POLYTETRAFLON® fluoropolymer tubing features almost universal chemical resistance, excellent anti-adhesion and electrical properties, very high temperature resistance and physiological harmlessness. Fluoropolymer tubes are divided into two classic production processes.

  1. Paste extrusion: This covers all PTFE tubing
  2. Screw extrusion: Covers PFA, FEP, ECTFE, ETFE and PVDF

PTFE SpiralschlauchIn paste extrusion PTFE paste is formed by adding a lubricant in a cartridge and this is then pressed into a blank mould and then into a die. This involves an external sintering process over a relatively long section. The lubricant here volatises at 100%.

There is currently a variety of PTFE pastes on the market, which all have different characteristics. For this reason Polytetra offers so-called industrial quality and pressure hose quality. Various paste materials can be used for the industrial quality.

The testing process is limited to production and batch testing. POLYTETRAFLON® pressure hose quality tubing is exclusively made from replicable paste materials, which are also subjected to single coil testing. Here the customer is guaranteed to get the same material when reordering as was supplied in the first order.

Screw extrusion has the advantage that it can be produced continuously in almost unlimited lengths. Screw extrudates also feature greater material homogeneity.
