The compressive strength at a certain predetermined compression value is one of the most signiﬁcant mechanical characteristics of PTFE, in a wide range of service temperatures. Flexibility strength, plastic memory and hardness, are additional characteristics of PTFE products.
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.
Special compounds compliment the series of standard “G” compounds. Guarniflon® special compounds are gaining more and more market share due to the increasing demand for solution to high tech industrial applications.
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.
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 porous- free, hence very suitable for electrical applications.
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 ﬁ nished surfaces. This makes MFA a good candidate for the semiconductor, electronics and biologic applications.
THV Fluorothermoplastic (a polymer of tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride) provides a combination of performance advantages such as ability to band to elastomers and hydrocarbon based plastics, flexibility and optical clarity.
A polymer of tetrafluoroethylene and ethylene, known also by its acronym ETFE, is a thermoplastic fuorocarbon-based polymer (a fluoropolymer). It was originally designed to have high corrosion resistance and strength over a wide temperature range. compared to glass, ETFE film is 1% the weight, transmits more light and is also resilient, self-cleaning (due to its nonstick surface) and recyclable.
Polyvinylidene Fluoride, or PVDF is a highly non-reactive thermoplastic fluoropolymer a polymer of vinylidene floride. It is also known as KYNAR® (Arkema) or HYLAR® (Solvay Solexis). PVDF is a specialty plastic material in the fluoropolymer family;
