Technical Details & Test Data

Processing: Fluon G307 can be molded following generally established procedures. For full details consult the Fluon Technical Service Note F1, "The Molding of PTFE Granular Powders" and F14, "Isostatic Compaction of PTFE Powders".

Molding

Compression ratios: 2.7

Preforming: 4500-5000 psi with slow, steady compression

Sintering

The article must be heated above the gel point of the resin (648ºF [342ºC]) to achieve compete sintering. Maximum sintering oven temperatures are usually 700ºF (371ºC) and higher, depending on the wall thickness of the article.
USP Plastic Class VI: Fluon Polytetrafluoroethylene (PTFE) has been submitted for testing according to USP class VI protocol. The material complies with the requirement under USP guidelines for implantation, intracutaneous, and toxicity study. Even though our material meets the requirements, it is always good practive to test material as used in its final platform.

Testing of the finished part is the responsibility of the manufacture or seller if certification is required.

If additional information is required, please contact the Fluon PTFE Technical Service Department for assistance.

Packaging & Availability

Packaging Type: Drums
Packaging: Fluon G307 is supplied in plastic kegs with 25 kg (55 lbs) per keg.

Storage & Handling

Storage and Handling Procedures: Prior to use, Fluon G307 should be stored in a cool, dry environment, preferably between 59 and 65ºF (15 and 18ºC). Excessively warm powder will have impaired flow characteristics. Atmospheric moisture may condense on excessively cold powder if a keg is opened in a warm room. Such condensation may cause cracked moldings. The temperature of PTFE powder should not pass through PTFE's transition point (66 - 68ºF [19-20ºC]) during the molding process. If this occurs, cracked moldings may result.
