End Uses

Fluon® CD090E is a low extrusion pressure polymer which has been designed for paste extrusion at high reduction ratio for wire
coating or small diameter tubing with good transparency. Typical end uses include various types of wire, for example, hook-up
wires and computer back panel wires, and small diameter tubing including spaghetti tubing where excellent transparency and
surface finish are required.

Regulatory & Compliance

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.

Food Contact Approval

Information on food contact approval is available from AGC Chemicals Europe, Ltd sales office.

Technical Details & Test Data

Processing

Fluon®CD090E can be processed by paste extrusion of a lubricated mix followed by drying and sintering. Further information these techniques may be found in Technical Service Note F3/4/5, "The processing of Fluon® PTFE coagulated dispersion powders".

Safety & Health

Safety in Use

Users must refer to the relevant Material Safety Data Sheet.

Packaging & Availability

Packaging Type

Drums

Packaging

Fluon® CD090E is packed in plastic kegs with plastic lids containing 25 kg.

Storage & Handling

Storage and Handling

Fluon® CD090E should be stored in clean dry conditions between 15ºC and 18ºC to ensure it does not become compacted and
is 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.
