Special gaskets & additional products
Faster, better, different – since 1997 we are putting our best efforts into fulfilling our customer’s wishes according to this motto. This includes the development of special solutions.
By coating the surface of a gasket or a profile the original properties of its material can be modified and enhanced. For example the heat resistance as well as the friction coefficient can be improved considerably by a polytetrafluorethylene (PTFE) coating. In addition most materials can be equipped with adhesives.
Standard PTFE coating for elastomers
Our standard PTFE coating is a fluoropolymer system with excellent gliding properties that is especially suited for flexible materials. Even without mechanical pretreatment it adheres very well to rubber materials. Instead of a closed layer it forms a shingle-like structure that is able to withstand elongation without being damaged. Thanks to this shingle structure it is particularly suited for elastic components which are undergoing deformation during application, e.g. sealing gaskets that are mounted on mobile elements in doors or windows.
The coating was specially developed for rubber but can also be applied to other materials. If complex shapes are being coated, the coating thickness can vary.
Coating thickness: 10 – 25 μm
Friction coefficient: 0.07
Surface finish: < 2 μm
Temperature resistance: - 40 up to + 150°C
Flammability: not flammable
Bending strength: excellent (48.000 folding cycles)
Standard self-adhesive coating for elastomers
Our adhesive coating is a solvent free, environmentally acceptable double-sided adhesive tape on a special paper medium. It is physiological harmless and exhibits excellent weather and ageing resistance. Thanks to its distinct viscoelastic properties it is very well fitted for coarse celled material.
Temperature resistance: -40°C up to +120°C
Glue type: acrylate
Medium: special paper
Cover: silicone paper, brown
Prototype construction ...
Prototypes are an important aspect of every product development process. Usually they mark the starting point for testing function, chemical and mechanical abilities as well as for revision, adaptation and improvement.
Thanks to many years of experience in the sealing sector as well as with very different production methods we are able to provide prototypes and initial batches made of cellular rubber, soft rubber or other materials.
This way our customers can put their products to test without buying expensive tools or losing time by waiting for type samples.
... instead of extrusion or molding die tools
Especially when developing a new sealing profile or a molded part the manufacturing of separate die tools in every new stage of the process is very elaborate. It causes high costs, a lot of effort and long delays. To sum it up: constantly designing new extrusion or molding dies is often not a realistic option.
This problem can be avoided by a separate prototype production. Even if it is often complex and requires a lot of experience with materials and manufacturing techniques it is usually faster, more flexible and a lot less costly than the manufacturing of samples using the final production processes like extrusion or molding.
Cut-outs, strips and sheets
In addition to customized gaskets and profiles we supply most materials in the form of sheets, strips, cut-outs and rolls.
In addition to our standard materials like cellular rubber, sponge rubber, soft rubber or polyethylene we of course provide special materials like Cellasto®, Sylomer® or Viton® as well.
