补充信息

Processing

• Algoflon® F 7 is processed according to methods generally used for normal compression molding. Prior to use, the powder must be conditioned above 19°C/66°F.

• The processing involves typically two steps: preforming and sintering. Initially the powder is compacted into a preform. This is then sintered using precise sintering (heating and cooling) cycle to take the temperature above the PTFE crystalline melting point to attain the final article. The preforming pressure, dwell time at maximum sintering temperature and cooling rate are all established according to the shape and size of the final item.

 

Storage and Handling

• Algoflon® PTFE fine cut powders must be stored and handled carefully to achieve defect-free molding. Before use the temperature of the powder must be conditioned above 19°C/66°F (between 21-27°C/70-81°F). Below this temperature the powder is difficult to mold without cracks. Temperatures that are too high should also be avoided to prevent powder lumping and poor flow.

 

• Storage and handling facilities should be clean since even very small foreign particles can cause defects in finished products. Keep resin drums closed and clean. Good housekeeping and careful handling are essential.

 

Safety and Toxicology

• Before using Algoflon® PTFE fine cut powders, consult the product Material Safety Data Sheet and follow all label directions and handling precautions.

 

• As with all PTFE materials, handling and processing should only be carried out in well ventilated areas. Vapour extractor units should be installed above processing equipment. Fumes must not be inhaled and eye and skin contact ought to be avoided. In case of skin contact, wash with soap and water. In case of eye contact, flush with water immediately and seek medical help.

• Do not smoke in areas contaminated with powder, vapour or fumes.

 

• See Material Safety Data Sheet for detailed advice on waste disposal methods.

 

Packaging

• Algoflon® F 7 is packaged in 25 kg nonreturnable drums. Each drum contains two bag liners made of polyethylene resin.
