      • PTFE Rotary Shaft Seals

      • PTFE Rotary Shaft Seals - PTFE Lip Seals - Best Choice

        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.

      • Engineered Parts

      • Individual Components with Specific Properties

        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.

        Materials

        • PTFE (polytetrafluoroethylene)
        • PTFE compounds
        • PE-UHMW (ultrahigh-molecular-weight polyethylene)
        • POM (polyoxymethylene)
        • PA (polyamide)
        • PEEK (polyetheretherketone) 
      • PTFE Laminates

      • Laminates Based on PTFE and Modified PTFE

        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.

        Properties

        • Outstanding resistance to a wide range of chemicals
        • Very broad functional temperature range, only limited at the upper end by resistance of the adhesive used
        • Very good antiadhesive properties
        • Dimensional stability and resistance to stress cracking
        • No embrittlement, no ageing

        When modified PTFE is used as a film material, these properties are enhanced further by:

        • Polymer structure with higher density and fewer pores
        • Lower permeability
        • Better weldability

        Application Areas

        • Linings in plant engineering
        • Components for electrical and electronic applications
        • Diaphragms in pump or sensor construction
        • Optically transparent compounds for textile construction
      • Semifinished Products

      • PTFE Foil, PTFE Sheets, PTFE Rods, PTFE Pipes

        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.

        Shapes and Dimensions On Demand

        All semifinished products made by ElringKlinger Kunststofftechnik are available in the typical standard sizes:

        • PTFE Foil and Films with thicknesses of 0.03 to 5.0 mm
        • PTFE rods or cylindrical hoses with a diameter of up to 500 mm and a length of up to 300 mm
        • PTFE Sheets or PTFE Plates in standard sizes up to 3,000 x 1,000 mm and thicknesses of 6 to 150 mm
        • PTFE Rings with a diameter of up to 3,000 mm

        Alternatively, customer-specific sizes and geometries within the given maximum dimensions can be produced. This is done using a machining process, for example.
