Sticks and seals permanently

Whether it’s butyl tape, butyl round cord with or without a core, butyl tape with aluminium lamination, special lamination, as a butyl section or butyl punched part or butyl in a barrel as barrel melting butyl.

EGO butyl tapes are malleable sealing tapes with precise profile structures, which have been used as an addition or alternative to the usual injection sealants for more than 40 years. The versatile material properties of the EGO butyl products and the individual forms offer an extraordinary range of possible applications. They comply with the application recommendations of the IVD leaflet no. 5. International test certificates and expert reports confirm the excellent characteristics of the EGO products.

Butyl characteristics

  • ready-to-use, non-reactive tapes, the properties of which do not change over decades
  • permanently adhesive and malleable with partly elastic properties
  • self-sealing and immediately functional after processing
  • stable in volume and solvent-free, resistant to ageing, weather and UV
  • outstanding resistance to water vapour
  • physiologically safe and environmentally friendly
  • virtually unlimited shelf life
  • excellent compatibility with most conventional construction materials, including bitumen and plasticiser-free foils and plastic components, such as polycarbonate, polyacrylate, hard PVC, polyethylene, etc.

Compatibility of the EGO butyl tapes with sealants must be confirmed by the respective manufacturers. We generally recommend using our EGO oxim and alcoxy silicone sealants.

Butyl qualities

The EGO butyl qualities generally differ in:

  • Density
  • Pressure resistance
  • Tensile strength
  • Impact strength
  • Shore 00 hardness and penetration
  • Tack
  • Inner tensile strength

Specific material properties

  • Surfactant resistance
  • Chemical resistance
  • Melting properties
  • Suitability for use with food
  • Microbiological resistance, and much more

Production engineering

Our flexible production engineering, developed in-house, ensures customised production with high quality standards (DIN ISO 9001). As a result, our EGO butyl tapes have an extraordinarily large product range when it comes to shape, structure and properties:

  • Block profiles in thicknesses of 0.5 mm to 40 mm and widths of 3 mm to 400 mm
  • Round profiles with diameters of 2 mm to 80 mm
  • Injections in round profiles as cotton, nylon, rubber or foam cores (for tear or distance protection)
  • All types of lamination, e.g. with foils, textiles, fleece or mesh
  • Rolls with outer diameters of up to 500 mm
  • Production of multi-strand large rolls
  • Delivery in disposable or reusable packaging
  • Delivery as bulk goods in barrels

Individual special profiles

We are happy to directly implement your individual customer requirements and offer EGO butyl tapes not only as tapes, but also in a wide selection of:

  • Special profiles (e.g. trapezoid or U shape)
  • Square and round profiles
  • Sections with lengths from 4 cm
  • Punched parts from a thickness of 2 mm
