Flexible connections at mobile and vibration-exposed equipments and aggregates in research and industry.
Highly flexible, self-supporting and dimensionally stable corrugated pipe made of transparent perfluoroalkoxy copolymer PFA/TFA with circular waves concentrically arranged around the longitudinal axis.

Transport of fluids of all kinds and qualities in laboratories and pilot plants as well as in small production facilities.
Connecting tubing for equipment used in clean room technology, radiochemistry and chemical technology under extreme thermal and environmental conditions.
Flexible fluorocarbon tubing of high thermal, chemical and mechanical stability, free of extractable components. Small flow resistance and only slight tendency to adhesion of solid matter due to smooth inner surface with antiadhesive properties. Electrically non-conductive, resistant to aging even under unfavourable environmental conditions such as moisture, acid as well as solvent vapours, radioactive radiation and weather effects.
Chemically resistant to amines, aldehydes, carboxylic acids, esters of carboxylic acids, dioxane, halogenes, halogenated solvents, conc. mineral acids, nitric oxides, oxygen, sulfur dioxide, sulfur trioxide, carbon disulfide, hydrogen sulfide, hydrogen peroxide, aqueous salt solutions of any concentration and many other acids, lyes and solvents.
Chemical, thermal and dielectric properties virtually identical to those of PTFE, but suitable for thermoplastic processing (welding, injection moulding, deep-drawing).
In comparison to PTFE: Higher light transmission, hardness, mechanical strength and dimensional stability (reduced cold flow tendency). Lower diffusion of media (reduced permeability) and higher compaction due to the injection moulding process. However, reduced mechanical machinability.
Highest thermal resistance of all meltable fluoroplastics
Very high heat distortion resistance
Very high pressure resistance
Very high chemical resistance
Low friction coefficient
Excellent UV and weather resistance
