Game enough for new stuff?
Thanks to its chemical structure, it features one of the best available chemical resistance of solid materials, and the best resistance amongst plastic. It is also recommended for its high insulation properties and its low friction behavior, amongst other outstanding properties.
A large range of PTFE compounds and composites is also available to improve performance in specific uses, mainly to improve its mechanical performance.
PTFE is also supplied as tubes with large or thin tube wallsrods, films sintered or unsinteredtapes, liners or molded basic shapes sheets, rods, dimpled sheets. AS such, it offers good mechanical properties at high temperatures.
The main advantage of PFA is its high purity combined with a larger transformation panel: PFA can be injected or directly extruded, and thus offer a large range of complex parts with a competitive process.
PFA is also available in compounds offering increased stiffness or strength. This allows the use of its high chemical resistance, one of the highest available, in demanding mechanical applications. Virgin PFA is certainly the preferred material when facing high purity challenges.
It is therefore often used in chemical production or in semi-conductor industry.
Competitive processes like injection or direct extrusion offset its higher gross price. FEP is often preferred in applications with high transparency and with high volume requirements. PCTFE is a fluoropolymer, whose chemical structure includes chlorine. It also has a low absorption level, even for gases.
It is therefore a solution often considered in fluid handling systems or in the aerospace industry. PCTFE is available as basic shapes sheets, rods and tubes and as machined parts with high precision for such demanding applications. ETFE is the fluoropolymer specially designed for enhanced strength.
Where other fluoropolymers encounter mechanical stresses too close of their mechanical limit, ETFE is often a competitive solution. Impact and cracking resistance, abrasion, stiffness, all these mechanical stresses are no match for the material.
Glass fiber compounds of ETFE are also highly valued when applications need even better flexural modulus. ETFE is a thermoplastic with a full range of transformation processes available. It is most commonly supplied through molding, injection or film extrusion.
ETFE is often used in applications requiring transparency. PEEK is a thermoplastic polymer recommended for its high temperature resistance and its high dimensional stability. With its light weight, it can even replace some metal parts in harsh environments, where it offers improved efficiency.
PEEK compounds are common in demanding industries to achieve the best performance available. Also PEEK is a good composite matrix, available for proprietary continuous fiber composites. PEEK can be injected, extruded or molded.Overview of the fluorochemicals industrial sectors.
