補充信息

Processing

• Algoflon S 121 is processed according to methods used for normal and isostatic molding. In particular isostatic molding technology uses

hydrostatic pressure on a diaphragm positioned over or around the object to be preformed. Prior to use, the powder must be conditioned

above 19°C / 66°F.

• The molding process 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.

• Algoflon S 121 is specially reccommended for isostatic molding since it shows good flowability to fill completely complex or narrow molds.

Furthermore it provides smooth surface finishing.

Storage and Handling

• Algoflon PTFE free flowing powders must be stored and handled carefully to achieve defect free molding. Preforming is most effective when

the powder temperature is uniformly 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 Free Flowing 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 S 121 is packaged in 45 kg nonreturnable drums. Each drum contains one bag liner made of polyethylene resin.
