      • 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.

      • 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

      • 基于PTFE层压制品和修改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

        • 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.

      • PTFE, FEP, PFA and PVDF High temperature heat shrink tubings

        ElringKlinger Engineered Plastics is manufacturer of Heat shrink tubing made from Polytetraflon™-PTFE or Moldflon™-FEP, -PFA and -PVDF.

        Our heat shrink tubing from PTFE, FEP, PFA and PVDF is manufactured from selected raw materials. The tubing, which is expanded by a special heat treatment, shrinks back almost to the original diameter when subjected to heat treatment once again.

      • Assemblies

      • Assemblies integrate a variety of technical requirements in a single component. They increase our customers’ vertical integration, thereby optimizing logistics processes by reducing the number of parts of suppliers and of parts to be purchased.

        A component from a single-source minimizes the complexity involved with parts assembly and streamlines the customer’s supply chain. ElringKlinger Engineered Plastics helps you combine, manufacture, and supply assemblies made of complex plastic components, metal parts, and sealing elements.
