With technological advancements comes the discovery of new materials that will make the manufacturing process easier and better on both the producer and consumer of such products. Usually discovered after an extensive body of research into viable alternatives, this is the form through which fluoroplastics came to be in the market today.

As of the time of this writing, these materials have been processed by hundreds of companies in China only. This not only tells of its importance but the need to understand what they are – and how they can be effectively processed for the best results too.

What are Fluoroplastics?

They are polymeric substances which are formed by the replacement of some or all of the hydrogen atoms they carry by those of fluorine. Depending on the process of manufacture – which also determines how the chemical reaction will go – there can be diverse kinds of fluoroplastics at the end of the production.
Of these, we have

  • -          Polytetrafluoroethylene (PTFE)
  • -          Perfluoro (FEP)
  • -          Polyperfluoroalkoxy (PFA)
  • -          Ethylene-trifluoroethylene copolymer, and more.

They are also used in different ways for the fabrication of different units. Thus, the need at hand will determine which of these fluoroplastics will be made.

Manufacturing PTFE Rods

Of all the fluoroplastics, PTFE happens to be one of the most important in the bunch. This is not only because of the desirable properties of the materials but for the fact that it takes special care and expertise to work this substance.

l  The desirable properties of PTFE rod are as follows:
l  The applicable temperature range is extensive. It can keep soft for long-term use in the temperature from - 200 to 260 .
l  High chemical resistance. It is basically resistant to all chemicals except for some fluorides and alkaline metal solutions.
l  Excellent flame retardancy. It is defined as flame retardant material in the air.
l  Excellent insulation characteristics (regardless of frequency and temperature).
l  Low water absorption. Having the smallest surface tension in a solid material, it does not adhere to any substance.

It's because of these excellent performances that it can be used in many fields, such as chemical industry, machinery, electronic and electrical equipment, medical materials, etc., mainly for long products and mechanical parts.

When manufacturing PTFE rods for various purposes, such as:

  • -          Chemical valves in fluid handling industries
  • -          Gasket material for high heat/ chemical applications
  • -          Household items, e.g., frying pans, etc.

It is vital that extra care is taken to get the right product and desired features too.

Choosing the Right Equipment

When going for a PTFE rod forming machine, care has to be taken to ensure it meets specific standards.

The process has to be conditioned in such a way that the material is formed in the mold, but doesn't overlap with one another. This means that it has to be continually flowing while still allowing for enough retention to take the shape of the mold.

At the same time, this piece of equipment must be able to keep the PTFE at the desired temperature during different stages of manufacturing lest the substance wastes or forms wrongly.

These are all features that come with the PTFE hydraulic press machine from Dekuma which offers all of:

  • - High repetitive progress
  • - Active floating feature
  • - Continuous pressure maintained in the same body

In addition, the operation of a hydraulic press machine for the PTFE rod of Dekuma is simple, and the pressure, stroke, and closing height can be adjusted according to the requirements of the pressing process.

That way, the raw materials are well taken care of, mixed optimally for the suitable chemical reactions to occur, and the desired product is formed.
