Seals for lamps

By using polymethylmethacrylate (PMMA) in combination with sulphur-cured compounds stress cracking can occur.

By means of our own compound making and production we dispose of a wide-range of compounds meeting these requirements in various Shore hardness.

Use our strong points as your advantage.

Our experienced team of product developers in combination with our possibilities regarding simulation together with our extensive possibilities concerning reinforcing supports, adhesives and sealing compounds or surface treatment systems is the basis to find also for your application an ideal solution. 

As reinforced materials we are using

  • punch strips
  • stamped metal strips
  • wire reinforced strips

delivered in a flat performance by certified suppliers.  

Before we are able to use the reinforced materials for the extrusion we have to shape it to an U-form by means of special bending tools regarding the required dimension and shape. 

To keep the tooling costs as low as possible we check already during the calculation process id we can use an already existing bending unit or a similar bending unit. 

High grade EPDM-profiles enable a flexible application even in cases of high temperature variations  (-35° to + 120° C.). 

Surface refinements with our high-grade and permanent slip-coating systems achieve a minimisation of friction and are also available regarding peroxide-cured compounds.

If required our profiles can be coated online also with flock.

Furthermore an assembly regarding frames or lengths including cut-outs or drilled holes is possible.
