- End Uses
Fluon® has been designed for paste extrusion at low to medium reduction ratio of high quality tubing with good transparency. Typical end uses include high quality hose for high pressure gasses and in the automotive industry as fuel lines. The low SG of the sintered tubing makes it suitable for production of convoluted tubes and hoses.

Regulatory & Compliance
- Food Contact Approval
Information on food contact approval is available from AGC Chemicals Europe, Ltd sales office.
- Disposal
Waste polymer should be disposed of by landfill in accordance with any local regulations for the disposal of products of low toxicity or may be incinerated under approved controlled conditions.
Technical Details & Test Data
- Processing
Fluon® CD086E can be processed by paste extrusion of a lubricated mix followed by drying and sintering. Further information on these techniques may be found in Technical Service Note F3/4/5, "The processing of Fluon® PTFE coagulated dispersion powders".
- Extrussion Pressure
Customers can tune Fluon® CD086E to their specific extrusion conditions by choosing from higher, or lower extrusion pressure versions.
Packaging & Availability
- Packaging Type
- Packaging
Fluon® CD086E is packed in plastic kegs with plastic lids containing 25 kg.
Storage & Handling
- Storage and Handling
Fluon® CD086E should be stored in clean dry conditions between 15ºC and 18ºC to ensure it does not become compacted and remains easy to sieve.
The lubricated mixes of powder should be stored at 25ºC for 24 hours before use in air tight containers to ensure that the lubricant is evenly distributed and that the powder will preform and extrude uniformly.
For further information on processing and properties of CD086E tubing may be found in technical information sheet "Fluon® CD086E for Hose and Tubing".
