FDA Compliance

Fluon Polytetrafluoroethylene (PTFE), when sintered to high temperatures common in the industry, is compliant with the compositional and extraction requirements for United States Federal Food and Drug Administration Regulation (FDA) 21 CFR 177.1550.

Technical Details & Test Data

Processing

Fluon® PTFE G355 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 (648°F [342°C]) to achieve compete sintering. Maximum sintering oven temperatures are usually 700°F (371°C) 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, intra-cutaneous, and toxicity study. Even though our material meets the requirements, it is always good practice 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.

Storage & Handling

Storage and Handling Procedures

Fluon G355 should be stored in a cool, dry environments, preferably between 59 and 65°F (15 and 18°C). 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 – 68°F [19 – 20°C]) during the molding process. If this occurs, cracked moldings may result.

Handling Precautions

Within its working temperature range, PTFE is a completely inert material, but when heated above 750°F (400°C), it gives rise to gaseous decomposition products or fumes that can produce unpleasant effects if inhaled. Fumes can be produced during the sintering process. The inhalation of these fumes is easily prevented by applying local exhaust ventilation as near to the source as possible.
Smoking should be prohibited in workshops where PTFE is handled because tobacco contaminated with PTFE will, during burning, give rise to polymer fumes. It is therefore important to avoid contamination to clothing, especially the pockets, with PTFE and to maintain a reasonable standard of personal cleanliness by washing hands and removing any PTFE particles lodged under the fingernails.
