 In Good ShapeMore Degrees of Freedom for Seals Made of Thermoplastically Processed PTFE The PTFE "MoldfIon," which is suitable for thermoplastic processing, allows seals to be injection-molded. New degrees of freedom with regard to shaping enable complex assembly component geometries to be achieved. In the past, such geometries could only be manufactured by means of complex cutting or machining processes. In addition, the material offers benefits like improved cold flow and lower wear.

Spring-energized PTFE seals for use in high-pressure piston pumps Particularly well suited for use in cleaning equipment pumps are seals made from modern PTFE materials. PTFE's key properties are nearly universal chemical resistance (e.g. to aggressive cleaning additives), service temperatures ranging from -250 °C up to +250 °C, no water absorption, unlimited weather resistance, no aging and high anti-adhesivity. By combining suitable PTFE base materials with different organic and anorganic fillers it is possible to adapt the PTFE compound specifically to the application's requirements.. ...more Der Konstrukteur, 6/2006 |

 Tailored Plastic ComponentsPTFE generation with improved properties profile In terms of its chemical composition Moldflon by ElringKlinger is largely identical with conventional PTFE. Unlike PTFE, though, this thermoplastic material can be processed by thermoplast methods — a significant advantage with regard to economy and processing of large-volume PTFE production. New degrees of freedom in forming the material by means of injection-molding enable the realization of complex component geometries... cav - May 2006 |

 A NEW GENERATIONHigh-end PTFE and manufacturing technology lead to diaphragms with long service life. The market for diaphragms such as those used in pumps, valves, etc. is dominated by rubber-PTFE composites. Yet today nearly all composite parts can be replaced by homogenous PTFE diaphragms. This avoids previous disadvantages like separation, fiber cracks or crazing (frost-like internal cracks). Development costs are reduced significantly. Chemie Technik - May 2006 |

 Interior Lining for ContainersAnti-corrosion layers based on modified PTFE Corrosion of process apparatus has several undesirable consequences. For one, the damage caused to the apparatus itself and for the other, the contamination of process media by drag-in of metal ions. With modified PTFE, it is possible to protect equipment from corrosion, and media from contamination. Its chemical resistance and operating range from 250 to 260°C as well as its very high purity make this material suitable for a wide range of applications. cav - July 2005 |

Compound Know-how Leads to Innovative Solutions PTFE offers a wide range of uses, particularly for innovative solutions. This application potential can be further expanded and enhanced by combining PTFE with other materials or compounds like metal, elastomers or high-performance plastics. Also, by adding fillers, PTFE can be individually adapted to meet specific application requirements. Consequently, the use of PTFE as an engineering design compound requires comprehensive compound know-how. Konstruktion Zeitschrift für Produktentwicklung 06/2001 |

PTFE-Elements Replace Single Seals Machine components on pumps or valves are normally sealed using dynamic or static seals like O-rings. A novel approach consists of replacing single seals by PTFE-elements. This strategy does not primarily focus on the sealing element itself, but on the overall engineering design concept.

Individual Solutions Made of PTFE Despite its comparatively higher costs, PTFE is the number one compound for numerous applications. Practical application, however, not only involves the compound itself. Rather, taking advantage of the specific properties of PTFE is of crucial importance. This turns into a truly interesting proposition when designs deviate from the original standard solution to integrate several functions into one assembly component.

The PTFE Elastomer diaphragms are suitable for applications where severe loads are common. The forces that result from deformations are absorbed by the elastomer, while the PTFE lining, which is permanently bonded to the elastomer, provides protection against aggressive fluids. The PTFE diaphragms are used in metering equipment, in the pharmaceuticals and foodstuffs industries, in pumps for the chemical industry and in paint shops. The stroke of the diaphragm is determined by the shape and design of the beads, as well as by its effective diameter. cpp 3/2000 |
