonwoven polypropylene support web for improved strength and handling and can be used at temperatures up to 120C.

Chemically stable and inert
PTFE is the membrane of choice for use with aggressive solvents, liquids, and gases that can attack other membranes. It is resistant to most acids, alkalis, and solvents.

Applications
One of the major applications for the PTFE membrane is the clarification of corrosives, solvents, and aggressive fluids. This includes the important requirement in HPLC analysis for sample filtration where any solid particles can cause permanent damage to the column. The 0.5 m pore size is normally used. Air and gas sterilization make use of the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 m and 0.5 m. Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 m membranes.

WTP and TE membrane ranges
WTP membranes use a polypropylene grid as the support material whereas the TE range use a randomly arranged polypropylene support material.
