End Uses

Fluon CD123E and CD127E are high extrusion pressure polymers which have been designed for paste extrusion at low to medium reduction ratio into tubes including pipe liners. Their excellent stability makes them ideally suited to the long sintering cycles needed when making thick section tubes for pipe liners.

CD123E has higher extrusion pressure and may be used at reduction ratios from 15 to 300:1. CD127E may be used at higher reduction ratios than CD123E. CD123E is also suited to the manufacture of electrical tapes of good tensile strength and good thermal stability.

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 CD123E and CD127E 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".

This information sheet contains typical property data which should not be used for specification purposes.

Packaging & Availability

Packaging Type

Drums

Packaging

Fluon CD123E and CD127E are packed in plastic kegs with plastic lids containing 25 kg.

Storage & Handling

Storage and Handling

Fluon CD123E should be stored in clean dry conditions at 15ºC - 18ºC to ensure they do not become compacted and remain 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.
