PTFE
The base characteristics of PTFE are the ones offering a unique combination of:
- low coeffi cient 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 fi lled with glass fi bre, bronze, graphite, carbon.
The values from the associated chart are obtained by the analysis of both the moulding and extrusion process. The fi rst 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 specifi c requirements of the application, are gained using the expertise of Guarniflon’s R&D team.

FEP
Termoplastico fl uorurato con ottime caratteristiche termiche, elettriche ed eccellente inerzia chimica.
Ampiamente utilizzato nell’industria per la sua resistenza alla corrosione fi no a temperature di 200°C.
Utilizzato come fi lm da sfogliature trova applicazione come distaccante nello stampaggio di compositi, ottimo come materiale di saldatura fra resine fluorurate. |

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 fl uidity during the processing, the fi nal products in PFA – especially the skived fi lm - are absolutely porousfree, hence very suitable for electrical applications. |

MFA
It’s a semi-crystalline fully-fl uorinated melt processable fl uoropolymer which offer the highest temperature rating and broadest chemical resistance of all melt processable fl uoropolymers. 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 fi nished surfaces. This makes MFA a good candidate for the semiconductor, electronics and biologic applications. |
