Insulation Tubing

FEP tubing and UV spirals in the context of application

Fluorinated ethylene-propylene (FEP), also known as a tetrafluoroethylene-hexafluoropropylene copolymer or perfluoro(ethylene-propylene), is a polymer made from the monomers tetrafluoroethylene and hexafluoropropylene. The material is fundamentally characterized by chemical inertness, high-temperature resistance, high flexibility, and good melt processing. GREMCO takes advantage of these exceptional material properties to manufacture special FEP tubing for a wide range of applications. These products are made from 100% certified PFOA hyperlink-free resin and thus meet the highest quality standards. Furthermore, FEP tubes are easy to clean without the risk of damage from any solvents.

Usage as UV spirals

Due to their UV resistance combined with a high transmission rate, FEP tubing is ideally suited for use as UV spirals in water purification systems. While water is pumped through the FEP spiral is permanently exposed to direct UV radiation. This kills potential germs in the water, while the FEP tube remains unaffected. To provide the most efficient and direct radiation, GREMCO manufactures the spiral using a unique manufacturing process. The tubing is wound around a UV lamp through which the liquid passes during the cleaning process. This complex manufacturing process allows the finished product to transport a significantly increased volume of water into the effective area of the radiation for an extended period of time. The process is equally suitable for the purification of polluted industrial water as well as for the treatment of contaminated groundwater. In conjunction with modern filter technology, drinking water quality can be achieved.

Other applications for FEP tubing and UV spirals

Primarily due to their chemical inertness in combination with the excellent formability of the material, FEP tubing, and products, as well as UV spirals, are used for numerous other applications. These include:

• groundwater analysis
• medical technology
• food industry
• printing industry

Furthermore, in addition to our standard products, we also manufacture customized versions adapted to specific requirements in a cost-efficient manner.

Groundwater analysis

In groundwater analysis, FEP tubes are used to transport water. Due to the exceptional purity of the material, the groundwater can be pumped through the hose to the surface without risking contamination thus resulting in false measurements.

Medical technology

In medical technology, FEP tubing is primarily used as catheters or in the field of endoscopy. In addition to the aforementioned chemical inertness, which precludes the contamination of the transported fluid during infusions, for example, the aspect of biocompatibility is decisive for the outstanding suitability of FEP in medical applications. Also, FEP can be sterilized by all conventional methods.

Food industry

Thanks to the uncomplicated cleaning of FEP tubes, they enable a wide variety of applications in the food industry. According to information from the US Food & Drug Administration (FDA), contact with any type of food has been proven to be harmless.

Printing industry

FEP can also be produced as heat shrink tubing and is used for coating transport rollers in printing machinery. The high surface quality prevents adhesion, contamination, and discoloration of the material to be printed.
