PTFE Tubing | Fluorotherm

PTFE tubing is therefore dry molded or extruded in hydraulic extruders with (paste extrusion) or without (ram extrusion) lubricants. Paste extrusion of PTFE yields flexible tubing. However, it occurs in a batch process and thus long continuous lengths are limited to the batch size, unlike the melt-processible fluoropolymers FEP, PFA and ETFE.

Manufacturing of PTFE Products

PTFE products having complex shapes are manufactured by Isostatic moulding / sintering process. The Isostatic compaction of PTFE consists of filling a flexible mould made out of Rubber / Polyurethane with Free Flow Granular PTFE Resin, closing & sealing the flexible mould, inserting this mould in a fluid contained by a Pressure Vessel, sealing the vessel & pressuring the fluid @ 350 kg/cm².

News | A Comparison of PTFE and PFA Fluoropolymers in

PTFE is found extensively in wetted parts in pumps and valves, and in other appliions where the nuer of parts required are too small to justify the tooling costs required in manufacturing PFA wetted parts. And while both PTFE and PFA are high purity materials, have exceptional resistance to corrosive chemicals and harsh environments, and

PTFE, FEP, & PFA Fluoropolymer Tubing

PTFE (Polytetrafluoroethylene) a fluorocarbon-based polymer, is a resin supplied in powdered form, which is mixed, preformed, and extruded into a paste, and then finally tubing. PTFE tubing can be used in a wide variety of appliions due to its high chemical resistance, high and low temperature capability, resistance to weathering, electrical

Permeation - Kongsberg PTFE Hose | PTFE Hose Manufacturer

The voids in the PTFE hose can be controlled and reduced by either putting the hose through a slow sinter or even a post sinter process. These processes help to make the PTFE molecules more crystalline and thus reducing the size of the voids and reducing the amount of permeation. Very small molecular gases can also pass through the amorphous
