PTFE

The base characteristics of PTFE are the ones offering a unique combination of:
  • low coefficient of friction
  • excellent chemical inertness
  • non-adhesive surface
  • wide temperature range withstanding (–200° C to +260° C), excellent dielectric properties.

PTFE Standard Compound

 The more common compounded PTFE grades are filled with glass fibre, bronze, graphite, carbon.
The values from the associated chart are obtained by the analysis of both the moulding and extrusion process. The first column on the left sums-up the basic data of virgin PTFE G400, in order to compare with the values of the different compounds.

PTFE Special Compound

 Special “G” compounds compliment the series of standard “G” compounds.
Although these products are not widespread in the market, they provide solutions that standard compounds will not permit. Special compounds, designed to meet the specific requirements of the application, are gained using the expertise of IPM’s R&D team.

FEP

 Fluorinated thermoplastic material with excellent thermal, electrical and chemical inertness properties.
Widely used for different industrial applications for its excellent chemical resistance up to 200° C.
The most common format being, skived film, it can be used as non-stick material in the compression moulding processes, or melting material between fluorinated resins.

PFA

 Fluorinated thermoplastic material, offers the advantages of being thermo-processed whilst at the same time having the properties of PTFE, with excellent chemical and mechanical resistance for applications up to 260°C. Thanks to its fluidity during the processing, the final products in PFA – especially the skived film - are absolutely porousfree, hence very suitable for electrical applications.

MFA

 It’s a semi-crystalline fully-fluorinated melt processable fluoropolymer which offer the highest temperature rating and broadest chemical resistance of all melt processable fluoropolymers. It is an ideal choice for extreme thermal and chemical environments. MFA exhibits the outstanding thermal behaviour and chemical resistance found in PTFE, PFA and FEP. In addition, parts made with MFA have been shown to have smooth finished surfaces. This makes MFA a good candidate for the semiconductor, electronics and biologic applications.
