amboflon® FEP 2 and 7:
For the extrusion of semifinished products, profiles, tubes, wire coating, filaments, films, etc.
amboflon® FEP 10, 22 and 26:
For extrusion of wire coating and filaments as well as for injection molding.
amboflon® FEP plus and pro grades:
These special grades are characterized by an increased "flex life" (ASTM B470). They are typically used for cables that need to maintain their flexibility even at extremely low or high temperatures.
Product Description
amboflon® FEP (Fluorethylenpropylen (PFEP, Poly(tetrafluorethylen-Co-hexafluorpropylen), Poly(fluorethylenpropylen), Perfluor(ethylen-propylen)) – CAS-Nr.: 25067-11-2
amboflon® FEP, the copolymer of PTFE and 50-90% hexafluoropropylene is a high-performance, semi crystalline thermoplastic. Available as granules, powder and reinforced compound. Typical applications are the production of transparent tubes, the food- and pharmaceutical industry as well as medical technology, apparatus engineering, electrical engineering, wire coating and the use in photovoltaic modules.
Technical Specifications
Long-term use temperature: (-)200 - (+)205°C
Short-term use temperature: (-)250 - (+)250°C
Thermal decomposition: from +375°C
Melting temperature: 255 - 285°C
Density: 2,12 - 2,18 g/cm³
Dielectric constant: ≤ 2,15 (106Hz)
Tensile modulus: 400 - 700 MPa
Characteristics
amboflon® FEP shows comparable chemical and weathering resistance as well as burning- and electrical properties to PTFE. The impact strength is higher and the strength, stiffness and temperature resistance are lower than PTFE. However, the stiffness and wear resistance can be significantly increased by filling with graphite or ground glass fiber. The permeability of amboflon® FEP is improved compared to PTFE and PFA. amboflon® FEP is physiologically harmless and therefore suitable for food contact according to FDA 21 CFR 177.1550 and (EC) no. 1935/2004 - (EU) 10/2011. Above the decomposition temperature of 420°C, toxic and corrosive fire gases form. Please refer to the Material Safety Data Sheet when processing.
Resistance
amboflon® FEP shows comparable chemical and weathering resistance to PTFE. It is radiation resistant and sterilisable. amboflon® FEP is resistant to lubricants, oils, fats, gasolines, aliphatic and aromatic hydrocarbons, LM, alcohols, esters, ketones, alkalis, ammonia, amines, acids, ozone, hydrogen peroxide, hot water, water vapor and other substances. It is not resistant to free alkali metals. The contact leads to decomposition.
Flammability
amboflon® FEP is self-extinguishing and is there-fore classified as V-0, according to UL-94 (DIN EN 60695-11-10).
Processing
Process: injection moulding, extrusion, pressing, sintering, transfer moulding, rotomoulding, rotolining, powder coating, etc.
Processing temperatures: extrusion, injection moulding: melt temperatures of 315 - 370°C (tool 200 - 230°C).
amboflon® FEP can be processed for example by injection moulding, extrusion, extrusion blow moulding, pressing, sintering, transfer- and rotomoulding. The cylinders and screw(s) must be made of highly corrosion resistant non-ferrous alloys (nickel-molybdenum). The crystallinity ranges from 40 to 67 % at 210°C, depending on the tempering process. FEP tends to melt fracture. For colouring, we recommend our amboflon® colour-masterbatch.
