Processing Information

 

If transport or storage temperatures are too high the material can agglomerate in its container. In such cases, it is advisable to store the material for 48 hours at below 23ºC (73ºF) and then sieve it (mesh size 4 mm) (.16 in) before filling the mold. To achieve optimum properties, compression molding should be carried out within a temperature range of 23ºC to 26ºC (73ºF to 78ºF) at a pressure of

20-25 MPa (2900-5100 psi). The sintering temperature should be in the range of 375ºC to 380ºC (707ºF to 716ºF).

 

Product Form and Packaging

 

Dyneon TF 1645 PTFE is supplied in moisture and dust-tight plastic drums with a polyethylene liner.

Quantity per drum: 50 kg (110 lbs.)

 

Order quantity per pallet: 300 kg (660 lbs.)

 

Storage and Material Handling

 

Dyneon TF 1645 PTFE has an unlimited shelf life provided it is stored in a clean, dry place. Dyneon TF 1645 PTFE is hydrophobic, and generally do not require drying before processing unless high humidity conditions create surface moisture adsorption.

 

Management System - ISO 9001 and ISO 14001

 

All Dyneon design, development, production and service facilities have achieved a global ISO 9001 registration for their quality management system. In addition, our Gendorf, Germany location has achieved ISO 14001 for its environmental management system.

 

Regulatory

 

Dyneon TF 1645 PTFE is in compliance with FDA regulation 21 CFR 177.1550. It is the responsibility of the user to determine whether its specific formulation and intended use comply with applicable laws and are suitable for its intended applications.

 

Safety/Toxicology

 

These are fluoroplastic materials, so normal precautions observed with fluoroplastics should be followed. Before processing these products, consult the Material Safety Data Sheet and follow all label directions and handling precautions. General handling/processing precautions include: (1) Process only in well-ventilated areas;

(2) Do not smoke in areas contaminated with powder/residue from these products; 

 

(3) Avoid eye contact; (4) After handling these products wash any contacted skin with soap and water. Potential hazards, including evolution of toxic vapors, can exist if processing occurs under excessively high temperature conditions. Vapor extractor units should be installed above processing equipment. When cleaning processing equipment, do not burn off any of this product with an open flame or in a furnace.
