PTFE Rotary Shaft Seals (PTFE lip seals) are often used in applications where traditional elastomer solutions would be unable to deliver the required level of performance.
Equipment which is required to operate with high pressures, high speeds or that requires a dry running rotary seal, can often only be accommodated by using products where the seal lips are manufactured from the latest filled PTFE polymer technology.
Several standard ranges of PTFE lip seals are available to cover a broad range of applications. In the case of very demanding or extreme applications, a custom designed solution may present the best opportunity to deliver the required level of performance.
PTFE piston seals (PTFE rod seals) as Spring-energized seals and memory packings are always the ideal choice for sealing static or dynamic pistons and rods.
ElringKlinger Engineered Plastics is manufacturer of PTFE seals and offers a broad range of standard PTFE piston seals and PTFE rod seals, supplemented by customer-specific special solutions.
In this area, the focus is on modified PTFE materials and compounds with specifically adapted properties.
PTFE Piston Rings and Guide Rings (Rider rings) for dry-running applications are currently a focal point of technical development.
They significantly reduce a machine’s operating costs and, in today’s increasingly environmentally aware society, make it easier for operators to fulfill stricter environmental legislation.
ElringKlinger Engineered Plastics offers a whole range of PTFE piston sealing rings (Guide rings or rider rings for reciprocating compressors).
These products are made possible thanks to our comprehensive technological know-how and our many years of experience with countless customer projects.
We are able to create specially developed PTFE compounds, e.g., for dry-running seals and guides, such as those used in reciprocating compressors—with the help of innovative production processes. Thanks to their specifically adapted filler proportions, these compounds offer decisive advantages:
For plain or friction bearings an important prerequisite is that they work reliably over a long period of time and do not fail even under low-lube or dry running conditions.
Plain Bearings made of MoldflonTM or highly wear-resistant PTFE compounds are the solution from ElringKlinger Engineered Plastics.
They are particularly suitable for applications involving high p•v values and high thermal loads. This makes plain bearings (friction bearings) of ElringKlinger Engineered Plastics the ideal choice for use with aggressive media.
What’s more, our plain or friction bearings can be used with confidence in applications involving contact with food or pharmaceutical products.
PTFE bellows are used, for example, as compensating elements between engineered parts. By specifically using different fold geometries, any combination of properties can be achieved as required—for example, high flexibility or compressive strength.
The outstanding material properties of PTFE allow bellows to be used increasingly in the medical and food sectors, as well as in general industry.
A diaphragm is normally used to reliably separate different media or spaces with different pressures. One of the main requirements is chemical resistance to aggressive media. Precisely defined flexibility and a long service life are also important criteria.
ElringKlinger Engineered Plastics has a wealth of experience in this field. We are able to fulfill precisely defined sets of requirements by tailoring the material and design of the diaphragms exactly to the relevant application. PTFE or filled PTFE offer just the right combination of mechanical, thermal, and physiological properties for this range of applications.
PTFE tubes offer the ideal properties for transporting liquid foodstuffs as well as pharmaceutical products and aggressive chemical liquids. ElringKlinger Engineered Plastics has established itself as a specialist for tubes based on PTFE, a product increasingly used in medical engineering, the chemical industry, and mechanical and electrical engineering.
Besides solutions using pure PTFE, compounds featuring carbon, glass, bronze, or graphite are also used in order to achieve exactly the right material properties required for a particular application.
Heat Exchangers made from Moldflon™ PFA - ECTFE - PVDF - PP or PE have been manufactured by ElringKlinger Engineered Plastics for many decades. Standard solutions as well as custom designs are available and supplied across a wide spectrum of global industries.
The Heat Exchangers are designed using computer models based on customer-specific process data. Apart from the process-related design, the Heat Exchanger is also classified according to the categories and modules of the Pressure Equipment Directive 2014/68/EU.
This includes the strength analysis, design and manufacturing documentation as well as the final pressure test.
Each Heat Exchanger comes with an inspection certificate and a declaration of conformity.
High-performance plastics based on PTFE are an extremely versatile material that can be given precisely defined properties and allows engineered parts with complex shapes to be produced. ElringKlinger Engineered Plastics has the necessary expertise to offer a comprehensive range of services in this area and can create the optimal solution for every requirement.
These include, for example, combinations of PTFE and metals, elastomers, and other plastics. Various additives can also be used with PTFE in order to achieve precisely tailored material properties.Besides PTFE and PTFE compounds, ElringKlinger Engineered Plastics also uses other high-performance plastics and a wide variety of processing technologies. This leads to the creation of innovative design elements that open up new application areas and make a vital contribution to reducing costs and improving competitiveness.
Laminates are reinforced PTFE, consisting of a PTFE film or plate on the one hand and a substrate on the other. The layers of material are firmly bonded to each other.
Possible substrates include fabrics, fibers, or knitted fabrics as well as films. They consist, for example, of glass, metal, ceramics, elastomers, or high-performance polymers.
The structure may comprise two or more layers, and constructions with up to 7 layers are not uncommon.
Furthermore we assemle PTFE coated glass cloth to cut length or stamped parts, specially to PTFE coated glass cloth conveoyer belts.
When modified PTFE is used as a film material, these properties are enhanced further by:
A complex solution or a component with specific geometries is not always required. Sometimes all that is needed is a material with very specific properties to fulfill a certain task.
Besides individual solutions and a broad range of standard products, ElringKlinger Engineered Plastics also offers semifinished products in the form of foils, films, plates, rings, rods, and hoses. The available material versions are virgin PTFE, modified PTFE, porous PTFE, or a PTFE compound with specific fillers. These can be tailored to your requirements in order to precisely fit your application.
All semifinished products made by ElringKlinger Kunststofftechnik are available in the typical standard sizes:
Alternatively, customer-specific sizes and geometries within the given maximum dimensions can be produced. This is done using a machining process, for example.
