Made to measure - for commercial use

You are looking for a producerfor seals made ofEPDM (ethylene propylene rubber) - a material that is characterised by a longer service life compared to other materials. The area of application of these seals requires the following material properties:

  • High resistance to ozone, UV radiation, heat and weathering
  • Very good electrical insulating properties
  • High elasticity and excellent dynamic properties
  • High resistance to water, salt solutions, alcohol or weak acids

These characteristics make EPDM a ideal material im Automotive sector, in the Baubranche or in the consumer goods industry. In these industries, EPDM seals often have to be optimised and customised to the application environment. You should therefore contact KREMER!

        EPDM and the new challenge of LED technology

        When using EPDM gaskets, new challenges must be taken into account when dealing with LED lights. LED lights contain circuit boards in which silver-containing solder is processed. Due to the sulphur contained in the EPDM cellular rubber, the silver triggers chemical reactions in EPDM. In the worst-case scenario, this sulphur migration can cause the LED light source to fail.

        An EPDM cellular rubber manufacturer and supplier to our company has identified this problem and found a solution. He uses peroxides instead of sulphur for production. This causes a change in the network structure of the material, which in turn results in small differences in tensile strength and elongation at break. However, these differences can be neglected, as in sealing applications it is the density, compression set, water absorption and available Shore hardness, all of which are within similar tolerance windows, that are decisive.

        Due to the higher density of the periodically cross-linked EPDM cellular rubber, seals made from this material are characterised by better resilience. Accordingly, this material is favoured for use in the lighting industry.

        Self-adhesive film as an assembly aid for seals

        The use of self-adhesive film for elastomer products can be helpful for the user for several reasons. Self-adhesive seals are used, for example, for overhead installation of a seal or to prevent loss during transport of pre-assembled components.

        If gaskets, especially profile gaskets with self-adhesive film, are used as an assembly aid for installation, this means that the self-adhesive film has no influence on the function of the gasket after installation.

        Punched gaskets self-adhesive on film are a convenient solution that makes installation easier and safer. If the adhesive film is to have a function other than that of a self-adhesive film for mounting purposes, this must be explicitly stated in the enquiry. Our product advisors will carefully check the information about the intended use and include it in the quotation according to the possibilities.

        In addition to the proper processing and handling of the self-adhesive film in the production of the gasket manufacturer, the storage of the elastomer finished products at the customer's premises plays a decisive role in the durability of the self-adhesive elastomer and silicone products.

        The right processing

        • Ensure sufficient and even contact pressure.
        • Processing tools (including hands) must be free of release agent.
        • In the case of extreme loads on bonded joints, it should be noted that the maximum adhesive strength is only reached after approx. 24 hours.
        • Avoid permanent tension on the bond.

        Underground:

        • Do not apply to surfaces containing silicones, paraffins or waxes.
        • Do not use paints with adhesion-reducing additives.
        • Ensure freedom from dust.
        • Ensure freedom from plasticisers.
        • Ensure dry surfaces.
        • Cover as smooth, closed surfaces as possible.
        • Exclude chemical reactions of the surfaces.

        Temperatur:

        • The optimum bonding temperature is between 20 and 30°C in dry rooms.
        • If possible, do not work below 10°C.
        • Storage temperature at 18°C and approx. 55% relative humidity.

        Influences that impair the adhesive strength of the self-adhesive film:

        • High humidity, grease, oil, dust and/or dirt on the surfaces of the parts to be bonded.
        • Plasticiser migration.
        • Improper storage (deviating from DIN 7716).

        Storage and shelf life

        As a general rule, the following applies to self-adhesive Seals only a limited shelf life can be assumed. The shelf life of the film may be shorter than the warranty period of 12 months for self-adhesive products. It is therefore particularly important that the storage and processing instructions are observed. We recommend that self-adhesive products are processed within six months.

          Warranty conditions "Self-adhesive products"

          The product must be processed within six months of delivery, taking into account the above-mentioned storage temperature, humidity and processing instructions. No liability/warranty can be accepted for products processed at a later date.
