Rubber Foils

Proven quality “made in Austria”

Our rubber strip is a tried-and-tested product that is highly regarded by our customers and used in a wide range of composite designs. Our rubber strip undergoes a special chemical pre-treatment giving it a specific surface texture that guarantees optimum adhesive properties. This is where sandwich structures using conventional systems may fail. Our product portfolio offers the right rubber strip for almost every application with our wide range of material thicknesses and widths.

Rubber strip for sandwich systems

Material thicknesses from 0.13mm up to 2.1mm and any width from 6mm up to 1220mm are available upon customer request. In addition, we offer different hardness or damping degrees of the film:

Key features

  • Black: A1468, nominal value 60 Shore A
  • White: A1469, nominal value 60 Shore A

Each item is available in standard black or in a white variant if the customer requires the construction to have a specific look or design. The strip is supplied in ready-packed on rolls, ideal for series production and easy processing.

Anti-torsion perforated strip

The Semperit anti-torsion strip is a specially perforated version of the proven Semperit rubber strip. The perforated strip is a custom-made product that we offer in addition to the rubber strip for sandwich systems. In the case of very large-surface bondings, problems often arise with air pockets, or it is feared that a "release layer" could allow too much torsion.

Performance Range

The product offers a large number of constructional, commercial and technical advantages for various applications, including:

  • Making it possible to create a bond between incompatible materials
  • Adhesion even under high dynamic loads
  • Equalising temperature-related expansion and differing stress-strain coefficients
  • Suitabile for use over a wide temperature range
  • Vibration damping up to the point of component decoupling
  • Flexible tolerance equalisation, backing material and filler material
  • Application under the surface of the component, preventing extrusion on impact

One of the factors that contribute most to the product's success is its low price compared with alternative sandwich materials and adhesion systems.

Application examples in skis and snowboards, on steel edges, binding plates, and in the tip & tail.

Application Examples

Semperit’s many years of experience in the high-tech world of the ski industry are incorporated into this sandwich system. Our special rubber compound has proven extremely successful in the complex sandwich systems that predominate this sector and has come to be an integral component of many constructions.

Our strips are produced in Austria and is used as ski strips in the skis and snowboards made by virtually all the popular brands, OEMs and in customized top-end brands worldwide. Manufacturers looking for lightweight construction in the aviation and bodywork construction sectors also benefit from the advantages that Semperit strip provides.

Surface Texture and Adhesive Properties

The principal advantage of Semperit strip is its outstanding adhesive properties that are the result of using a wide variety of bonding processes, adhesive types and materials. We developed these unique adhesive properties by using a specific surface texture and treating it in a specially developed chemical process designed to achieve maximum surface roughness and tension for optimum adhesive impregnation. The end result is a very strong yet flexible bond with the adjacent materials.

Our strip is often recommended as a solution to bonding problems. It can be used as an intermediate layer between components that cannot be bonded or are difficult to bond within a composite construction.

The use of our strips results in a better degree of adhesion than directly bonding between the individual materials. A secure and durable bond is ensured even under the highest dynamic loads.
